That's a tough one. Have you changed anything like installed a new driver or updated the BIOS? Have you dusted it lately? How old is it?

i always install latest driver updates n what not, its actually a pretty good machine, never failed on me, i bought it in feb 2009, specs 2.4 ghz i5 quad core, 4 gb ram, battery though has failed, i ll get it replaced.

P.s. yes i ve dusted it, completely opened it and dusted it using air spray can, got proof images for that too :D, it runs rather quiet and smooth

Most would say a signal issue (other than power) with the graphics adapter or cable or even a dry solder connection.

i agree with the signal issue factor, i do had bad voltage in the recent past and which may have caused the problem, so i ll have to replace the charger if i m not wrong?

Well a bad connection or circuit device failure would have that effect by ohms law. That was a more in depth expression of the issue as it pertains to the way electronics works.

If it's not a BIOS or driver problem then, It definitively could be a voltage problem which could be narrowed down to one of the following cases:

  • You over-charge your battery by keeping your laptop plugged in a lot of time.

  • The voltage coming from your all outlet (in case the laptop is plugged in) is unstable (too high or too low) thus, causing problems with the laptop components which could affect the monitor as well.

  • Maybe that new battery you bought is defective (causing voltage problems as aforementioned)?

  • There could be a problem with your charger/charger cables causing over/under volt.

  • The power female socket inside your laptop might be having problems.

  • Maybe a few defective capacitors somewhere in the power circuit inside your laptop.

  • Another very famous problem is somewhere in the circuit that controls switching on/off your monitor when u open or close your laptop's screen. It's very common especially among Acer laptops (I personally had this problem before)

so how much will it cost me to get it fixed by HP(the official OEM)?

I don't really know exactly. It varies according to whichever case of the above. You could get in touch with HP support and let the support person give you a speculative range.

I'd recommend you go to your nearest computer repair shop however and ask them too. The problem might not be that big (as some of the aforementioned cases) and you could potentially fix it yourself or get it fixed at a much cheaper price.

generally they do not repair lap tops today because the cost and time of the repair is more then replacement cost of the computer .

everything is on board meaning nothing to unplug or plug in due to size limitations, because most company stopped produceing lap tops (PCs) in 2011 there is not a lot of replacment boards for lap top avalable ..

been there tried it with several places small repair and large cost to fix including bench fees if they can get parts about $450 cost to replace roughtly $298 to $350 .

LoL man! You should go to countries like China or Egypt. One Half of my family is Egyptian. When I'm there, I could literally get anything fixed at an almost-for-free price. I remember I fixed my similar laptop problem mentioned above for 20 L.E (That's like 3.6$ LoLz). The dude actually fixed it right in front of me in less than 30 mins. These people can hack their way around anything!

On another note, #FirstWorldProblems ;)
