Windows 7: CPU at 100% after dropping laptop

CPU at 100% after dropping laptop

Hello. My Cpu stays at 100% after dropping it from my desk.

Now my cpu stays at 100%-80% and laptop is plugged it but no charging. I have read that this is some kind of protection in order to avoid damage to the laptop.
I think I might have damaged the charging cable.


Now I have ordered another charging cable from ebay but it will take a while before it arrives.

My laptop is almost unusable. Is there any way to fix it until the new cable comes?

I have tried ThrottleStop but I never understood how it works.

Thanks.

Dropping laptops is very often fatal. Damage occurs in the Hard Drive as they are very fragile. Screen damage can occur as well.

In a lot of cases it's cheaper to replace it with a new one as the cost of repairs often exceed the replacement cost.

Im pretty sure there is no other damage. When I unplug the cable the laptop works just fine. CPU goes down to normal usage. As soon as I plug it in the CPU goes to 100%. I have fixed it several times using ThrottleStop but I want a more reliable solution.

It's what is using the CPU it's worth checking the hard drive for errors that the main thing that could be damaged and 100% disk could be trying to read damaged bits

Im using a SSD. Do I still need to check for errors?

This happens because the power plan is set to use less CPU when on battery in order to save on time it can stay working.

If you believe it kinda works for you, then you could lower CPU % via power plan. It won't work out for you as a solution, but as a work around for the time being.

If you are unsure where it is located in settings:

Power Plan Options -> Change power plan settings -> advanced settings -> processor power management

You can go through the other settings there as well, you might want to do extra customisation there based on circumstances.


About SDD, eee the following is just my guess, but SDD isn't as fragile as HDD. Nevertheless, you can download SDD's manufacturer's tools in order to check its current condition. It won't be taking way much time for you to do that really, so do give it a check to be sure it's healthy.


I also recommend you taking a peek in so called "Resource Monitor" (should be accessible via Task Manager). It should have tabs for CPU/RAM/HDD/NETWORK.
You can use this tool to track down your components' activities, e.g. CPU may indicate where it is busy, whilst HDD/SDD would show if anything is being heavily read or written there at the moment of CPU being packed up with tasks.

Try to check if the processor power management is set to low on the power plan when plugged in.

You can also check if System Idle Process is peaking at 100%, you shouldn't worry about this.

Thank you @Acova and @RoasterMen.


I checked the processor power management and the minimum was set to 100. I set it to 0. Laptop working fine now.

You're very welcome!

Will someone locally get a punishment for this joke? xD
I don't think you or Windows set it to 100% there, neither laptop's fall would've done that.
Could be a virus/script's doing if none else was at it, but personally I've not come across such outcome even once in my lifetime...

Either way, I am glad to hear it's worked for you. Still, let the security means check your system for insurance.
Also, take care to not drop the laptop accidentally again. Best of luck there and Merry X-mas ;D

No, you can actually set the CPU Processor Power usage to 100% to maximize performance in exchange of heat. However, it may vary. :)
