lenovo ideapad 110 batary

Only 7 months old? Then it's still covered by the manufacturer's warranty so you should contact them to have it replaced or repaired free of charge.
 
Solution
That's tough - - I wouldn't have bought it new with only 6-months warranty - - I would have walked away and bought elsewhere.

Anyhow, no point banging on about it now.

Does the laptop work on mains power or not at all? No lights come on? Nothing?
