Hi!
Two laptop stopped with a same problem at a same day. No power, dead. I have bin investigated, that input dc flow stopped at the first mosfet. I can force the power to flow in, an the laptop works well, except no battery charge. BQ735 changed. Battery changed, still the same. Power in disabled. Mosfets not sorted.
If i plug in DC, a small capacitor enables power to flow in. After the cap is charged, (and everything is ok) the system enables power in. For a few milliseconds, battery charging voltage is rising. Then stop all, system power disabled.
Any idea? Schematic have One?
Thx
