Re: charger

Hi Refaat1379,


Welcome to the Community Forums.


Make sure that you got an OEM original charger.


Others may fail to charge with same speed as the original charger as it may fall short of ac charger BIOS detection so charging without turning on the laptop may help. Another charger may say with same specifications but cable quality can be different too as you may have notice as same with charging our phones.


I hope this helps answer your query.
