Charging of laptop while shut down may cause the corruption of operating system. While shut down battery level will store in the memory and in the shut down mode, if you are charging, it will store in another memory location. After that if you are switch on the system, it will compare both values. If both are not equal, it may be corrupt the operating system. I had affected by this. It wont happen in all times ..Once happened for me after that for knowing purpose i did the same for three more times.. But not the same result. Better to save laptop life, please dint charge while shut down

To partially clear computer RAM memory, close some programs
that are currently running. In Windows, right-click on any program in
the task bar and choose the "Close" option. That will free up the memory
that was used by the program. Even if you close every program running
on the task bar, a big chunk of memory is taken up by the operating
system. The RAM used by the operating system cannot be cleared without
shutting down the system.
To clear computer RAM memory totally, you have to shut down
the system. In Windows, click on the Start Menu and click the "Shut
Down" option. Unix and Linux have similar options. When this process is
complete, all RAM will be cleared.
If you are somewhat impatient, turn off the computer by
pressing the power button on the computer. This is slightly quicker than
the previous step.
If you are very impatient, unplug the power cord of the
computer. If it is a laptop, disconnect the battery as well. The
computer's RAM memory will be cleared immediately upon the power source
being disconnected. This method of shutting down the computer usually
causes corruption or some other problem when the operating system is
booted up again.
