Background
My old laptop was bought ten years ago. I had never changed the thermal paste between its CPU and its fan. As a result, it had been getting hot during my online tutorials.

Main ideas
- – Ideal energy range for storage: 40%–80%
- The biggest enemy of electronic parts is heat .
- Avoid overchanging and unplug AC adapter when charging is complete. In particular, don’t leave a fully charged laptop connected to power supply. This can reduce the lifespan of the battery.
- Avoid deep discharges: recharge the laptop battery when its enery level drops to 40%.
- Reduce unnecessary programs running in background.
- If your hardware vendor supports Linux drivers for batteries, set the charging
thershold to 80%.
- Some Lenovo Thinkpads can benefit from those drivers.
- Other vendors like Fujitsu offers such drives for M$ Windows only.

Problem
Two months ago, the Win* 10 installed on my old laptop crashed with
