I have a Lenovo W530 laptop that won't recognise the official charger (170 Watts).
The laptop battery will charge with an unofficial charger but only when powered off (because this charger is a lower wattage than recommended). When I turn the laptop on, the laptop runs off the battery but still won't recognise the official charger and will not run off the power supply or charge the battery while on.
I have:
Changed the fuse in the plug of the clover leaf cable.
Tested that power is being supplied to the end of the charging adapter of the official charger (tested with an electric screwdriver)
Tried a different official charger (not changed the clover leaf cable though - could that be a problem?) but the new power adapter didn't work either.
Power reset the laptop.
Removed the system battery from the laptop to do a proper power reset.
Updated the battery drivers.
Flight mode has been switched off and on.
There is a new BIOS update that I would like to try but I can't apply the update (from windows or prompt) without the laptop being plugged in.
I know it's risky, but I would like to try and do the BIOS update without the mains, but I can't seem to find a way to hoodwink the laptop into thinking it’s plugged in or doesn't need the mains for update.
Hope someone can help
Thanks
