📎 AI Summary:
The thread discusses an issue where a Toshiba Satellite C55-A laptop's screen turns off quickly after locking, despite being set to turn off after 25 minutes. The original poster notices the screen dims and then shuts off immediately upon locking, especially when using an external TV monitor. Contributors suggest that this behavior may be normal for Windows 8, and one user shares a personal experience where incompatible RAM caused similar problems, implying that hardware issues might also be a factor. Overall, the thread indicates that the rapid screen shutdown is common or can be related to hardware or software configurations.

I have a Toshiba laptop (Satellite C55-A). The screen is set to turn off after 25 minutes, but after I lock it, it shuts off in under a minute. Why?

If this computer was originaly windows Vista. You might have incompatible ram. Had a dell studio originaly with windows Vista. Tried windows 7 and windows 8.1 same problem. Changed the ram viola all gone. The ram that was in the computer was weird.

The Start and L keys are what I use to lock the laptop. The screen dims then shuts off. I use a TV as an additonal monitor and it says "No signal" until I move something around to get the screen back on.
