The HP nx6125 / nx6115 and Windows 7

I'll just document the "bugs" with windows 7 64 bit edition running on the HP nx6125 - hopefully it'll save anyone else the bother of installing it only to find it doesn't work acceptably.

Here goes:

  • After a hybrid sleep/suspend, the screen brightness is fixed at minimum brightness, and won't adjust using control panel, the hotkeys, or the power adaptor. A reboot or power off then on again solves this. It is also solved by entering hibernate
  • After a suspend/hybrid sleep, the screen starts flickering badly after about 30 seconds, showing vertical lines and blocks in the bottom half of the screen. Closing and re-opening the monitor or changing screen modes does not help. Changing display adaptor drivers also does not help. A warm reboot or hibernate again fixes the issue.
  • The "mute" light stays on even when the system is powered off. After shutting down the computer, or entering hibernate, if the sound was muted before shutting down the light will stay lit even though the system is powered off. This runs down the battery fully within about a week. Pressing the mute button does not turn off the light, however removing and re-inserting the battery does. Starting the computer to show the bios setup screen also turns off the light.
  • After a suspend, the fingerprint reader sometimes no-longer works. I haven't tracked down the cause of this, but it appears to be a software timing bug where the fingerprint reader software tries to access the reader before it's ready.
  • Hibernate is unreliable. It works 6 out of 10 times in my trials with no extra programs or services running. The hibernate itself always succeeds, but resume often fails. Sometimes it freezes before the screen mode switch, and if this is the case you will be prompted to try again on the next boot, but retrying always fails in the same way. Sometimes it fails after the screen mode switch after running for a couple of seconds - usually it works fine for about 3 or 4 seconds, just long enough to type the start of your password, before freezing (no mouse movement and caps-lock lights don't change state). If it fails in the 2nd of the two ways, when you restart the computer you will be prompted to send a bluescreen error report (STOP 124).
  • No driver that I can find seems to support CPU frequency scaling, so battery life is seriously reduced.
  • The s-video out works, but when you disconnect the cable you will get screen corruption. To fix this, press the WIN+P (windows logo key and P) twice, followed by enter. You may need to do this up to 3 times. When you log out or switch user, you may need to do it again. A side effect of this workaround is often you can "loose" the mouse to the right of the screen, because windows thinks the svideo cable is still plugged in. Unfortunately, ATI has given up supporting the ATI x300 chipset on windows 7, so it looks like this issue wont be fixed. A reboot fully clears it.

After all those complaints, there is one positive thing:
It appears that Broadcoms x64 driver for the wireless card works considerably better than their 32 bit one. It stays connected to a wireless network for at least 2 hours before dropping out, and seems to have much greater sensitivity (it shows, and will connect to, networks at much greater range). The bug where a network would show in the networks list but connection attempts would always fail instantly seems to have been resolved. I can't comment on how well it works with the bluetooth because I removed the bluetooth module years back when it disrupted the wireless.

I hope the above will inform anyone planning on installing Windows 7 on this now pretty old laptop. If anyone knows any fixes\workarounds to the above, I would be very grateful!

EDIT: As mentioned in the comments, these nx6125's have a problem where the plastic around the keyboard peels off. The best solution I've found is to just pull it all off, and then use a fingernail to take the shiny grey paint off. That leaves a smooth black surface. If it's a bit sticky, use some nail varnish remover to take the paint remnants off. It looks way nicer like that than with all the bubbling paint. Also, if you're feeling adventurous, use a very thin layer of acrylic paint to change the colour. Use ~3 very thin coats - the paint I was using dried in about 10 minutes, so I got the whole job done in 30 minutes, and it looks way better.

Hello, If I use a Turion-based HP nx6125 with wall adapter only, shut down / restart daily and do not use sleep or hybernate, then it should be OK to install 64-bit Windows 7? I use a headphone which has volume roller in the cord.

I need 64-bit now, but Vista is so terrible, even with SP2, that I wish to avoid it if possible.

On the hardware side, what is the state of you nx6125's around-the-keyboard area? On my laptop the laminated teflon grey sheet started to form disgusting white blobs underside, probably the glue holding it decomposed and peeled off? It started just a month after the 1-year warranty expired and HP refused to fix it for free and the spare part price was shameless.

BTW, this surface degradation occurs on every nx6125 I have seen here in Hungary. It looks like this photo, but even worse for my notebook. You just can't carry a laptop this ugly to meetings, etc. and being relegated to a home desktop replacement role is a big reduction in use value. I considered suing HP, but consumer protection agency told me corporations have all the rights on their side in my country, so I better not...

Otherwise the notebook is great, 3xUSB, PCMCIA and Expresscard slot, Firewire, SVGA-out, integrated multi-card reader, good keyboard. On the other hand, the cheap clickety plastic trackpad buttons are a crime, even the Celeron versions were provided with silent hinge, rubberized buttons!

Thanks in advance, Sincerely: Tamas Feher from Hungary (etomcat at freemail dot hu)

You're right - most of the issues are related to power management, and therefore it should be fine when used as a desktop replacement.

It's certainly a big improvement in performance when compared to vista, and all the drivers are either built in or found by Windows update for the nx6125 (except the card reader, but I never use that, and windows does give a link to download the driver if you want it)

Mine has the plastic coating around the keyboard peeling off as well - I'm tempted to peel the whole thing off, sand it, and then paint it with thick glossy black paint.

I have one that worked on windows xp 64bit, but after i installed it, Windows 7 tells me I have to format the card so it can be used.

Thank you.

I have upgraded mine to 2gb and it works well perofrmance is similar to windows xp so no complaints there. Am really keen to get the card reader working tried previous drivers with no luck?

any help would be appreciated.

I cant get mine to work at all........any clues?

If you have problems with 2gb or larger card try this:
Modify the Registry an reboot

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\tifm21\Parameters]
"SDParam"=dword:00000001

I had problems with a 2gb card (not SD). After i modify the registry it works perfect.

Add this to you registry and the Cardreader works

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\tifm21\Parameters]
"SDParam"=dword:00000001

I had the same problem, now all SOLVED.

Install latest bios for nx6125 from HP web pages ( into WinXPpro section )
Install ATI driver ( for Vista ) from HP web pages.
And last one install QLB and QLBsecurity update ( quick launch button ) for Vista from HP web pages.

Now I can hibernate and sleep notebook without any problems :)

I found the flickering occurs with BIOS versions F.12 and F.13, one of which you must upgrade to in order to have "resume" even begin to work. Versions F.11 and earlier are broken:

I found only one particular video driver that cured the flickering:

http://h20000.www2.hp.com/bizsupport/TechSupport/SoftwareDescription.jsp...

The only bug remaining is that the screen comes back at minimum brightness but the system still thinks it is at maximum. This is cured by pressing brightness down [Fn][F9] (at which point the screen will become much brighter) followed by brightness up [Fn][F10].

I think you may have to have the Quicklaunch Buttons driver installed in order for the controls to work after resuming:

While you're there you can remove the yellow explanation mark next to the fingerprint scanner in the device manger:

HP has this update for the nx6125 which it list as essential but fails to say what it does:

Lastly, the driver for the Card Reader was given to me by some pop-up in Windows. (Was it the Windows Solution Center?)

Hi experienced the power problems as above but once disabled it works fine........with 512mb RAM it still performs ok but I wondered why it was limited to a total upgrade size of 2GB........possibly bios related. I wanted to upgrade to 4GB but wonder if this is possible.

Wifi works well..........as does most of the software in Windows 7.
Very interesting forum.........

Same issue with the released 32bit version Windows 7 Ultimate. Before I upgraded the BIOS sleep was even worst, but with the latest BIOS I'm getting the same sleep problems (and keyboard peel)

you should run powercfg /energy from an administrative command prompt to find issues drivers may be causing with sleep/etc.

install WINDOWS 7 HOME BASIC, not the ultimate, and all problems are solved!

Install WINDOWS 7 HOME BASIC and all problems are solved! my NX6125 works fine!

If you have standby problems with the finger print reader. Use this driver, it works perfect.
1. Go to http://support.asus.com/download/download.aspx?SLanguage=en-us
2. Under Select Product, choose Notebook.
3. Under Select Series, choose Drivers.
4. Under Models, choose Fingerprint.
5. Click Search.
6. When asked for the OS, select Windows 7 (for 32-bit) or Win 7 64 bit.
7. 4 files are found. Pick the Version V2.0.0.4 and select a download site.
8. Save the file to your hard drive.
9. Go to Biometric Devices in Control Panel and remove fingerprint data.
10. Uninstall Win7TS and any other Authentec programs (WBDI driver package or TrueSuite, for example) from Control Panel/Programs.
11. Reboot (usually automatic).
12. Install the new driver package and go to Display Manager and make sure the new driver is installed (version 2.0.0.4, dated August 2009).
13. Go to Biometric Devices to turn on the reader for Windows logon, and enrol your fingerprints.

I had got a dream to make my organization, nevertheless I did not have got enough of money to do this. Thank goodness my close mate told to use the home loans. Hence I took the commercial loan and realized my dream.
