I have issue with battery charging

When I charge the laptop 100 % (battery full )and shut down it (shut down not put it in sleep mode) I leave it shut down for may be one day or sometimes half day I found battery low or laptop not started at all due empty battery…

already I give it to JARIR SERVICE CENTER to check it (they take it more than one week) they try to fix it but they did nothing, and when they cannot repair it they said this is normal…
I said to them Please use your mind this is laptop I have to use it outside ( not use only in the home like desktop ) this is not normal !!!

Please I need to solve the issue as you can as possible …. This is the JARIR SERVICE CENTER customer information # 2045946
your feed me back highly important …
