Laptop won't turn on.

[BoltBolts]

I installed an unlocked bios on my lenovo g580, and when I changed some settings to allocate more memory to the iGPU, it wouldnt boot up anymore. I just had a blank screen, but the fan ran and the screen turned on. So in a panic, I opened up the laptop and tried to reset the bios by shorting the RTC battery, however, I followed the wrong advice.

I shorted out the battery pins while the laptop was on, and that did not fix the issue. So I then turned it off and disconnected the AC and battery. Following some better advice, I shorted the RTC battery again and held the power button for a good 45 secs. Then when I plugged back in the power and tried to turn the laptop back on it didn't work.

Instead of the usual power LED turning on when I plug in the charger, it was blank, and only lights up after I press the power button. However this time, the fan didn't spin up and the screen didn't turn on. After around 5-6 seconds the power LED turns off again.

So I want to know if I ruined my motherboard by shorting out the RTC the wrong way...

If I can get the laptop to at least turn on again, I should be able to fix my bios.

Thoughts?

You may have damaged internal components of your laptop while while shorting the RTC battery. How ever the initial issue may have been caused by the BIOS. have you preformed any updates on your BIOS?

Sounds that way. If you did, electrical damage is exceedingly difficult to troubleshoot and repair. You would save yourself time and headache by replacing the board if this is the case.

If only I did more research and didn't panic.... Thanks for the thoughts guys, looks like I'll have to buy a new mobo.

And to hamperking, I installed an unlocked bios and messed around with a couple of settings. Little did I know I could've reset the bios by simply holding Win + B and flashing the default one...
