Hi,

I have an emachines M6807 and M6809 laptop and yesterday installed SP2 for XP home on both of them.

one works fine, the other has a problem which should be related to the update because it worked fine before.

Every time I unplug the laptop from the power, it completely freezes up and even task manager wont work. So I have to shut it off manually and start it up again.

Has anybody else experienced a problem like this? I have no idea what to check and where to look and windows doesnt seem to find any fault with itself.

Thanks in advance

Nina

Hello NinaE1 =)

When a laptop is unplugged from power, means now it will run on Battery.... and here the problem is happening.... ur system is freezing when u want it to run on battery power ??

now my one question,,, does the freeze happens only when system is running and u pulls out the power cable.... or if u start the system with battery support(power cable unplugged).... it freezes even then ??

that's weird indeed =\
I was thinking of the battary problem,,,, but it wud not run when started from battery, if it was a problem fo battery.... =|

now its more likely a BIOS problem..... may be the old BIOS is not compatible with SP2 yet.... so try upgrading ur BIOS to the latest version available at manufacturer's website.... or if u are already running the latest version, then i must say that either wait until ur laptop's manufacturer releases an updated BIOS comaptible with SP2.... or uninstall SP2 and wait until MS releases a Better SP2 which has less Bugs =\

First try to uninstall it using the method given here:

If above fails then try the Recovery Console method as described below:

This problem is due to a conflict with SP2 and the AMD PowerNow software that controls  speed for the AMD Athlon 64 Mobile processor.  

I had the same problem because prior to SP2, I had been running the Windows 2000 version of the AMD software, which allows for more user control over processor speed while on battery than the Windows XP version which operates automatically, with no option for user control.  Unfortunately, the removing the software and installing the latest version for Windows XP from the AMD website did not fix the problem.

It looks like the only solution is going to be uninstalling SP2!

I forgot to mention, I have an eMachines M6805 which is basically the same as your two models, mine has just a bit slower processor speed.  The lack of drivers from either AMD or eMachines is very frustrating, and users have been posting issues with the PowerNow software and Windows XP for a long time now.  This latest conflict with SP2 is only further hassle, and I hope that a new version of the drivers will be released very soon to fix these unacceptable problems.

sorry about not getting back to this sooner... was a little busy

I want to thank both of you for your replies. I finally got hold of emachines support (a little tricky when you live in the UK and got your laptops in the US) . They of course blame microsoft for not giving them time to support SP2 properly. However, I noticed they are advertising it on their own website too now but I don't suppose it fixes anything? Very annoying for sure and they weren't even able to tell me what causes it. So thank you for your post Mark, at least now I know what I am looking for and waiting for :)

I uninstalled SP2 on both laptops now after talking to emachines, the 6809 started developing some issues as well. What annoys me even more is that I installed it on a 2 year old laptop without any issues, and my 2 brand spanking new ones can't handle SP2.

Ah well, guess I will join the queue and wait. Thank you both for your replies. I hope it is ok with you that I split the points between you as I found both your answers helpful

Thanks again :)
