Sooo, I spent a day trying to figure out why my fiancee's laptop wouldn't resume from standby mode. Also known as waking up from sleep mode. To put it more bluntly, the screen remains black after shutting the laptop, opening it, and hitting space bar or power button. The more curious user would also notice you could still "use" the machine if you do it blindly without seeing the screen.
It was a boggling thing and I almost just jumped right in and reinstalled windows, since I thought that would be the most obvious culprit. However, I was wrong and the fix is much less time consuming.
Basically, a new video driver got pushed out this year (2005) and it has a bug in it preventing this. The driver was published on Windows Update, Dell's Site, and Intel's site for downloading, so anyone who does even minor driver updates downloaded it thinking it was a better version. Here is some info about the video card:
- Intel (R) Graphics Controler
- Model 82845GM
- Sub-model 845GM
The affected driver version is 126.96.36.19920. You need to re-download and install the older version of 188.8.131.5289 to fix the problem. It is a hard to find download, but I located it here at Intel's site (win2k_xp147.exe). Basically, just download the file, run it, and click yes you want to replace a newer version of the driver with an old one. Note, this file is only for Windows 2000/XP and the bug likely doesn't affect any other operating systems.
Also, here is the text I found that lead me to the fix, but I don't remember the source web site, sorry.
