acer aspire 5750 blinking lights, battery not recharging

[jurgendevisser]

I’ve found a post about my problem - but not the right solution.

Problem: the power-on button on the upper left corner and the battery- and power indicators on the front of the laptop will start blinking and the laptop will crash after a while.

I am able to recharge the battery - as long as I don't boot the laptop while recharging. When the battery is full, I can let the power connected and it will work. I can use the laptop using the battery (power adapter not connected)... but as soon as the battery is not full, I have to shut it down to recharge it first (or take the battery out and connect it to the power adapter).

I have 3 batteries, 2 new ones: same problem with each - so no 'end of life' battery problem here.

I am now running Win10 now - same problem as in win7.

I did fix something: the ground connector on the power in plug was disconnected / broken. Fixed it - but it did not fix the problem.

Anyone?

Count the number of times the lights blinks to gain the sequence, this should provide a clue, common feature of laptops.
