Laptop screen stays black after sleep mode

Hi everyone, definite tech neophyte here. I have a Toshiba Satellite U305-S7446, Windows Vista 6.0 (service pack 2) 32-bit.

My new problem, as of late, is that when I put my computer on sleep mode, when I open the computer back up I can hear the computer come off sleep mode and the power button stops blinking and turns blue, meaning the computer is on. However, the screen remains black. The only thing I've been able to do is to manually shut off my computer by holding down the power button and restart the computer. I played around with the power options, but still have the same problem no matter how my computer is put to sleep.

I saw in one post it was due to drives being out of date, but I just checked for updates on my disk drives and all are up to date. Another post mentioned the BIOS, but I am so not fluent in computer language that I got lost. Is there someone that can walk me through this in plain English? I am terrible with computers, so I need very explicit instructions. Help!!

I think that unless there are more clues there is no reason to install drivers. There are known causes such as adding some mouse drivers or other apps but it appears there are no clues about that in your post.

Given the lack of details and the fact that drivers do not wear out, it may be time to backup your stuff and restore it to the factory condition.

Sleep mode

So what happens if you do NOT use sleep mode? What I mean is, if you disable sleep mode and use basic Windows shut down procedures, what is the effect? If all is normal, boot, shut down, etc. I would then suspect a system configuration issue and likely would follow Mr. Proffit's advice.

Re: sleep mode

I tried a system restore to a point before I had this problem. All is working correctly again, but will back up just in case.
