Modding - dv6t/dv7t Quad Edition (2011)

Sure, you disconnected the CMOS battery while you took the laptop apart.
Haven't you read the post, or are you just deliberately ignorant? In fact, if you do manage to get through the process I'm sure camiloml would like to hear the magic trick you performed so that he can remove his warning.

 

Yeah, because everyone takes the CMOS battery out when they work on their PC.

 

Yeah, leave it in and risk a short-circuit when you place the PCB somewhere.
There's a reason why you should take out the battery, disconnect the power-plug and drain the batteries when you take the stuff apart, right?!

 

Do you know what a CMOS battery is? It's a coin cell battery that supplies a charge when the laptop isn't powered otherwise. If you remove it, the BIOS and system clock reset. You don't take it out every time you service the computer because that would make no sense.

 

Obviously, you don't! "the BIOS" is stored on a flash chip. Some portions of the configuration settings are stored in a nvram which is buffered by a cmos battery [as is the rtc]. Futhermore, not removing it is sloppy, especially if you have a lot of little metal screws, panels and especially tools like pincette and screwdrivers around. Or do you like to damage anything "just" by accident?

 

Worrying about removing the CMOS "battery" is silly. I've installed so many motherboards that came from the factory or an OEM with the "battery" already in place. Wear an ESD strap. Don't be a messy pig and leave "your screws loose."

 

Ah, so you finally admit that you did take out the CMOS battery then. So it's as I said! And why should you lol?! Even if you will not admit it and continue to spread your own version [with your friend] of the story: I know that you are the sorry boys with the screwed bios and not me .

Well, Ceeluk removed it and rightly so to bring his laptop around. However, In a related way. I think I should point out that this laptop series does not have a PS/2 keyboard [yes, you firgured out the USB part your self], it's simply connected to the EC which performs the keyboard matrix scan.

 

The dv6t/dv7t, indeed, do have PS/2 keyboards, just that they connect via a ribbon cable, which are electrically PS/2...

 

Lol? No problem, I can help you laugh about yourself : your post. Remember: As I said it's the same "feature". Once you drain the power the laptop won't come back unless you either flash the original bios or clear out the nvram [by removing the cmos battery]. The same goes for if you make changes in the bios setup and try to save them: Again with the mod you have you end up with a semi-brick...

Me: I'm happily enjoying my AR9382 [WB222 is nice too but the driver is still wonky] without bricking even when changing the VT or going on a long trip .

No, they stopped putting PS/2 keyboards into laptops long ago, the same goes for the trackpad it may use the same PS/2 ports like the PS/2 mouses once did, but it's clearly not a PS/2 device, right? What you see there is just a ps/2 emulation by the EC. Much like "native" IDE support for SATA-AHCI devices nowadays.

 

The keyboard is PS/2... It connects via an SCH5317 which is a LPC (Low Pin Count) I/O (Input/Output) IC (Integrated Circuit). It connects to the "south bridge," which is the ICH10, via the LPC I/F (Interface).

The closest SMC data I could find related to the SCH5317 is the SCH5617C
SMSC - SCH5617C - Desktop System Controller Hub with Advanced, 8051?C-Based Auto Fan Control

ICH10 datasheet
http://www.intel.com/content/dam/doc/datasheet/io-controller-hub-10-family-datasheet.pdf



The touchpad is also PS/2. There is no emulation it's all hardware... One major reason PS/2 is still in use is serious sys/net admins & ISSOs like to disable USB for security reasons. That leaves what for an interface? PS/2...

I've been "playing" computers for a good long while now, go blow magic blue smoke up someone else's posterior; just don't run out of blue smoke.

Lots of info on the SCH5317 in the following HP document...

@witty, you should really resize that picture.
-------------------------------------------------------

@zuvieltext, sounds like you have a defective cmos battery, if the bios keep resetting to default in short amount of time.

And your bios defaults happens to have VT enabled which is odd.

The little coin battery helps to retain bios settings and time for like a year or more unplugged.

 

Just to let you know:
All Core i series mobile chipsets are integrated south bridge.
There's no ICH10 chip on the mainboard anywhere only the HM65 which has the LPC.

Where are you taking the SCH5317 from?

Last time I checked the DV6 had a ITE variant.
And a few posts seem to confirm my suspicion as well


> DMI string system-manufacturer: "Hewlett-Packard"
> DMI string system-product-name: "HP Pavilion dv6 Notebook PC"
> DMI string chassis-type: "Notebook"
> Laptop detected via DMI.
> Found ITE EC, ID 0x8518,Rev 0x02 on port 0x4e.

Also, the decrypted bios image has a "ITE Tech. Inc" string in the EC partition, so why would HP do that if it does not have a ITE EC?

But, back to the story. Have you ever noticed that the SCH5617C is a "Desktop System Controller Hub", since when did we switch to desktops or is it just you? Even more, it also has 2.88M floppy interface and other non-sense. So I have to ask you: Where did HP put the 2.88M floppy in your dv6 laptop?

Actually, it's much better than that the Synaptic pad emulates PS/2 all along the way and they'll finally decided to drop it. And back to the keyboard: yes it is still "matrix scan" and no ps/2 is anywhere to be found there. If you are still skeptical take a look at the ribbon which connects the keyboard. Don't you think HP would go for a smaller cable if they could, after all PS/2 only needs 4 lines, right? BTW: You don't need to open your laptop for that, just look at page 64 of the dv6 maintenance and service guide, at point 7 they have a mockup of the matrix scan cable.

You see, I've been working with computers for a good long while now. So, what is this all supposed to mean? Maybe once you stop playing, you will rethink your position again. Until then, there's no point in getting upset.
Ceeluk is already sad enough .

No, thank you I'm fine . Everything works here.

 

Hey does anyone know if you can upgrade the dv6-6150 (i5-2410) to an i7? does the bios differ from one in the dv6 quad editions? I wanted to get the cheaper i5 version cause i would replace the cpu with and i7-2820 anyway..

 

Umm, in theory it is possible with certain CPUs. Worth it, however? I would say not. Here is what i have found. I don't know much about this, but the i5 page on intel says it supports sockets FCBGA1023 and PPGA988, while the i7 says sockets FCBGA1224 and FCPGA988. Clearly not identical. The max power draw also is larger, so you might burn out components on the MB. If you decide to try, I commend you for the effort, but I don't think it will be easy or perhaps even possible.

 

if the internal cooling system on the i5 and i7 machines were the same, i'd think that swapping cpu's wouldn't be much of a problem..It would of saved me about 50 euro to buy the i5 and then the i7-2820 instead of buying the i7-2630 version directly, and it would have got me a decent performance boost also..oh well, i might just stay on the 2630 (as if it were underpowered haha)..Could you recommend a dual channel lvds cable for an upgrade to a 1080p screen? I saw you're thread

 

"zuvieltext" regardless of what you think you know, a 8042/compatible microcontroller is used as the dv6t's keyboard controller. In modern computers, this microcontroller is hidden within the motherboard's chipset, which integrates many controllers in a single package. Nonetheless, this device is still there, and the keyboard controller is still commonly referred to as "the 8042," no matter how old the information is, it is still relevant.

I used quotes when I said I "play" with computers, way to pick up on sarcasm.

 

Think? This is not something about "believing" you can always tear open your laptop components and look for yourself. Actually, you should do that once. The "8042/compatible" microcontroller you are talking about is actually more like a "8051/compatible" microcontroller. Sure you'll say that the 8051 is an "enhanced" 8048, but then the original 8051 was never 8042/compatible since it had a different pin mapping and more importantly a different ISA so meaningful binaries/programs for the 8048 would not work on the 8051 and vice versa. If you want, you can continue with the path but then I would like to skip the "4004/compatible" talk and go straight to "transistor/compatible" or "tube/compatible" since neither is pin-compatible nor binary-compatible. " "

I "understand" that you are now a bit "embarrassed" about what you said previously [either due to your "limited" expertise or abundance of "conflicting" knowledge]. Fair enough, it seems like you have run out of blue smoke and settled down and sort of drifting away from the actual subject. But please if you no longer want to talk about how the keyboard matrix is connected to the EC, then just say it.

 

The fact stands that the dv6t uses both a PS/2 keyboard and touchpad. I place a challenge, delete the "i8042prt.sys" from your dv6t's system32 directory and then come back via a dv6t/dv7t and show us all how well that it works without that driver.

I have never seen a USB-HID that uses IRQ1 and and an I/O address port in the 60 – 6F range... So, if the dv6t & dv7t do not use the PS/2 interface then what do they use, huh? Quit side tracking and prove me wrong, I am waiting.

By the way, no embarrassment on my part. I like this; it is like poking a blind and deaf dog with a stick. I know it is mean but it is still quite funny.

 

I see now, where you take your "wisdom" from. Well, I'm still waiting for a previous request. Remember how you claimed that the dv6/dv7 houses a
SCH5317? Now, have you already took a closer look at the EC or not?

But I can do "two" for the price of one post. So back to your "request", because I have a serious problem with that. You see I'm not sure what part of "emulation" (last paragraph) you did not understand? So see, based on your logic, it should be possible to remove the i8042prt.sys from Windows 7 running in a Virtual Machine without any consequences because clearly the VM does not have a real (as in physical) i8042 either, right?

i8042prt.sys is just a (legacy) name... I would have given it a different name: e.g.: inputprt.sys. But Microsoft [probably due to backwards compatibility] stuck to the i8042prt.sys name since NT 3.5.
[a KB Article from back then mentions the file. But it could be even older than that.]

Again, I can quote an old part of a previous
post:
"No, they stopped putting PS/2 keyboards into laptops long ago, the same goes for the trackpad it may use the same PS/2 ports like the PS/2 mouses once did, but it's clearly not a PS/2 device, right? What you see there is just a ps/2 emulation by the EC. Much like "native" IDE support for SATA-AHCI devices nowadays"

Furthermore, there's even a CPU mode for USB-PS2 emulation, it`s called SMM
and I quote:

"Some uses of SMM are:
* Emulate motherboard hardware that is unimplemented or buggy.
* Emulate a PS/2 mouse or keyboard by converting the messages from USB versions of those peripherals to the messages that would have been generated had PS/2 versions of such hardware been connected."

So as I said, you can nowadays just about emulate every device in software.
Be it PS/2 or IDE (on top of AHCI). I repeat it's all just "emulation" of old hardware with new hardware. There's simply no way of connection a PS/2 keyboard to the matrix scan connector inside the laptop. Or a ATA harddrive to an SATA link which is accessed by the OS through the 0x1f0 ATA ports.

BTW: Since you are so upset. Have you looked at the Hardware "resources" in the driver manager of your Touchpad. You would be surprised... Apparently it needs only IRQ 12 which is odd. Since the it would only register if a event [button press/release, movement] happened or not and there's would be no data about the buttons or pointer position if this would be true.

 

Who cares?

 

Actually, I'm quite enjoying this.

 

...i think i've seen wittynorsemen get in a argument in every single thread stemming from his arrogant tone... just give it a rest witty... get a hobby

 

LOL Arrogance is part of my "MO," I am an INTJ. By the way I have lots of hobbies, being right just happens to be one of them.

 

Does anyone here have a HDX 16 laptop? If so, can anyone take measurements? The HDX16 guys have done the backlit keyboard upgrade but the only thing is that it's not chiclet style. It's looks similar in shape/layout to ours only used on a 16" laptop. http://forum.notebookreview.com/hp-envy-hdx/419998-hdx-16-backlit-keyboard-upgrade.html

 

I would be very grateful if someone could just provide the multimeter voltage readouts from the battery pins on their dv7 reading say left to right with the larger pins on the right hand side. Thanks in advance.

 

Could someone tell me the Display Part Number for the DV7-6xxx 1080P display? I have found several numbers in this post. 1 That doesn't work and another as unavailable. I've also found that it seems people are talking about a couple different screens but I may be misunderstanding things. I just need the Part Number for a Nice (deep blacks) 1080p Swap-able screen (relatively plug and play) Thanks!

 

One screen that has been sucessfully tried is the AUO B173HW01.

 

I'm going to try this one I think (V.5 I believe i've read is the best option.) I would ask your opinion on the quality and color but I see you own a DV6 I still haven't decided if I made the right choice (DV6/DV7) the size is a bit big but its also very nice. Audio is great and lots of screen space and storage... But finding cases and actually taking it places can be a pain!

( AUO 17.3" B173HW01 V.5 0A For HP Connect Left HD Laptop LCD Panel | eBay )

Can't decide if I want to do it before or after i move in 2 weeks (probably after)

Anyways

Thanks again.

 

I was just wondering if the I was trying to replace my DV6 Screen with the 1080p, when I order the part 656805-001 which shows up as "Display Cable Kit - ALU FHD" and costs $60, if that includes cable and display, cause that's a lot just for cable, no? If it has display that's really cheap compared to getting a laptop with it...which is too good to be true?

 

It's just the cable, I think.

 

It's just the cable. When I ordered mine though, it was around $30-40, os it looks like they raised the price.

 

Just a quick question as I'm thinking of buying one of these.

Looking at the manual, adding a 2nd HD (or swapping out the HD it comes with to the 2nd bay and putting an SSD in the first bay) looks pretty easy. I'm comfortable with basic modifications but don't like tearing out the guts of a laptop. Am I correct in thinking that it's pretty much just:

- Remove the battery
- Remove the service cover
- You can then access both HD bays?

 

yes, its that easy. Remember you need to buy a second hard drive cable. Google second hard drive cable dv7tqe and you will find it. You then put in your second hard drive, and route the cable through the provided places in the laptop and plug 'er in.

 

hey guys the new envy seems like it has the same exact keyboard, just a few of the function buttons are different, but check this out


HP Envy 15 and 17 (2011) - Engadget Galleries

 

Also has ayone tried this one yet?

New HP DV7-4000 US Backlit Keyboard Black 9Z.N4DBQ.101 | eBay

 

Do you think this could plop down into a DV6? Looks like the exact same keyboard (minus some volume buttons) but with backlighting. Very tempting...

 

The 'pin count' on the touchpads lighting cable is 5 on my dv6z, might wanna double check the 6 count on the T model. I ordered a hp envy 17 keyboard off ebay because it has english and russian letters, so when it gets here ill report back.

 

Looks like it's possible, but you would have to find an owner to get positive measurements. It also looks like the keyboard has a 3/4" or so bezel in silver, so that would look a little weird on a dark umber laptop.

 

I have a silver so its no problem to me.

 

any update on the illuminated keyboard?

 

Has anyone tried out the envy keyboards???

 

Anyone know what widget/gadget that is displaying CPU, memory, HD, battery, etc? Looks cool.

 

You might want to update the OP. The link for the display cable is down.

 

Yeah I second that, I'd like to advise of some programs that would show me my system stats in real time

 

If you wipe the HDD on arrival and do a clean install; do you still have any HP utilities? Are you just using a retail version of Windows 7?

I've heard the bloatware argument many times, but I do see much of that. Things like Bing Bar, sure uninstall it. But on past machines some of the HP software was either necessary or highly recommended.

HP provides the software necessary to play Blu-rays out of the box. Clean installs wouldn't have that. On the old DV7 they used custom proprietary software which was actually really good. It included a multi-thread compatible video converter, etc. This DV7 only had Cyberlink PowerDVD 10, which I seriously do not like.

I also have the HP Support Assistant, which I DO NOT run on system startup along with other things considered bloatware to me; such as Adobe Acrobat Reader.

As a result my system boot is less than 20 seconds ON A HDD!
My point being, of course; that HP Support Assistant has my serial number; support numbers, and even a direct chat system with premium/ENVY support.
(DV7 Quad Editions qualify for this support)

Finally HPSA offers updates to nearly everything on my computer.
This recent run included:
Intel WiFi Drivers
HDD free fall sensor drivers
HP notebook system BIOS update (Intel Processors)
Touchpad drivers
USB 3.0 drivers
Realtek (Ethernet) driver
Intel RST driver: (support for SSD cache/RAID configs)
IDT Audio driver (driver underneath the Beats software)
On-screen display
Power manager utility
Cyberlink PowerDVD 10 (oh joy)
AMD switchable graphics driver (the only way to safely update the CCC)
---
It might be possible to download these without HPSA.
Most of the time updates may even be unnecessary unless something is actually going wrong.
But I'd wager if you needed any of these things, hunting it down would be much harder than just using this utility.

It'd be like getting updates for a custom PC, but not knowing who made any of the components.

That said I'd like an SSD someday.. but I don't want to rebuy Windows or anything else already on this HDD. This probably means waiting until I can afford a big enough SSD to do a restore system image onto. Excluding personal files roughly 256 GB with all the games installed. At todays price that's more than half the cost of a new computer similar to mine.

So I wait.

 

Rainmeter, Google, or Youtube it.
It's awesome.

 

Maybe, possibly, instead of the ENVY backlit keyboard we could use another dv6 model keyboard?

They seem to look similar.

 

Yeah, it's called Computer Status, I use it all the time, it's great, it has a built in radio (British channels) and I personally like the fact that you can empty the Recycle Bin straight from the Gadget.

I'm not sure if I can post links or not, but since Microsoft retired the Windows Live Gallery, it's kinda hard to find, but here's a link.

Has anyone made a guide on how to replace an LCD in the DV7 yet?

 

Thanks for the post Busyboy.

Does anyone have any more information about whether the dv7t-4000 display cable is compatible? I am in the exact same situation, I may or may not attempt it myself, but I was wondering if anyone has had success with a display upgrade on a dv6t-3000.
