I haven't had those in my hands yet but IF it works like with the LVDS cables, there is 40 pins in boths cables and connectors. 30pin ones come with 10 wires physically missing.

I'm going to come back to the issue of the screens in a few weeks. I'm really bummed out right now. The WXGA is really quite usable, just grainy. But it is perfectly functional in the mean time.
One last thing, the synaptic touchpad settings, where are they??? There are really basic settings, and there are Windows 10 precision touchpad settings, but nothing more advanced. I was wondering if the sensitivity could be increased, because I would like the touchpad to respond using even less pressure. Is this possible? Or do I need a macbook xD -

That much options I have in my own 840 G2.
edit to add: I've replaced a few edp panels so far but I haven't taken time to actually examine them. It's just work -
Anyone have experience with this seller:

The only strange thing is that the brightness control on my 840 G3 is a bit flaky, the lowest brightness setting seems more like 50% brightness to me.
Also sometimes the brightness "jumps" when you change it.
EDIT: The panel is genuine. Looks identical to 840 G2 with FHD AUO panel. Coating is same as well, not grainy / not strong AG like some say the B140HAN01 has. At least I don't see it. Certainly not glossy though.
brightness works OK now, I hope it stays that wayLast edited: Feb 21, 2017 -
Strangely enough, HP does not list seperate part numbers for the QHD and FHD eDP cables. It is possible that the part number includes both cables, but that would be kind of wasteful. We need an HP expert/insider to get these kind of answers... -
found a 1.3 version in same reseller...checked is compatible

ok guys, I am back to this forum after few years. I use to live in Vaio world till they decided to stop making awesome machines.
to the topic:
I got this awesome HP 840 G3 laptop for work, but the screen is **** (720p , washed out colors etc ) i want to upgrade to the best resolution , best part no. possible. I see many references thrown across in this page and I am simply confused.
1) Can someone point me in the right direction to the vendor with best IPS hi-res. (1440p and 1080p) lcd i can purchase from. and will i need a 40pin cable for 1440p and if so where do i purchase it?
2) my laptop has fingerprint sensor committed (probably work CTO) is this an easy part I can purchase and self-install?
3) I like to add an additional SSD drive for personal OS install. Can I add a 2.5in or M2 SSD?
Appreciate your feedback ! -
1) best screen is B140HAN01.2 or 1.3 ( me too i want to replace original panel ...is very simple )
2) don't know
3) it support both, open bottom and see if now you have a m2 or a ssd ( default if i remember is m2 )corrado85 likes this. -
1) can you point me to a vendor which sells a legit panel . I hear some are selling "compatible" models and not the actuals.
3) according to a review, it has empty slot '1.2in SATA drive' See ref: http://www.notebookcheck.net/HP-EliteBook-840-G3-Notebook-Review.163267.0.html
does this mean I need to a get a 1.2in SSD drive which technically don't exist searching newegg.. -
I've looked at that review several times but never noticed the mistake. I have a built-in spellchecker in my brain...
It is actually 2.5" slot for any hard drives.
I just bought m.2 2260 ssd from ebay. Haven't received it yet but when I do, I'll be rocking 250GB m.2 and 500GB 2.5" SSD in my 840 G2.
For the screens, ebay seller bumblesale mentioned above seems like a decent one. I might try that myself some day, since my current screen has some clouding at the edge.DooMMasteR and corrado85 like this. -
looks like i'll be getting a 2.5" ssd and a screen as soon as I am ready -
I have Intel turbo boost on battery set to disable in BIOS, but turbo boost is still active. What gives?
-
Did anyone notice that HP managed to cram 5 extra watt hours into the battery of the 840 G4?
This begs the question whether the 51WH battery, type TA03XL, fits in the 840 G3. Any volunteers? -
I installed WIn 10 Pro on my 840 G3 (was shipped with Windows 7...)
Soundcard is not working most of the time (red cross over the speaker symbol), auto repair doesn´t find anything wrong.
Sometimes after reboot it works, most of the time not.
In device manager everything seems fine:
Conexant ISST Audio
26.04.2017
Version 9.0.81.0
Any idea? -
Well I have used the 840 G3 for a while and.... what can I say. It is an HP product I guess...
I still have this weird issue where I have the brightness set at 75% for example, and suddenly it jumps to 100%. It then stays there for a minute and reverts back to 75%. And I never touch the brightness control. It happens very rarely. I only use the Windows 10 brightness control on the bottom right, which goes in steps of 25%. If I use te keyboard shortcut, the entire brightness control screws up after a while. It is probably a unit specific issue
Battery life, that's another sad thing. 6 hours is possible, if I throttle the CPU to 1.6 GHz. Windows uses too much CPU from time to time, causing the CPU to burn 6,7 or more watts while doing nothing. Does anyone have a better fix for this, as the reduced performance is really annoying from time to time. I'm glad I did not buy a Core M device, however, because it really needs the boost frequencies to feel snappy in day to day tasks.
Touchpad is good but surface could have been better. Fingerprint is pretty damn good as well. Keyboard is nice enough too.
If I had to do it all again, I'd probably go for the Dell E5470. Especially now that the 5480 is an epic fail (terrible 1080p screen like the stock HP 1080p display)
-
Hey, sorry to get off-track, but did anyone find what was needed for swapping a QHD screen into a FHD 840 G3? I too am having trouble finding the 40-pin cable even with searching PartSurfer for a known QHD model.
-
So I still have problems with my 840 G3, and I believe it is hardware related.
The brightness still changes by itself randomly.
One time the WiFi adapter disappeared from the system and only returned after a reboot.
Sometimes is shuts off while in standby (hard power off). One time it shut off while loading windows.
Downgraded BIOS to 1.10 and brightness problem remains.
Sucks because I have a swapped screen, so I would have to put the original screen back if I want to use my warranty I guess?
Or they would take it back and then I might lose the screen, right? -
Hi. I can't find if the cpu is replacable in the 840 g1. I fear not and it would be disapointing compared to my other Elitebook 2560p and 8560p. Would like to upgrade from i5 to i7.

Google image search "elitebook 840 g1 motherboard" -> all motherboards in the pictures have soldered cpus.

Shame! Bad luck. I have bought the 2560p and 8560p second hand after i bought the 840 g1 new, and i really feel i have made a bad deal with the 840g1. Previous elitebooks are way better to me.
-
I also upgraded my 820 G3 a bit, now with an additional 500GB Samsung 850 EVO paired with the factory m.2 SSD.
Also got me a US-Keyboard, but some keys are not working on it, too badso I'll stay with my German keyboard, at least until I find another cheap one.
-
My 840 G2 always runs at full clock speed according to the Task manager, why?
I have checked settings in BIOS and Power options, but nothing helps so far. The CPU supports EIST. -
Has anyone bought the G2 / G3 or G4 4k (UHD) model?
I'm searching for the exact panel model. I think it's a BOE. Any help would be really really appreciated! -
I have acquired an 820 G2 with an AZERTY keyboard and would like to replace it with a QWERTY keyboard. I can find reasonably priced genuine 820 G1 keyboards but the genuine 820 G2 keyboards are very expensive. Are the G1 keyboards compatible with the G2 as I have seen people advertise the same item for both the G1 and G2 which implies they are ?
-
Any 840 G1 owners still around? What battery life are you getting on these things? I recently bought a 840 G1 off my work, because I really like the keyboard, the display and speakers. Overall very sturdy. It has the i7-4600u CPU. According to various tools, including the HP ones (BIOS) the battery is just fine and according to another tool I've used extensively in the past, there is no battery wear (incredble, but OK). Seemingly all good. But I get no where NEAR the battery life of various reviews I'm reading. According to Notebookcheck, I should get a 6 hours with light usage? I'm getting 4 at absolute best.

Hello Guys,
I bought a 820 G2 and so far I've been pleased with it (minus the sort of static sound I hear with all my headphones...)
Unfortunately, I've drop some coffee on the touch pad and despite my best efforts, there is some damage. After cleaning and some driver changes, the touchpad works, as well as the 2 top buttons, and the lower right one. Nothing seems to make the left click works though and it's extremely annoying.
I have changed the keyboard on a number of elitebook laptops over the years, but never the touch pad. Is it easy? Can't say that there are a lot of touchpads available on ebay.
Any ideas and/or suggestions? Thanks and have a great weekend. -
There is no Revolve 810 Owners Thread on this forum??

I was given a brand new HP EliteBook 820 G3 yesterday by my employer.
All in all, I like the little beast. However, I have found the following nuisances:
-the TN display with the HD resolution (1366x768) looks ridiculous; it is not very bright and has a weird blue cast
-the keyboard is flexing in the middle/right part
-pointer buttons are very soft/spongy
-sometimes the fan starts making noise over nothing
So apparently this laptop costs around 1600 euros in Europe, that feels too much to be honest. I would not recommend it for that price. -
Thanks -
I figured that since I got a new HP EliteBook 850 G3 this past January at work, I might as well post my experiences with it in the first 10 months of ownership. My company's current standard laptop is the EliteBook 850 (G1-G4), and the previous standard was the EliteBook 8560p/8570p.
SPECS:
Intel Core i7 CPU (Standard work models have a Core i5)
8GB RAM (We have models ranging from 4GB to 16GB in our environment, depending on the employee)
256GB SSD (Most models have a 500GB HD)
AMD Radeon R7 Graphics (most models have Intel integrated graphics)
15.6" 1920x1080 LCD (most models have the 1366x768 display, while a few of them have the 1920x1080 touchscreen)
OS: Windows 7 Enterprise
REVIEW:
This laptop is MUCH thinner and lighter than my old laptop, which was an EliteBook 8560p. A huge factor in this achievement was the elimination of the Optical Drive, which I rarely have the need for at my job. And on the few occasions where I have needed one, I just use a USB optical drive (or use my old laptop).
The build quality is a definite step up from the 850 G1/G2, but still not quite to the level of the old 8560p/8570p. The laptop base is generally solid--slightly flimsy compared to the Abrams-M1-tank-like base of the 8560p/8570p, but it's definitely more solid and has a higher-quality feel than the 850 G1/G2. The lid has a silver metal finish, which hides dirt and ages much better than the black rubberized finish that the 850 G1/G2. The 850 G3 also doesn't suffer from the issue where the rear bottom left screw (the one underneath the power button) works its way out, something that I've seen numerous times with the 850 G1/G2 models at my office.
The keyboard is good, with very little flex. The key travel and resistance, while good, is not quite as good as the 8560p/8570. It's still better than most laptop keyboards, however (*cough* current MacBooks *cough*). The backlight is bright and has 2 levels of brightness (plus off).
There are a couple of flaws with the keyboard backlight, however. The first is that when the backlight times out, the num lock and caps lock indicators also turn off. This has thrown me off a few times where I don't realize that num lock and/or caps lock are on. If you set the backlight brightness to OFF, then the lock indicators will stay on.
The second flaw is that when the keyboard backlight is on, the num lock light appears to be on when it really isn't. Combined with the first flaw, it makes it especially difficult to tell the state of num lock. For these reasons, I typically keep the keyboard backlight OFF unless I'm working in a dark room. At least there's a numpad, something that was sorely lacking on the 850 G1/G2.
The touchpad works very well, and while the pointstick works decently, it still can't compare to the TrackPoint found on a ThinkPad. The mouse buttons have good travel and feedback, but feel slightly cheaper than the the ones found on the 8560p/8570p. There are buttons for toggling the Wi-Fi and the Speakers; unfortunately, the web browser and calculator buttons found on the 8560p/8570p are gone. One nitpick with those buttons is that in my office, it's difficult to see the lights on the buttons--they aren't quite bright enough--and silver finish on the laptop only worsens the issue. It seems like the 850 G4 units have brighter buttons, though.
The display is one of the bigger flaws with the 850 G3. On the 1920x1080 LCD that's on my laptop, the colors are somewhat washed-out compared with the 1600x900 display on my 8560p (the black level is too high), and the viewing angles are pretty mediocre for a 2016 laptop, with colors inverting when you look at the LCD from the wrong vertical angle. The colors shifted a bit on my 8560p's display from the wrong vertical angle, but nowhere near as much as on the 850 G3. The 1366x768 display, in addition to being washed out, has poor color (they're too "cold"-looking) and lacks definition. The only decent display on the 850 G3 I've seen is the touchscreen version, which has good colors. I have not seen the 4K display, unfortunately. The hinges do allow for a greater opening angle than the ones found on the 850 G1/G2, but nowhere close to the almost-180-degree angle that the 8560p/8570p allows.
The speakers are decent--they are MUCH better than the ones on the 8560p. They are mounted above the keybaord, resulting in a much clearer sound than the bottom-front mounted speakers on the 860p. The sound card has a nifty feature that remembers separate volume levels for headphones vs the built-in speakers. For example, if you have built-in speakers at full volume, you can plug in headphones and the volume will drop to wherever the headphones were at last. When you unplug the headphones, the volume will go right back to the level that they were before the headphones were plugged in. Unfortunately, the headphone jack doesn't detect headphones 100% of the time, causing the sound to go to the external speakers, even when headphones are plugged in. Unplugging the headphones and plugging them back in fixes the issue. I will note that just like other HP business notebooks, I had to disable the audio enhancements to get music to sound acceptable--by default, the sound card applies auto volume leveling, which makes music unlistenable.
The ports are pretty limited compared to the 850 G1/G2. There are only 2 USB-A 3.0 ports instead of 4. There is a USB-C port, but it is nowhere near as ubiquitous yet as the USB-A port is. There is a VGA port and a full-size DisplayPort, the latter I find unusual; I'd expect a Mini-USB port instead. There's also a SmartCard reader, an Ethernet Jack (VERY handy still where I work, especially when (re)imaging a PC or having to use a console cable on our networking equipment), an SD-card reader, and a SIM-card slot--even IF the laptop doesn't have a WWAN card (mine doesn't). The power jack is different from the 850 G1/G2 laptops--it is much smaller than before. Although limited compared to the 850 G1/G2, the port selection is still much better than most other ultrabooks out there.
As with just about every HP business-class notebook made in the last 12 years, there are 4 LEDs on the left side of the front edge--wireless, power, charging, and HD activity. Unfortunately, the LEDs are very difficult to see unless they are look at head-on. They are dim and have poor viewing angles. Previous HP business notebooks had LEDs that were much easier to see.
Upgrading the 850 G3 is MUCH more time-consuming than the 850 G1/G2, but still much better than most ultrabooks. Instead of simply sliding off a cover, you have to remove 12 screws from the bottom--11 of which are hidden by rubber plugs that are specific to their location, while the 12th screw is under the dummy SD filler card for the SD slot. Once the screws are removed, the entire bottom pops off, exposing essentially everything. Once the bottom is removed, the RAM, HD, SSD, WLAN module, WWAN module, and battery are all very easy to remove and upgrade. The battery is held in by 2 screws, but is still considered to be user-replaceable. Unfortunately, there secondary battery connector on the 850 G1/G2 is gone.
The loss of that secondary battery connector isn't really a big deal, however, as the battery life is VERY impressive. I typically get 8 hours of usage with the Wi-Fi on, LCD at medium brightness, running Firefox with a half-dozen tabs open, and occasionally using RDP. This is absolutely stunning. The Core-i5 versions with integrated graphics should get even better battery life.
The 850 G3 uses the HP 2013 UltraSlim docking station, which is not without its faults. It can be tricky to line up the laptop with the docking station, especially if the eject lever isn't all the way out (which can happen more easily than it should). It is also easy to accidentally not slide the eject lever all the way in to dock the laptop. I've also seen several docks in my office fail, either with faulty VGA ports, DisplayPorts that temporarily drop the signal, broken latch hooks, or complete failures of the dock itself. Interestingly, the docking station still uses the older, larger HP charger connector. For the record, my laptop came with a brand-new dock, and I have had no issues with it yet.
My particular 850 G3 performs very well except when first starting up, where it takes 1-2 minutes to either load the logon screen or to load my profile after I've logged on (stuck on the "Welcome" screen). After I'm logged on, however, the PC runs very, very fast.
There are 3 glitches with it, though. The first is the headphone jack glitch that I mentioned earlier. The second occurs when I attempt to put the laptop on standby mode. It tends to wake itself back up the second after I put it to sleep. Putting it back to sleep will cause it to stay asleep. The problem used to be much worse--it had a tendency to turn itself back on after shutting it down--but updating the sound driver has greatly mitigated the issue. The sound driver is still responsible for waking the PC back up after I put it to sleep, however. The third glitch is the most serious one--there were a couple of occasions where I left the laptop running overnight, with the power options set to never sleep, only to have the laptop go black and completely freeze up on my when I returned the next morning. I'm not sure what causes this, as I've only done this a few times, so I'm not going to list it as a con yet, as it could be a software issue for all I know.
Overall, I am very pleased with it, though I still use my old 8560p quite often alongside it, since it still works so well (and I have a dock for it at my house).
PROS:
--Very lightweight
--Outstanding battery life
--Wide range of configuration options
--Great performance on the higher-end configurations
--Good speakers
--Good touchscreen display
--Decent build quality, better than the 850 G1/G2
--Good touchpad

CONS:
--Mediocre non-touchscreen display
--Limited number of USB-A ports
--Upgrades are very time-consuming
--Docking station reliability issues
--Difficult to tell the state of caps-lock and especially num-lock when the keyboard backlight is on
--Front LEDs are very difficult to see
--Keyboard, while good, isn't quite as good as the 8560p/8570p keyboard
--Laptop likes to wake up immediately after being put on standby mode (sound driver issue)

I haven't noticed the keyboard or pointer buttons problems you mention. The keyboard's great on both copies that I have.
As to the screen, I ordered models with FHD (1920x1080) IPS screens (non-touch) and those are OK. Color gamut is limited, but the viewing angles and contrast are fine.
I'm amazed by the battery life on these notebooks. I can easily go for 10 hours of light web browsing and such; I could probably stretch it to 12 without too much trouble if needed.
One thing that was a disappointment to me though was the limited capability of the USB-C port. Sure, I knew from the get-go that it doesn't support Thunderbolt, but it was still a rude surprise when I found out that you can't even output video through it! Yep, it doesn't support the DisplayPort alternate mode of USB Type-C. That port is basically just like a regular Type-A, only with a different socket. It does support USB Power Delivery, but only in the outgoing direction -- you can't charge the laptop through it. I was hoping when I was buying it that that single USB-C port would "future-proof" my laptop but, alas, no. So when taking it on travel, don't forget its proprietary power brick or whatever else you need because none of the regular USB-C HDMI dongles or USB-PD power supplies will work. -
I just got my EliteBook 820 G4 with 1920x1080 FHD IPS... the screen is horrible! Colors are washed out and whites are yellowish.
My 4-year-old 2570p with a TN screen is brighter and clearer. I don't get it. I was expecting a big upgrade from the 1368x768 TN screen. -
I would describe the 820 G4 FHD IPS screens as OK, but just OK. The color gamut is not very high (<70% sRGB) and I'm guessing that's why the screen is not very vivid, lacking the "pop", especially if comparing to a screen with a glossy finish. I remember from my before-purchase research that pretty much all laptops with 12.5" FHD screens currently on the market seem to be like that, irrespective of the manufacturer.
As to the color cast, curiously, the two 820 G4s that I have exhibit distinctly different casts even though the screens appear to be otherwise identical. Could there be so much copy-to-copy variation? Anyway, the cast should not be hard to eliminate in software. I used a hardware colorimeter to calibrate mine and they came out looking decent.
