I use an intel i5-5200U 2.20GHZ CPU but it's speed is stuck at 0.48GHz. All my applications run slowly and no matter what i do, the cpu speed remains at 0.48GHz. i have searched everywhere for a solution but to no avial.

lots of possible fixes for this:

• one answer I can find is get an official charger for laptop - https://community.spiceworks.com/to...est-clock-speed-multiplier-5x-0-48-ghz-win-10
• check vents aren't clogged up with dust, might be an over heating issue.
• try updating bios
• try updating windows

what make/model laptop?

Are you running plugged in?
Performance is better than on battery.

Run hwmonitor.
If you see a max temperature of 100c. your processor is throttling because of heat.
Check your cooling airways and see that the cooler fan is running.
Possibly the cooler needs to be repasted.

As a counter intuitive fix, try setting the max performance in windows power management down from 100% to 95%
