I'm very frustrated
I havea serious problem with my G510 i7 4700MQ .
When i plug the power adapter the cpu frequency is set 798 Mhz
When i UNplug the power adapter i can reach maximum 2.4 Ghz
Obvisously i cannot get turbo 3.4Ghz at all.
Graphics adapter frequency is also drops to 200 Mhz when i plug the power adapter.
What is going on ?
Is there a fix ..or is it a buggy notebook ?
My bios version is 3.05 and i know that the newer version is 3.09 but bios update is only available in Windows 8.
I've got windows 7
intel processor diagnostic tool shows FAILED when accessing cpu frequency
Solved! Go to Solution.

Totally unbelievable . The problem was caused be a universal power adapter giving about 75-80 Watts .. i tested another one rated 95 Watts...but if you want to use a universal adapter you really want a big thing..135 Watts !!!
