Laptop Seriously under performing... I'm stumped

Hi all, I have a laptop that has:

windows 10 64 bit
Intel core i5 560 M
4 gigs of DDR3 @ 525MHZ
Generic Intel HD Graphics

It used to work well on windows 7, then it underwent a OS switch to Ubuntu, then another OS switch to windows 10. But, it slowed down, to the point of it performs worse than 94% of all budget phones and tablets on 3D mark... so I think something is wrong here.

Drivers are up to date, hard drive is not fragmented, registry has been cleaned, high performance power settings are on, etc, etc. I have no idea whats going on. Any ideas? Thank you all so much!
 
Solution
If you have a bad battery or charger, you might have to replace it. Some laptops will automatically downclock the CPU when they sense the battery or charger has failed .

The CPU clock speed is the same as factory defaults, but thanks for that suggestion!
