Please help? I have a Thinkpad W540 the charger can't work when the laptop is turned on (battery is not charged) but when the laptop is off, sleeps, hibernates the charger works and the battery is charged

The w540 needs a higher output charger is all. 90w isn't gonna cut it.

The charger I use is the original 6.75A

135W might still be lacking, try the 180W one

previously used 135W no problem and the battery charges normally when the laptop is used,

I have a W530, the original charger for that is (relatively) huge. It pumps out 170w at 8.5 amps. Charges whilst laptop is running or not.
