Hey guys.

I havent got my PSP hacked or anything yet so this is just a normal question.

Ive just had to get a new battery for my PSP as the one it came with (ebay buy) didnt work. Anyway now I play it I get the battery low warning at about 40% and the PSP gets put into sleep mode. Is there anyway to sort this out, I did have a quick look but couldnt see a setting for it.
