[SOLVED] CPU clock is so much lower than expected ?

[Help me plz.New]

So i am re-optimizing my mother's old laptop for like some online class while saving up enough money for a webcam and for it to arrive, but yesterday i realized that it is not running at full speed.It is a Compaq CQ40-630TU and it has Intel Dual-Core Pentium T4400 2,1Ghz, but the strange part is it only runs at 1.1-1.2Ghz most of the time ? Sometime i saw it running at 2100mhz for like 1 second in cpu-z or it might just be bugged because it only show when the app launched for 1 second ,after that it goes down 🙁
There are no relevant settings in the BIOS because that sucks 🙁

BIOS: Insyde H20 ver 3.5

It there any solution to at least boost it up or optimize the laptop as it is really slow with a 300mhz 2gb ddr2 RAM.
Pls help i can't deal with this anymore longer,it will take me like 2 more week to get the webcam so pls help
Power saving is off so it is having enough power, i even plug the charger in.

Give i a good cleaning.
Especially the exhaust vents. Blow air in the exhaust vents to remove blockages. You may need to clean the dust bunnies out of the fan after this.
Then set power options to High performance.
Monitor the temperatures to make sure it is not overheating. You may need to re-paste the CPU if temps get too high.

Do you mean T4300? T4400 is 2.2GHz. These are terrible CPUs for today because they only have 1MB of L2 cache, so most of the time the CPU is only effectively as fast as the RAM. Actually with only 2GB RAM the system today would mostly only be as fast as the disk because it would be swapping all of the time.

And this sounds like perfectly normal operation--before Intel processors had boost clocks, they reduced multiplier to 6x when idle. 6 x 200 = 1.2GHz minimum speed, and the T4300 had a 10.5 maximum multiplier (T4400 was 11) when under load. It should seldom need to run that fast if the disk light is always on--it's just waiting on the disk so why wait faster?

BTW the author of CPU-Z has stated that the single speed number reported is an average between all cores of multiple core CPUs, so may not actually represent the speed of any of the cores. Think of it as a ballpark number. And that ballpark sounds correct.
