The reset procedure actually is to disconnect the battery and the adapter. Then press and hold down the power button for 30 seconds. Then reconnect everything and try to reboot. Run a diagnostic procedure by tapping F12 immediately at boot. If it runs properly watch for any errors. That flashing amber light means a low battery charge. It is possible that the battery needs to be replaced or that the adapter is not charging the battery properly. If the adapter light stays on then a short is not likely. If possible try another Dell adapter. It is also possible that the DC jack is having problems and needs to be replaced. Least likely cause, the MB charging circuit is not working.

Hi there . don't worry its a simple issue . I had gone through this problem.initially i got frustrated cuz of it but when i troubleshoot it i found that there was a problem with my laptop's ram it may be bad but this happens in rare cases its best solution is just remove your ram and clean its terminal with rubber . And clean the inner terminals of the ram slot inside the laptop with some brush tools or something like that but be carefull . Now after cleaning put the ram back in. And tirn it on . Here you go.

4 is a memory failure. Unplug the system, remove or disconnect the battery and hold the power button for 30 sec. Remove and reinstall the memory module(s) -- then try powering up. If the same error arises, try one module at a time in each socket until you isolate the bad module (replace it) or the bad socket (replace the mainboard in that case).
