Cannot resume from a standby

[jpullam]

I have an R51 running Windows XP Pro and last fall it stopped resuming from a standby. The only way I have been able to get going again after a standby is to hold the power button down until it shuts off and then reboot. I just installed System Update 3.0 in the hope that it would clean up something, but nothing changed.

Can anyone point me in the direction of something to do to track down the root problem?

you may have seen this answer before, but just in case...

press and hold down the blue-text "Fn" button at the lower left of your keyboard. this is the TP's way of knowing you want the system to wake up from suspend.

I wasn't asking for operating instructions. I've been using thinkpads for years.

I'm hoping that someone can offer some input on how to diagnose and get to the bottom of the problem. It just sits there consuming battery power and eventually runs down. I can't find any way to wake it up, and there are no error messages that I've been able to find.

I know the Fn key works because I can put it to sleep.

SORRY i was just trying to help.

Make sure your ram is matched.

If you have different sized ram or with different configurations of chips on the modules themselves, I've found that it WILL crash an R40 resuming from standby.

Similiar but not the same:

I have a T23 that I loaded a retail version of W2K on and it did the same thing, would suspend but not wake up. Never could figure out why so I ended up reloading it and it cured the problem. Fortunately mine had nothing on it except that so a reload was no biggie.

At this point I suspect that it is something about the software or registry. I discovered that if I try to hibernate, it freezes and reboots. I inhibited the auto reboot and the blue screen message ultimately told me that it is re-entering an error condition when it is already processing an error (or something like that). I figure that to rebuild is the only way out of this mess. There doesn't seem to be any diagnostic available to tell me what software module is failing.

Have you tried taking out a memory module, or are they both the same (if you have two)
