Closing/reopening lid or rebooting causes problems

[kunalashar]

Sometimes when I close the lid of my T60p and reopen it after a while things go very wrong, and I can't seem to isolate the causes.

At other times, I see the same weird behavior when reboot the machine.

Here's what happens (sometimes after I reopen the lid, sometimes after I reboot):

1. Cursor movement becomes erratic. The cursor seems to pause/stop and restart moving every couple of seconds. This doesn't go away until I reboot the system. Nothing seems to be hogging the CPU/memory resources in Task Manager.

2. If nothing was connected to my USB port, such as a mouse or a thumbdrive, then nothing I connect afterward to any USB port works until I reboot the system. For example, without the optical mouse connected, I close the lid of the T60p, and reopen it after a while; I connect the mouse... nothing. The mouse doesn't even get powered up, indicating that the USB port isn't receiving any power.

3. All network connectivity is lost. This typically happens *after* I reboot (after the mouse or USB port or network have been acting up). Both the wireless and ethernet connections show as Connected, but the send/receive status of the wireless is frozen at Send 0 bytes, Receive 3 bytes, and the send/receive status of the ethernet is frozen at Send 0 bytes, Receive 0 bytes. I cannot disable or repair the connections. When I try to repair them, the "Disabling..." window opens up and then hangs interminably. The only solution is to reboot.

4. The ThinkVantage Radio shows as powered off, but I can't seem to turn it on, no matter what I do. When I try to power it on, it waits for a while, then again shows up as powered off.

The *only * thing that seems to work occasionally is to restore the system to an earlier point. In about 75% of restarts after a system restore, the machine seems to behave normally. Of course, the moment I shut the lid or reboot, the problem reappears.

Unfortunately, system restore is not a solution or a workaround, because I have to install stuff on my machine that needs reboots. The most frustrating problem is that I lose everything I installed (up to a point) when I do a system restore.

Not closing the lid is not a solution either because I need to carry the laptop from one room/meeting to another.

I've tried reinstalling, uninstalling and upgrading all the system drivers, but none of them have had any effect.

Please help!

a quick and effective way to sort hardware failure from software problems is to do a system restore to factory preload..

of course, you'll need a spare HDD and a recovery CD set..
