Question A power spike killed my battery... or is it the power supply

[Balrog49]

It's a Dell Precision M3800 laptop with a 130w power supply. The battery is showing 90% capacity in HWinfo. There were lightning storms overnight and the charge went from 100% to 0%. Now it won't charge at all. Should I replace the battery and/or the power supply?

Take the battery out and plug the charger in, does the laptop even power on or try to? If so probably just a bad battery.

If not, Well could be the charger, is also could be the charging circuit in the laptop its self, you wont really know until you try another adapter or test your existing one with a volt meter.

Good Luck!
