Hi
I bought a batterd A500+ with what seems to be a 1mb card for £2 but it has a red power light and caps lock light???Never seen that before.Also what things can i try and fix as it just keeps on reseting..It comes on a black screen and then white then resets and does it all over again.Oh and the power light keeps flashing also...
Cheers

Yes it is defo an A500+ but thats not my problem at the moment as it aint working lol.Right well i have removed the battery and had indeed started to leak juice out.It never seemed to bad from what i could see but i did re seat all the big chips.But i did notice on some of the small chips that look like mini roms there was some green colored corrosion on the pins which might be battery acid???
So what is a good way to clean it as from the looks of things it could be due to the battery but i aint no expert.The light flashes 11 times then resets..
Thanks
