Slow CPU until i restart laptop

Hello,

I encountered a strange problem recently with my laptop. If I boot the laptop for the first time, CPU runs approximately on 1GHz, its supposed to run at 2,7 Ghz at maximum. However, if i restart laptop, everything runs perfectly. How can I solve this problem?

Assuming you're on a Windows machine...

Check if your power plan is configured correctly. It should be in high-performance mode. In control panel, search for power options. Once you're there, select "change plan settings" and find "processor power management" and select "maximum processor state" to 100%. After you do this, restart your system and see if it has fixed the problem. I know you're saying it works the way it's supposed to after a reboot anyway so you might have to shut it down after this and then boot it up to see if it is working properly.

Agree. What OS?

In reply to: Slow CPU until i restart laptop

I'm starting to run into weird issues like this but the story is that it usually involves an owner that didn't like Windows 8 or 10 and loaded 7 or another OS. The speed is setup on modern machines differently. For Windows it's in the Power Plan (for modern Windows, press Win+X and get to the Power Options. Take it's defaults and it should be fine. I've had to reset a few power plans so far.

As to the install of the OS, I find that many can't do that anymore. Mostly because drivers and apps for their machine are hard on folk. This is why I suggest most stick with the supplied factory OS.

Windows 10

In reply to: Agree. What OS?

I run Windows 10, which was installed as default OS. I tried different power plans, all had maximum cpu speed at 100%, i tried reseting bios to default... It should have something to do with boot options, because if i restart the laptop, cpu runs normally, it is slow only if i boot it after i turn it off.

So it's stock?

In reply to: Windows 10

You have a warranty issue. No new machine with W10 has done this.

I use this laptop for 5 months approximately, this problem, however, occured month ago. So you suggest sending it back to manufacturer to solve this problem?

There was a long discussion I can't find.

In reply to: 5 Months

And it turned out to be the CPU in one case and BIOS in another. Both would best be fixed by the maker.

I take it that a factory reset has been done and it's still bum. So yes, it's back to the maker.

Try dusting?

In reply to: Slow CPU until i restart laptop

I had a similar problem and cleaning out the device fixed it. I suggest checking for dust and making sure the cooling system is working

I've done that

In reply to: Try dusting?

I cleaned the laptop, nothing changed. If it was a cooling problem, it wouldn't be solved by restarting the laptop. CPU runs at max. 40% immediately, not after the laptop gets hot. Restart always solves it.
