Hello,anyone can help me to verify the problem is ? I bought Compaq Presario F700 2years 4 months ago.
2 weeks ago when I was reading my email suddenly the screen black and since then whenever I pressed power button, I got on/off, on/off..., screen is totally black. I tried plug external monitor, RAM/HD reseated, but didn't change anything. I finally did diassembe job and found my fan quite clean only one hair and very minor dust in it. I adjust an improper connect original (beside the phone jack#2). I knew the RAM, HDD, power supply, battery, FAN are all OK. could it motherboard or GPU cause it? After I assembled the broken one the only differece I got except 3 green lights, SD-MS light on/off (blue colour), the WI-FI light on /off (blue but immediately turn orange colour,)the DVD light on/off (yellow colour).
I didn't see any thermal grease or thermal compound(silver stuff) sourand fan there. before it broken the touch pad was very hot comparing HP L2000 that my oldest one and thank God it still working for over 6 years.
