When you say inbuilt battery you mean the rechargeable big battery or the little motherboard cmos battery shaped like a coin?

[harrison96]

the rechargeable big battery. just unscrewed it and left it out for a second then put it back in

Hey bud To be safe put your laptop in sleep mode it does not harm the laptop and it will lessen the likelyhood of corrupting any drivers or bios. Cheers.
