Two years old samsung laptop with Windows 8.1 64 bit halts without notice or taking low battery action. I realized that it happens when it shows some 55% battery limit. It dies suddenly and immediatelly. I wonder if
- the problem is that battery charge level is incorrectly detected and in fact it is 0% already
- it dies though it has 55% yet.
One more thing - it occurs 15 minutes since I unplug the AC power cord. Thx
