Hi,
I have 2 Dell 5521 laptops that have been there for a while.
you would be playin a game at a decent performance when all of a sudden, performance drops to the point where game is constantly stuttering, low fps and unplayable.
i tried to followbthe case up and finally noticed the below:
- while the performance was bad, i went to task manager performance tab, and to my surprise, CPU was at a very low value, someting like 0.6Ghz or so
I unplugged the adapter and boom, went up to 2.x, game was good again
i could reproduce this issue almost everytime i tried it
my 1st though was defective adapter so i swapped the adapters, problem remained on the same laptop.
i then noticed battery was sometimes discharging instead of charging, so i removed the battery and connected the laptop to UPS. laptop now loses power randomly (turns off) while on adapter power.
I am now almost sure something on the mainboard is not working properly. if it was a desktop ill start with the power supply but with a laptop, im confused.
appreciate ur feedback in case uve faced sthg similar and was able to troubleshoot.
thanks
