hello I have a Toshiba A135-S4677 my issue is when the laptop is closed and I reopen it windows 7 will not wake up just a black screen,I have to reboot it every time.

I had this problem on an IBM R52. Never figured out how to fix it, just left it open all the time and made sure it never turned the screen off. I also had a bizarre problem where launching Messenger would cause it to lock up. Never figured these out though...installed a different OS on it that I needed for school. Will be putting 7 on my desktop though real soon.

make sure you have the proper chipset drivers installed. I had this problem once with an hp laptop in vista.
