Solved! acer laptop wont work without main supply

[vinay_29]

I have a 1 year Acer aspire lap top but even though I have charged up to battery and it shows 100% it will not start just on battery and if I start it while its plugged in to the mains and then remove the mains lead it turns off immediately. Any ideas please.

If it in warranty? If it is contact Acer. If it's out of warranty buy another battery and try that. It may be a motherboard connection issue also but battery is the first thing to check.
