I have an out-of-warranty Dell Latitude E7250 which sometimes shuts down suddenly when on battery:
- only when being physically handled/moved
- battery installed, not empty
- has happened while idling, so no issue with heat and unlikely to be software issue
- no warning or error, just instantly off
- no problems powering back on
The power/battery indicator also has blinked battery error codes when the laptop has been handled similarly with the AC adapter plugged in.
Other notes:
- BIOS reports the battery is in excellent condition
- the AC adapter is the original Dell unit
- BIOS diagnostics have reported no problems
The BIOS event log sometimes registers a not-very-descriptive error after these shutdowns.
I ran memory tests when I got it over a year ago, with no errors reported. The laptop has been reliable in general, but I'm afraid to handle or move it when doing anything important. It is very inconvenient to experience shutdowns even when data loss is not a worry.
My best guess is that it is due to some contact issue, since it happens when handling the laptop in a way that presses on the exposed battery pack on the bottom front area.
I don't notice anything wrong with the laptop's battery contacts, and the battery pack does not appear damaged or bloated.
Is there any known issue with the E7250 or its battery pack? Any ideas how to troubleshoot and solve this?
