T43p reboots unexpectedly: Urgent Help Needed!!!

Message

pointfielder · #1 Post by **pointfielder** » Mon Sep 22, 2008 4:07 pm

Hello Members,

Symptoms:
My T43p shutsdown and reboots itself while it is booting and when the
Windows XP Pro progress bar is going back and forth. It is
running XP Pro SP2. The machine runs fine in safe mode.

Background:
My USB port was giving excess power usage warning even when nothing
was connected, so I uninstalled and reinstalled the port. Ever since then this
random rebooting is occurring. I have also done a system restore to a
prior date but it hasn't helped.

I don't know if it is hardware or software problem. When I look at the
event viewer (in safe mode) for any error around the time of the unexpected
reboot, nothing is reported. Any help is greatly appreciated. My work is stuck
due to this.

Thanks,
Ravi

When in Safe Mode, go to Start --> Control Panel --> System --> Advanced Tab --> Startup and Recovery --> Settings .... and then uncheck "Automatically restart", then click "OK".

This should keep the system from restarting immediately when the failure occurs. Hopefully this will leave a BSOD and error message telling you which module or program is failing. This may then help you find the true cause of the failure.

Good luck.

I tried this. The system still restarts automatically and doesn't write any
events during the entire failed boot cycle. Is there a log file somewhere
that might be getting updated?

If you have any warranty left, send it to Ez Serv. I suspect a motherboard problem.

Just a hunch ... in safe mode uninstall the ATI video driver, then reboot. Let us know if that changes the symptoms.

Same symptom. Reboots while booting.

Do a Windows Repair using a XP CD.

If the machine works fine for hours on in safe mode, doesn't it point to
a software/driver problem, rather then a hardware problem?

From the background of the orig post, try disableing the usb ports in the bios and see if it boots normally.
Safe mode probably does not initialize them.

Disabling the usb ports didn't help!

I tried using recovery disks to get the machine to the factory state,
but that didn't install everything that came from the factory like
thinkvantage etc. Also, it didn't resolve the reboot problem.

So I am leaning towards a clean install of the XP from a disk.

Thanks everyone for the help.

If a clean re-install hasn't solved the re-boot issue, you most likely have a (serious) hardware problem...

I just finished trying a fresh install of windows XP that formatted my HD.
At the step of "Installing devices" it goes through about 60% and reboots.

Before I tried this fresh XP install, I used a linux Live CD to diagnose this problem
and it also rebooted when it was loading some acpi related driver.

Now, do I need to send this machine in or is there a way to fix the acpi issue?

If it's under warranty, I'd send it in. Tell Easyserv that you can't install an OS without the machine spontaneously rebooting.
