====== Dell inspiron 5537 battery "feature" ======
When **Dell Power Manager** is turned on, battery consumption on linux is almost on maximum - that means around 23W. When power manager is turned off, power consumption can be reduced (gpu turned off, wake on lan turned off, display brightness decreased, cpu clock speed reduced etc) to 10W. There is no linux power manager (but this applies to almost any notebook except few thinkpads).

Battery died out after aprox. 2.5 year - after battery was disassembled it looked like in one serial pair of two batteries died. Problem was that it does not meant rapid capacity drop, but instead rendered battery completely unusable. It looks like it is normal lifespan of that battery type (many people report sudden death of their battery pack on 5537).

=== overall dell inspiron 5537 usage report ===
  * when display brightness is not on min or max there is some high frequency noise coming out of it, it is not loud, but in quiet enviroment it distracts attention
  * when I started to use this notebook as mobile after aprox 2 years display started flickering (connector for LVDS cable on display side - when pressure is applied flickering vanish), change of cable did not fix flickering - need to resolder connector or change for new LCD.
  * plastic chassis is not bad, but wont last long under heavy-duty usage. Be little gentle to it if you want it to last.
