Hello! My ProBook 4540s was working fine until a half hour ago, when I unplugged it to move it and then attempted to plug it back in, and it stopped charging. When plugging in the power cord (that came with the ProBook when I bought it around 18 months ago), the light above the power jack (and no other lights) flashes white 9 times. I've tried following this fix I found on Google:
1. Turn off the notebook
2. remove the battery
3. remove the charging adapter
4. press + hold the power button for 40 seconds
5. insert the charging adaptor only
6. press the power button
and it supposedly continues but I get stuck at this point, because even plugged in, my ProBook won't start up without the battery in also. Is this a know problem/is there a fix for this?
