I have Asus X550D , the problem is sometimes my laptop charging only at 75% then stop. The LED light also went off with "Plugged in , not charging". Then after for a while, it start charging again and went off at 90%. Then charging again until full.
And another problem is when plugged the charger at 80% above, it will says "Plugged in , not charging" but start charging only at 70%.
Please do try these troubleshooting steps that may help in identifying the issue.
- Remove the battery of your laptop then boot it up with just its AC adapter and see if it will stay on.
- Next is to test your AC adapter and see if it's supplying enough voltage or better yet try a different AC adapter that has the same voltage with yours.
- If these doesn't work do uninstall/reinstall "Microsoft acpi-compliant control method battery" from Device Manager.
- Last resort if all these will not work is to do a factory reset with your laptop.
