i had two laptop which is the same model and brought at the same date... but one of them whenever i plug in my charger, and open the internet explorer, it will immediately stop working, however when i take out the charger the internet explorer worked fine again... why is that so??

Hi, According to your description, the issue may related with the battery or motherboard. I suggest to perform these tests to troubleshoot the issue: 1 Logon with Safe Mode with networking, plug your charger to see if the same issue occurs. 2 Update drivers and BIOS to the latest version 3 Remove the battery, and plug the charger for test. Furthermore, you can contact laptop manufacturer to check if any hardware has issue. Thank you for your understanding and cooperation.
