Specs: Windows 7, intel core i5 2.53ghz
Bought a manufacturer refurbised hp dm4 laptop.Jjust trying it out when i noticed, the screen darks out when not in use for a while which is normal but the problem is, onthe right hand lower corner i can see a patch of light still coming through when the entire screen is supposed to be blacked out until i begin using the pc again. Is this a major problem?, should i return it? will the will the screenlast or is it going bad.is it a screen setting, need help, only have two days to return it.

The light you can see is coming from the back-light which should turn off when the power saving mode clicks in the screen goes blank.

I would consider sending it back as a simple fault like that could be indicative of more serious faults that you dont know about yet.

Thanks, I realized it as well only minutes before i recieved your message. The back light is actually the hp symbol light at the back. To be clear of what you are saying, is this normal, or is it a minnor problem that may not necessarily have major consequences. Note i bought pc in the USA and live in the Caribbean therefore it will cost me to send it back and ireally need a pc presently.

It is not normal but it is only a minor problem providing that is the only problem.

The back light is either and an array of LEDs or a Cold Cathode Florescent Tube depending on how old it is. The fact the it illuminates the HP Symbol is just incidental to its main purpose of proving light so that you can see the screen - Liquid Crystals do not provide any light of there own. If the back light fails you will see nothing and it could have a major repair job. on you hands.

I must apologise beause i am a novice. I was incorrect in statingthat when the pc goes to sleep ican faintly see the light. the truth is it does notshow when the pc is in sleep mode. I put it in slep mode and did not see the light. the only time i would see the light faintly that is,more like a glow is when i am notusing the pc for awhile and the screen darkens. when the screen darkens the symbol light remains on so i faintly see the glow exaxtly where it it.Note the pc is not in power save mode. I have not used the power save mode yet
