I just bought a 'Like New' Dell Latitude E6410 laptop. I ran an initial diagnostics when I bought it, and everything seemed good.
Especially the battery. I ran the powercfg report on windows and found that the Design Capacity was about 72000 and the Last Full Charge capacity was 72000 which indicates that the battery was hardly used.
The first day went fine, by the end of the day I installed all drivers from the Dell website including Chipset firmware updates.
Since that moment, I cannot run the laptop on battery for long.
Sometimes it disconnects just after a minute of working.
It happens especially when I open games like Assassin's creed or open Firefox.
I don't think it is the temperature because when the AC is plugged in the laptop can run forever. It is only when it is on battery. And that only happened after installing the drivers.
Is there a possibility the chipset firmware updates are the culprits?
