I have a Dell Latitude E7250 out of warranty that sometimes stops suddenly on battery:
- only when physically manipulated / moved
- battery installed, not empty
- happened at idle, so no heat problem and it is unlikely to be a software problem
- no warning or error, just instantly off
- no problem with powering up
The power / battery indicator also flashed battery error codes when the laptop was handled similarly with the AC adapter plugged in.
- BIOS reports battery is in excellent condition
- the AC adapter is the original Dell unit
- BIOS diagnostics reported no issues
The BIOS event log sometimes records a poorly descriptive error after these stops.
I did memory tests when I got it over a year ago, with no errors reported. The laptop has been generally reliable, but I'm afraid to handle it or move it around when you're doing something important. It is very annoying to experience downtime even when data loss is not a concern.
My best guess is that it is due to a contact problem, as it occurs when handling the laptop in a way that presses the exposed battery on the lower front part.
I don't notice anything wrong with the laptop battery contacts, and the battery does not appear damaged or swollen.
Is there a known problem with the E7250 or its battery? Any ideas on how to troubleshoot and fix this problem?
