I have a 2730 that had battery problems already a year ago.
Battery had a leak at this time and I just took it off and was able to use the 2730 while plugged into wall charger. Bought new battery, problem fixed.
NOW, I haven't used my 2730 for around 6 months and it doesn't turn on anymore.
No matter if it's plugged in via USB or wall charger. The red light turns on, but that's all, definitely can't turn it on.
Took out the battery like last time, but didn't change the situation.
Any help or hints, as I don't want to buy another battery for nothing, cause it doesn't seem to be the problem.
