Check the duration for power under the 'screen' and customize it as you want. If the monitor remains blank, turn off the computer and continue troubleshooting. Some monitors do not have on-screen messages but instead use the lights to indicate no signal. When you disconnect the cable, instead of an on-screen message, the light turns amber, indicating that the monitor lost signal and is working properly, but is out of.

Hi,
My laptop is HP Pavillion dv4 1131tx.
I want to know that how many hours can I leave my laptop running continuously?
1.With lid open
2.With lid closed
and is it a good practice?
I read on some other forum that lcd of one's lapy stopped working after 4days of continuous stress. I dont have any work for keeping it on. I just have a thrill of keeping it on always and being online.
One more thing, I am a student.So, I dont want to take any risk,if any involved in this,although I have 4months warranty left.
Thanks in advance
Regards
