Windows 7: After closing laptop lid, can't get out of black screen

After closing laptop lid, can't get out of black screen

I left my laptop on and had to leave so I simply shut the lid down. About 2 hours later, I lifted the lid and got only a black screen. I moved the mouse around to get it to come on but it would not. After about 5 tries on holding down the button in which to start up my laptop or turn off in this case, it finally turned off then I was able to turn it on and all was fine. I held it down for about 15 seconds. So, question is why wouldn't my laptop become active again when I opened the lid, etc?

Here are some of my specs. Don't know if anyone needs it.

Model Number: Toshiba Satellite S875-S7240
Operating System: Windows 7 Home Premium 64-bit
Processor Brand: Intel
Processor Type: Intel Core i5-2450M Processor
Processor Speed: 2.50 GHz, 3 MB L3 Cache
System Ram: 6 GB
Hard Drive Size: 750 GB
Max. Memory Expansion: 16 GB

Once you left it on sitting idle for that much time a kind of permanent hibernation mode set in where powering it down was the only option you had available. When you know you won't get back to it within a short period of time you are far better simply shutting it down to start with. This is how many laptops work.

One of the main reasons would be conserving battery power. This is why the display will turn off after so long until touching the pad or moving any mouse you have plugged in so the battery charge will last longer. You have to be prepared for this type of situation with anything battery powered to begin with including netbooks, tablets, cell phones., smart phones, etc..

Okay, I understand. Thanks for the quick reply. It just freaked me out at first. One time I did close the lid but came back to it about 6 minutes later and it started right up. Again, thanks.

That's the thing about a good number of the more recent even Vista models seeing the same thing over what you might have run into about 10yrs. back. They kind of have their own shutdown/standby mode when not having a sleep or hibernation scheduled. After so long you have to power them down in order to power them up!

I see. I'm gonna also check my settings for power on and other things. What i want the computer to do. My other laptop has Vista. I just got this new one with Win7 so I have not looked at any differences as yet.

Besides the power plans or creating one in 7 the laptop itself likely has it's own automatic shutoff even if you set everything to the never turn off.

The problem I seem to have here despite a recent clean install of Windows and setting each plan plus the custom plan made default to never turn off the display I have to click the power options shortcut to change the constant default 20min. to never when first powering up or after any restart.

I already went through the guide here for seeing the custom plan made default in the registry but even that still sees the default 20min. annoyance return. For the laptop you have there however that would be by manufacturer's design as you would expect from just about any portable or hand held out at this time.

It also depends on where you have it set for closing the lid in Control Panel>Power Options. I set closing the lid Hibernate, others set it to Shut Down or Sleep. If it doesn't perform the correct choice then it needs further troubleshooting.

With some laptops you don't even any lid options available. One Toshiba Vista laptop and another HP 7 laptop can both be carried around with the lid down and be right there where you left off since the display remains on when going to carry them from one room to another.

It's not so much the make but particular model series where you may find different options available. With some when you lower the screen it will lock down while others have no lock at all. Some with lid button and others without.

There is a setting for doing Nothing when closing the lid, too.

I've seen that one as well. For leaving the laptop unattended while still on for a lengthy period of time with the screen down that would be one idea to try out. But if the laptop has a battery monitor it may still slip into the standby type mode on you there.
