The computer will power on but will not light up monitor internal or external. I had this problem on an acer aspire and had to replace the mobo. Is this, possibly, a similar scenario?
We had this problem several times, even sent it back for service when it was under service plan. It was fine on arrival for service. The "non-techie" solution we came up with... pop the battery... the key series in the book doesn't work, hard reboot doesn't work...unplug doesn't work... the only thing they did during the shipping process was removed the battery so we tried that and it seems to work every time.
I would think so, because you cant get display on external I would guess the video board is bad

the very first thing that u can try is that try it with the different ac adaptor and the battery and try it with the differnt ac aaaadaptor and still it doesnt then wahat u said is that u can hear the sound of the fan and the disk is trying to read but u cannnot see anything on the screen adn all u need to clearify is that if the computer is actually running or not and if it is working then what u can do is that connect the external monitor and then try and turn on the laptop and if u get a good display in te external monitor then definately replace the lcd screen and also what u can try is that try and reboot the computer in the safe mode and if turns on and u can see the display in the screen then do the system restore and it will be fine.......and as u said that u get a choppy sound from the fan then what u can do is that try and clean the fan from the back or by opening it......anbd it will not get any sound from the fan......good luck....

Remove the memory from your unit - power it up it should beep if full communication is still happening across your m/board. No beeps you board has died. if it beeps and your using two diffent memory modules just fitt one leave the battery out and power it up = if no display pull power swap out the memory and try again. if display occurrs you have a defective memory module - throw that failed unit away

Hello,
The charger is functioning well. There are still two possible reasons why your computer is not turning on. 1. The battery, 2. The computer itself.
What you need to do is to isolate the problem.
Here's what you can do to isolate the problem.
1. Remove the battery from the computer.
2. Turn on the computer using the cord. Remember not to put back the battery yet. Just the cable and the computer connected. If the computer turns on, then, you need to replace the battery.
3. If it still not turning on by using the cord alone. Try to wiggle the cord to check whether it's loose or not. Check if there are some signs of power on the computer. If there is a power like lights lit in the computer, then, it's the computer that's having the problem. You need to bring it to a technician if that's the situation.
Please let me know if there are any development after doing the troubleshooting above so that I can get back to you if you need my help.
Thank you for using fixya.com

Hi,
If you see power lights but nothing appears on the screen, it could be a "POST" (Power-on Self Test) problem or simply LCD problem.
Here are some steps that you can try. One of these may work on your case.
1. Remove the battery and the ac adapter then press the power button for at least 20 seconds to drain electric charges left on the system. (You may need to repeat this step to get it work.)
2. If above step doesn't work, try to plug in an external monitor and see if you get display from the external monitor.
3. If you get display from the external monitor, I'm sure your having problem with the LCD components. In this case, check and replace faulty LCD backlight, LCD cable or LCD inverter. The LCD inverter is often a culprit.
4. Try to reinsert the memory module/s (RAM) of the unit, try using one RAM at a time to see if it works. A faulty RAM will cause the laptop not to POST.
5. If reinserting the RAM doesn't help, most likely your motherboard needs to be replaced.
Hope this helps.
