January 4, 2013Help my Dell laptop won't turn on I've done everything said from the internet
Dell laptops have issues with the power regulation chip. What you need to do is pull the back cover off and unplug both the main battery and the CMOS battery. You need to be very very careful removing the CMOS battery. Do not pull the battery out by the wires. I find it’s best to use a plastic pry tool of some form, whether it be a spudger, old credit card or some other thin semi-semi blunt plastic tool. If you rock the two sides back and forth then push out the connector down the center, it will come out. The CMOS battery looks like this: https://guide-images.cdn.ifixit.com/igi/rWTpWLLvSdZ36TQU.large Once you have both batteries unplugged, hold the power button for 60 seconds. Yes, really, 60 seconds. Plug both batteries back in and plug in the charger, then attempt to turn the laptop on. If all went well, the CPU fan should spin over a few times before the machine finally boots back up. Put the cover back on and you’re done. Source: I’ve been working in IT Support/Management with Dell as our main vendor for the last 12 years. More on reddit.com

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.

Ok, just tried it and still nothing. I can't get it to power on. All I get it the little power light up at the top by the battery life light. Nothing happens. Does that mean that I need a new system board?
