Hi Dhansiddh,

Is your computer working only with the AC Adapter?
Are you using the same battery shipped with the system?

I would recommend you to check the battery health and check the AC Adapter status in BIOS and drain the residual power from the laptop and see if it works.
Note: The battery life is largely determined by the number of times it is charged. After hundreds of charge and discharge cycles, batteries lose some charge capacity. That is, a battery can show a charged status but may maintain a reduced charge capacity.

Please reply if you have any questions.

Know good swaps are your friend -- this issue can be A/C adapter, Mobo, battery, bottom plastics (how hte battery sits in the machine) issues -- do a known good swap, even if you have to go to Best Buy to do it.

Hi

I talked again to the SAT people, they told me that it could be an AC adapter problem, because some laptops of the 7720 line use 130 W AC-adapter while mine is only 90 W. I dont know if that makes any sense, i also think is probably a motherboard issue.

Anyway, a technician will come if the problem is not finally caused by the AC-Adapter. I already tried to charge the laptop overnight,  actually i tried it 3 nights in a row, but nothing happened.

Thank you for help.

Well, the problem is already solved. It turned out that it was a motherboard problem. A Dell technician came here, changed the mobo in situ and now everything is fine.
