*HP Elitebook 800 Series Owners Lounge*

Okay, since my local TigerDirect had the Samsung U28D590D in-stock within $25 of Amazon (and most resellers are charging more), I took a trip over and plugged in my Elitebook 840 G1. I updated the drivers to the latest Intel, which was a full version over the HP OEM ones.

Unfortunately, it seems it's limited to 2560x1440. I can only assume this is the limit of the i5-4300U / 4400 GPU. I tried using resolution override, and it was a driver/system bandwidth limitation. It let me define 4K at 30Hz, but it still wouldn't drive it directly out the DisplayPort.

I still decided to get the Samsung U28D590D as I didn't want to drop over $400 on a 2560x1440 panel when a full 3840x2560 panel was under $600. I also didn't mind the "imperfect interpolation" in upscaling the 2560x1440 output up to 3840x2560 -- 2:3 -- on the monitor. That was the nice thing about seeing it at TigerDirect too, I could make that evaluation.

Especially with my personal Clevo P650SE on the way in the near future, which should be able to drive it natively at 4K out of its ports.

Hi guys, got a conundrum here. I have the 840 G1 - on the whole happy with it but had a whole bunch of Windows / software related issues that HP will not entertain fixing. They are basically saying they'll replace hardware or give me a refund.

I picked up a ProBook 640 from eBay very cheap (not my ideal machine but decent enough for the time being). On unboxing I found the 640 had no backlit keyboard. It was a custom model. Other 640 machines come with backlit, and my 840 is backlit, the keyboard looks identical so my questions are...

Can the backlit keyboard be sourced anywhere? I can't seem to find it?
Would the keyboard from the 840 work in the 640?

Could anyone with experience here let me know your thoughts please?

Cheers

 

UPDATE ...

Apparently while the 840 G1's older Intel i5-4300U/4400 will refuse to push out 3840x2160 on DisplayPort, unlike a newer i5/i7-*H/4600 series, it will let me use a DisplayPort->HDMI adapter and send 3840x2160 ... at 30Hz. Now running full 4K.

I have a 2nd Samsung U28D590D on-order now. Hopefully I'll be running dual-4K by the weekend.

P.S. Get the HP DP->HDMI Active Adapter for use with the UltraSlim Dock 2013. I was seeing a bit of cut-out and flicker with the Accel Active Adapter.

 

I am using a 840 G1 and I just purchased a Huawei ME906E WWAN. I can install but the system did not want to boot, stay at the BIOS "escape or continue" screen. Is the card compatible? I am using the latest BIOS, any suggestion?

 

Hello, I want to upgrade a HP elitebook 840 that is now with 4 GB of ram on a single slot

Some website are explaining that dual channel is not well supported by laptops CPUs

Do you think is possible to use in the second slot a module of 8 GB DDR3? Or dual channel must be used with a module of same size?

 

Some low-power, loc-cost SoC platforms, like AMD's Processor 13h and 15h (Bobcat/Zacate and Jaguar/Kabini and Puma/Beema) only support a single chanel. But virtually all other designs are dual-channel. There are a few triple-channel options for mobile i7 designs, but they are not very commodity.

The only complaint as of late is that, as vendors get more and more focused on thinness, they are solidering memory and other components on the board. This then limits expansion and, to a lesser extent, could possibly limit performance. It also reduces cost, as people replace entire systems than upgrade these days.

Ideally the memory should be the same sizing across both channels. Timing should also match, but it is often overlooked or not always considered. I.e., a lot of people focus on the clock, which is only a portion of the burst throughput, and has extremely little to do with latency.

In the case the sizing doesn't match, depending on how the memory is allocated, the TLB pages it, etc..., there can be cases where there is a reduction in performance as all pages are addressed over one channel, when the pages are only allocated on one DIMM. But even then, depending on the TLB, interleaving and other access, that is not always an issue, as many TLB lookups and memory reads can be in-flight.

E.g., keep in mind that it's not uncommon for it to take 9+ cycles to even begin an actual read request from memory ICs.

I.e., SRAM cells of cache on-die or at lesat on-package (depending on level) might be in a single or a few cycles, but DRAM cells are still much, much slower, like in 10s of nanoseconds.

Synchronous clocks are only for the burst. It's not the actual "clock/latency" of the DRAM cells.

 

Any one can help me? Anyone install WWAN module in their 800?

 

New driver didn't help my WiFi issue. HP sent me a new WLAN module. So far no issues.

 

Late last week I finally uninstalled the HP Connection manager and replaced the HP WLAN driver with the Intel Proset drivers and software. Since doing such, I've yet to have a single issue with suspend and waking from other power states. The 5GHz connection has also become far, far more reliable too.

EDIT: Sure enough, the second I say something, it happens a few hours later ... WiFi failed to reconnect coming out of suspend, and I had to cold boot this morning.

 

Sigh. Well, I've only had one issue since replacing the WLAN module. I uninstalled the HP connection manager a while ago. The latest LAN driver causes issue. Try the one I linked. There's an issue with LAN/WAN switching with the latest one.

 

Upgrade HP Elitebook 840G1 display from 1600X900 to 1920X1080IPS??

Is this easy to do?
I just bought this notebook and the screen is crap. Too late to send it back.

Anyone done this before?

Thanks all

 

Hello.

Just bought a new G1 840 (FHD!). Very nice unit, though I'm still getting used to the keyboard.

One thing that did not occur to me when evaluating notebooks is the side of the power outlet. My laptop is oriented on the left arm of my couch, meaning that the power cord is sticking out and is a pain to deal with when moving the laptop from the arm to my lap on a daily basis.

I recognize that it's not feasible to re-arrange where the power inlet is on the 840. However, I do wonder if there are alternative power cords available that don't stick out so far (2 inches??) and would provide more of a flat experience at the power inlet.

Anyone?
Thx.
Jon

 

hi JonDeutsch,

There are after-market power adapters that have a "L" shaped power adapter-heads. Check out ebay or if there is Computer-mall near you, a store should have it. I bought mine at a Computer mall in Hong kong

 

Hi Bspiral,

the 1600 x 900 HD+ screen is crap? I heard its pretty good. What is wrong with the HD+ screen?

I'm still torn between HD+ or FHD. I'm hearing FHD screen reading txt and everyday usage is a strain on eyes...

 

Thank you! Any suggestions on what I should search for to find such a thing on ebay? I searched L adapter HP 840 and I found nothing... Thx!

 

Hi
It is not a IPS screen which should be better. The colours are washed out and have a narrow viewing angle. I have a 1600x 900 IPS on a bigger display and have no issues.


Regards

 

Security settings for Password and Fingerprint Reader??

My computer runs but asks me for my password after a few minutes. Where are the settings??

Thanks Gary

 

I think the HD+ screen has screen door issues. The FHD screen is pretty brilliant.

Not loving the keyboard, though. A bit too light.

 

Yes. What's the solve?

 

hi Jon,
here is an example. Notice the L-shaped adapter.

hi Jon,

Is the FHD screen ok for lots of reading text? Does it strain the eyes from your experience?

 

Thanks for the link. So, that eBay post does not indicate it supports the g1 840. How do you know (or how will I be sure) that it'll work with this laptop properly? Thanks!

The FHD screen is very hi res so yes the fonts are a bit small on average but remember Windows has a way to boost font size which should remedy any kind of squinting issues you may have.

HI Bspiral,

looks like an FHD 14" LCD screen is only about $90 USD.

The HD+ connector is: EDP-30P1L

Find out if the FHD connector is the same!

This FHD also has a 30 pin connector...if its the same as the HD+ connector, then you are good to go!

(Not sure if its direct plug and play. I"m guessing the connections cables are not the same)

There's a vide on Youtube showing how to replace the screen for 840: https://www.youtube.com/watch?v=3gqp3zK__Ak

There are a few links in the description. One of them leads to a service guide: http://h20628.www2.hp.com/km-ext/kmcsdirect/emr_na-c03943612-2.pdf

On page 66 of the service guide there are details on display panel replacement. Screen models, part numbers (can be used to search on ebay) are listed and detailed instructions on how to remove the screen. Inserting is probably done by repeating the steps backwards. There's only one connector, meaning all of the screen models are interchangeable as long as the size matches. It should be possible to upgrade 1366x768 up to 1920x1080 by just buying a corresponding screen. Unlike in the video it probably isn't even needed to remove the display assembly prior to replacing display.

 

In my opinion the FHD screen is easier to read. The text is smaller, yes, but the display has more contrast and less anti-glare coating so it ends up being clearer than the HD+ screen.

As far as the replacement goes, it more or less has to be fully disassembled. The plastic bezel surrounding the LCD can't clear bottom chassis unless the hinges are unscrewed. Then again, with deals like the $600 base model that is on sale at Newegg, it makes pretty good sense to get the FHD screen aftermarket and install it yourself.

 

Hi

Thanks for all who commented on replacing the screen on my 840G1. The FHD IPS matte screen is on back order.

I will see how it goes when I replace it.

Thanks Gary

 

Even after replacing the WiFi module I still have occasional trouble joining the network after bringing it out of sleep. Definitely have some buyer remorse at this point. I may do a fresh install of Windows and see if that helps....

 

hi win32asmguy,

very help information! thank you.

are you 100% the FHD screen is plug and play with the already 30 pin connector of the HD+ screen?

I assume the graphics card will just identify the new screen and scale appropriately?

 

It should be compatible. I disassembled my Elitebook 850 first before ordering the screen to verify the connector and screen dimensions. The one thing that I think doesn't work quite the same is that the backlight range might be a bit off. For example, with the old screen it seemed to get darker given the same level of backlight brightness in Windows. However, it still gets darn good battery life (~7 hours web browsing) so I don't consider it an issue.

If you can find an AUO B140HAN01.2 to install I think it would be perfect. I like that one a bit more than the LG panel, even if the AUO is AHVA, their own copy of LG's IPS technology. Electrically it should be very similar to the B156HAN01.2 that I used, so I think it would be very likely to work.

 

Hello. I am interested in knowing if I can retrofit a fullhd panel on a hp 820. Is it possible?

 

HP has no FHD options for 820, only 1366x768 LED and a 1366x768 touch-enabled. Maybe from other models of different manufacturers but it's a hard guess. In previous posts there are panels from Thinkpad TX40 line suggested. Maybe from X240 as it has an eDP 30 pin connector so maybe this panel: New LCD Screen LED Display LP125WF2 SP B1 SP B2 for Lenovo ThinkPad X240 | eBay ?
The panel seems to have the connector in the right placement as a 820 display.
And a relevant thread about changing panels for X240: forum.thinkpads.com • View topic - Upgrade Display on X240?

You might have to venture out and buy it for testing, maybe returning afterwards if it doesn't work out for you.

 

I don't think that it would work. FHD appears to be 2-lane eDP while HD is 1-lane eDP. It is most likely that the cable HP made for this model is only capable of 1-lane eDP as they do not sell it with a FHD screen. It should be possible to upgrade from the SVA HD screen to UWVA HD screen, however.

 

Do you happen to know what model of IPS screen I could upgrade to? The stock TN panel is just so bad.

 

Where you buy AUO panel and how much is it?

 

Proud new owner of an 840 G1: HD+, 240gb SSD, 8gb ram, no discrete graphics.

I will add 256gb m.2 SSD and upgrade to 16gb DDR3L ram.

Decided to go with the 840 instead of the zbook 14 because of SIGNIFICANT cost savings and type of usage i'll mostly be doing on it.

Its amazing the low prices they now have on ebay for 840's with HP warranties!

this baby should last me a good 4-5 years

 

I solved it by going to device driver, properties, power management, uncheck "Allow the computer to turn off this device for power saving".

 

I tried that when I was running Windows 7 but I just put 8 on it and it's only happened once so far. Definitely not the OS. Some type of hardware issue.

 

Without unchecking it, I have it once a while too which is annoying. I eliminate it completely.

 

Thanks. I will try it with W8 and see how it goes.

 

I have HP support involved again. My 840's wifi issues are obviously hardware related.

 

Juste ordered one because thé price was right.

Was going to replace the HDD with an ssd and install Linux.

Anyone know what size drive it uses?

7 or 9mm?

Also what's the chip set for the WiFi? Intel?

I'm referring to the 820 g1 model with i5 4200.

Any known issues with Linux?

Hardware looks pretty standard.

 

I previously used the Latitude D820. I liked the soft feel of the keyboard, and I also found the touchpad more comfortable than a lot of the others I have used. I wonder if you can tell if the keyboard and/or the touchpad of the Elitebook 850 G1 feel similar to those of the D820? (I noticed from the picture of the 850 G1 that the touchpad at least looks similar.)

 

9mm should work fine. You can also add a M.2 SSD and use it as a Linux / Windows boot drive if you want to keep the HDD too.

All hardware should be supported under recent kernels, except using multiple displays via the 2013 docking station, due to lack of support for the DP MST hub inside of the dock. Support is in kernel 3.17 but still needs some refinement in my opinion. If you are using a single display (connected to the dock) or VGA / DP connected directly to the laptop it works fine.

 

Will a 7mm drive need padding?

 

No. The HDD caddy screws into the drive from the side, then the caddy itself screws into the bottom of the laptop.

 

turns out 9mm won't fit. I had to some drive shuffling and transplanted a 7mm drive from an older unit.

M.2 drives are hella expensive. Does the laptop take mSATA?

Otherwise I might just pick up a crucial mx100 512 for 210$.

This is the one that you want. I think it is fairly priced given how tiny this thing is (you will find out when you see it!). I am sorry that the 9mm drive didn't work. I am able to fit an older Crucial M4 in my Elitebook 850 and it appeared that the caddy was the same thickness on both models...
