Laptop monitor shutting off after after a few minutes
Started a couple of days ago.Occasionally I can get it back for a few minutes by opening and closing the laptop - NOT always - wiring? or a fluke? Now I realize I no longer hear the fan kick on??? I'm using an old PC monitor til I sort this out. I have been in the habit of leaving the laptop on 24/7, have never dropped it, have shut down only to bring to office periodically. Laptop is about 3 years old.
Re: Laptop monitor shutting off after after a few minutes
I have exactly the same problem though I have a toshiba laptop, after 3 years of intensive use i think the lcd is gone, cos it has nothing to do with os as it did the same even when entering setup. btw i used to let it 247 on like you did !

In Windows 7 ,Try the Power Options in Control Panel. Set to High Performance, select Change Plan settings, set Sleep to never, select Advanced Power settings, scroll through the Advanced Power settings, set Sleep and Hibernate to Never and Power Buttons and Lid to Shut down. Always shut down and unplug the Laptop when not in use to prevent damage due to a power surge and a possible Fire hazard IF the battery malfunctions. Not to mention unnecessary wear on the components.
This is a tricky situation, any fluid that ends up inside can cause a cascade effect, hours, days, weeks and even months before the full efects are known. You could end up changing the screen and down the road face major failure in the motherboard. Under the circumstances I would consider a laptop replacement.
If your laptop appears to boot up and the hard disk LEDflashes, then the problem is probably a back light fault. This can be a faultyinverter or a faulty CCFL lamp.

Sometimes it di happen , specialy in most laptop which is being used more frequently and longer usage, the advisable use of a laptop is atleast 2 to 4 hours then shut it off and have cool down for 30 minutes to one hour then you can used it again, unless you got a support inclined base for laptop with support ventilating fan to help down minimize the heat accumulated during the usage.
have it check your video card with the proper technician, but first try to cool down your unit and try to open it again, and if still does'nt work then have it check by the service center
