Having problems with your Acer Aspire 4520-5582 Notebook ?

My acer 4520 can't do booting. There's only sound of the harddisk for 5 seconds and nothing happens. The light green is on but the screen is still black. Nothing happens even if I insert bootable disk. What's wrong?

Okay, Here's the deal..... I recently had the same problems with my friends' Acer Extensa laptop and here's what I did to fix it. I narrowed the issue down to two culprits 1. Overheating, 2. Defective Motherboard. I have fixed the problem but I takes time, patience and some technical ability which may not be available to some. :(\012(Swapping out the motherboard MAY fix the problem but if the defect is in the manufacturing process then the problems could return). Here's how I fixed it...\012\012While in the process of disassembly I noticed a small electrolytic capacitor that had seemingly broken off and had become wedged between the frame (very lucky! this gave me the clue I was looking for!). This made me think that it had broken off the motherboard. I proceeded to disassemble the laptop and found the location of the missing capacitor (there are two located right next to each other on the board) and was able to re solder the capacitor back onto the motherboard (could it be a manufacturing processing defect thats causing these to break loose? ). Mine was broken off due to what looked like bad solder joints. Your capacitors could still be attached but have weak solder connections. Also while i had access to the motherboard, I used the opportunity to clean and re apply the heat sink compound to the CPU and thoroughly clean the fan vents. I then reassembled the laptop and EVERYTHING has been running fine now for the last 3 days. Total time was about 4hrs and it cost NOTHING to repair. GOOD LUCK :)
