    Ok this laptop was for a customer of my dad the screen was damaged but when i connect it to a monitor it worked. It was too expensive for her so he gave it back now 2 days ago i bought it from her for cheap. But when i tried switching it on nothing happened no lights flashing nothing its like it is dead. I tried the battery on another computer and it works , the charger works , the RAM works , the hard drive also works. I only havent checked the processor. Any help of what the problem could be ?

    Check that the wires from the power switch reach the motherboard and firmly connect to it. If they do, then the motherboard may have failed.

    Ok i striped it and i started measuring where the voltage goes and while i was checking it i saw that one element was blown it is C252. Now i was wondering if any body can find a similar element to this that can work because i cant seem to find it any where ?

    how big is the componet? can you post a picture of it or email a picture of it so i can see what you have. yes it can cause laptop not to powerup as it could be shorting out.
