Laptop can charge, but doesnt turn on, charged it overnite and tryed to turn it on it still wont work plz help

Try opening your laptop so the motherboard is visible,try to check to button that is underneath the power button making sure that the ribbon is securely clipped in,if it is you may have a problem with the actual chip that turns the laptop on, if your 100% that the chip works, check the PSU,simple things like scratches on it can damage the power supply if there isn't any scratches, check the battery.

Hope this helps!

If you go to the Dell support site online and enter your service tag # , then search 'boot problem' or 'startup problem', you'll get specific troubleshooting instructions for your laptop.
Otherwise, here's a general troubleshooting article that may help you to diagnose the problem, and here's a somewhat dated but still very valid boot troubleshooter.

I hope this information allows you to resolve this issue. If you need further assistance, please post back with a comment to this thread.
