Hello!
Recently I noticed that my laptop battery was reaching the end of it's usable life, so thinking ahead I ordered a new (non-dell) one. After receiving and replacing the battery all seemed well, I ran the on-board Dell diagnostic and it stated that the battery health was 100% Yay! The sun started to shine so I undid my shoes, took off my clothes and ventured out into the great unknown that is my garden.
But alas, it was not to be, if the battery drops under 90% the laptop just cuts out. Bad battery right? But here's the catch: If I install the old battery all is well, if I run the new battery in safe mode all is well too. I got another (non-dell) replacement battery from the vendor and the problem remains the same. What's going on?
specs:
Dell Latitude E6520 running windows 7 professional 64bit SP1 (with I7-2720QM)
Chargers: 65W and 90W AC Adapter (+dock)
Old battery:
Dell (8700maH) Type: XV2VV
Replacement battery: (2x)
Samsung SDIDELL TVMVN (5200maH) Type: T54FJ, E5420
In short:
-Works fine with old battery, but health it around 50%
-New battery installed: will boot, shuts down after logging into windows, or if charger is taken out and battery level drops below ~90% Will boot and work if booted into safe mode. This is true for both replacement batteries.
-If old battery is reinstalled all is well again.
Tried resetting the powerplan to factory defaults, disabling power service, updating the bios, swapping chargers, using the dock to charge but nothing seems to make any difference so far.
Any ideas? Any additional information needed? I would really appreciate a hand with this.
Sincerely,
Maarten.
