Hi there, my cpu is not giving it's best, i only get 1.20 ghz on a 2.26ghz core 2 duo p8400 processor. What i think is that this issue is because of less power provided to my Dell Precision M6400, which i am using without battery (just like an desktop), my current charger is of Brand: LG Volt: 19.5 Ampere: 5.62 . Which means 110Watt but amazon and other e-commerce websites are selling a 210W AC adapter for my laptop. But that much watt are for charging + using laptop, while i only use i don't have battery installed, i tried disabling speed step but it give 1.70Ghz sometimes. Is there any issue if i provided 210watt? will it damage? or will it give best performance as it should give according to (users reviews).
First of all, temperature is normal according to softwares i've checked. Secondly, there is no power management driver (ACPI) option in my bios or provided by dell for my model, and last thing i've tried cpu-z it shows 1.2 or 1.3 Ghz
OS: Windows 7 home premimum x64 (as support by dell for my laptop ) i mean drivers are available.
i tried windows 10 and 8.1 too both showed 1.20 or rarely 1.22 ghz in the cpu speed (task manager)
the load i put is by using bluestacks mostly,
also cpu-z test can itself take laptop on it's limits without opening any thing. (Tested on other laptop)
