My hp dv2000 won't turn on, when i press the on button, all the led lights come on and so does the power led. the hard drive led flashes for 3 times..and then there is no response...just a blank screen. however, the laptop does turn on at times..runs smoothly..i mean it's not slow or anything..it works perfectly. turning on seems to be its only problem :( somebody help plz! :(
Hello Ayesha07,
Older Laptops can get lots of dust inside from the fan system designed to cool it. You may have a bad connection between your main board and the display. I have seen that cause eratic behavior on some systems. Since you mentioned that it does work from time to time normally, I would be more inclined to think you may have some problems with the lcd display..When it does come on, have you moved the display around ( meaning open and almost close the cover) to see if the display fails to work when you do that? As I mentioned earlier, you could have a signifiacant dust buildup inside the system and dust tends to cause intermittent shorts to the circuitry which may manifest itself as sporadic behavior. If and when the system comes up, I would strongly encourage you to create back up copies onto cd's/dvs's or an external usb drive so that you don't lose it if your laptop dies for good. Hope this helps a little.. Good Luck !
Good question... If you buy a can can of clean dry pressurized air ( sold in most electronic supply stores) ..you may be able to shoot that air thru various ports on your laptop and get the bulk of dust out. You'd be amazed at how much dust builds up on everything inside.. .. I don't recommend you try to separate the covers to access everything inside because of all the small screws involved. It can be difficult to reassemble things if you do get it all lined up and all screws back in the same location they came from..... ( you can try that if you feel confident you will be able to reassemble it correctly) everything has to line up just right and you may have different sized screws so you'll have to be very thorough on where each one goes.. anyway.. you may get lucky and dislodge the dust by blowing it thru the cd/dvd burner opening or any and all vents openings. Its a hit or miss thing.. and I do hope that works for you.. Good Luck ...

Usually answered in minutes!
but what exactly is wrong with it? power supply? hard drive? motherboard? i should atleast have some idea as to what exactly is wrong and why it's doing this?
but if it's the hard drive..is it 'normal' for the laptop to turn on occasionally and work as if nothing's wrong with it?
Thanks a lot rickzilla for your help :) but i have a question..u said significant dust build up may also cause such erratic behavior..so if i clean the dust (somehow) will my laptop go back to how it was turning on before? or is this a problem that is hard to resolve? and to answer your question..i don't think it's the lcd display..because i closed the lid and opened it to test the display..and it worked fine.
