laptop goes to sleep w/external monitor connected

by JBinSD / May 5, 2013 7:26 AM PDT

I recently hooked up an external monitor to my ASUS laptop (running Windows 7) and it's now going to sleep at times as I'm working on Word, viewing a video, or without me doing anything. I've changed the power settings, had the PC checked out at the shop, switched out the monitor and the power chord, and it will still go to sleep. It usually does it with several programs running (Quickbooks, Firefox, Word, Outlook, Itunes) at a time and late at night after it's been running all day. It often does it when I'm streaming video. I added RAM to it and that didn't help either. (It never goes to sleep like this if I'm using the laptop's monitor only.) Here are its specs:
The chip type: Mobile Intel (R) 4 series Express Chipset family
Adapter string: Mobile Intel (R) GMA 4500 M
Total available graphics memory: 1326 MB
Dedicated Video memory: 64 MB
System video memory: 0 MB
Shared system memory: 1262 MB

Last night just before it went to sleep I noticed I could hear the fan running and it sounded like it was working pretty hard.

Any help would be greatly appreciated.

I can't find the exact model but I'm finding many folk reporting "it's going to sleep" because the monitor shows such a message. What's really happening is the laptop shut down and the monitor shows a "going to sleep" message so let's move on.

Given the GMA I have to guess the age but let's check if you are using the canned air to clean every few months.

Laptop still going to sleep

Thanks for the reply, but I've tried the canned air inside the laptop and the PC still goes to sleep, usually after I start streaming video.

And I'm definitely sure it's just going to sleep and not powering down. I just hit the enter key to bring it back to life.

I think you need to see a shop or support.

Given the claims above I'd have to see the unit. I'd be checking all the sleep settings from BIOS or OS.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
