Intermittent slow running laptop

Rons_Son — Thu, 07 Nov 2024 19:39:06 GMT

I have an HP laptop running an11th Gen Intel® Core™ i7-1195G7 @ 2.90GHz. While it is very fast normally, it can suddenly slow down greatly to a point where it is not useable with most apps. When this happens I am eventually directed to the Intel Optane Memory and Storage Management app. Unfortunately, virtually non of the tabs actually work, so I resort to rebooting a number of times before the CPU fan stats working and things return to normal.

Any advice on this frustrating issue would be very welcome.

Thanks, Ron's Son

Hello Rons_Son,

Thank you for posting in Intel community Forum.

For me to further check this, please help provide the following details:

What is the complete model of the laptop?
When did you purchase this laptop?
Was it working fine before?
When did you start having this issue?
Did you change any settings before the issue started?
Is it overheating? Did you check the temperature?
You mention about the CPU fan, when the system starts getting slow. Did you check if the fan is still spinning?

If you have questions, please let us know. Thank you.

Best regards,

Michael L.

You used the phrase ..I am eventually directed to the Intel Optane Memory.. is this from an error that pops up on the screen, Windows Event Log, or something else. What OS are you running. Are you getting related errors in the Windows Event Logs?

BTW if you are running an SSD as most of us are, I have personally run afoul of this type of behavior from an SSD starting to have problems. The computer I'm typing this on used to have an SSD that would cause short freeze ups and then release, some times up to a minute or so. I spend a lot of time using Task Manager and Perfmon to try and track down CPU consuming processes, except by the time they would open up the event was over (because they wouldn't open up until the event was over). I used Msconfig to limit the number of items that would boot on start up, uninstalled some software all to no avail until I decided to switch out the SSD.

The boot on this computer is a traditional 2.5" SSD, on my other computer it's an M.2 but either way they are both flash memory with a finite life cycle for data writes. It's like the old adage about motorcycle riders, those that have gone down and those that will.

I have USB doc stations for both types and use the doc stations to clone my drives both to protect against catastrophic failures and for a series of full backups that go back years. OS's are relatively easy to replace but data and the final configuration of the OS, not so much.

If you are having SSD issues (and don't have a full backup) better to try and get a clone of the drive before it becomes so degraded you can't.

Thank you everybody. I used the HP helpdesk, who found some Intel updates that were not easily visible. A couple of re-boots later, and my i7 Intel laptop is flying along. Thanks again. Ron’s Son.

Hello,
would you mind sharing which update in particular if you remember? Same CPU, same situation for quite a while and I'm quite desperate

Finally solved (thanks Claude). I'm sharing what I did for anybody's future reference on my i7-1195G7.

I used ThrottleStop to inspect the power limits: no overheat indicator, just POWER being highlighted in red.

Opening the detail TPL form PL1 was set to 10 Watts with no way to change it (No wonder I could only get 0.80GHz out of this with such a low power limit).
I tried booting a Linux live USB to see whether the same limit was editable from there or not

S=/sys/class/powercap/intel-rapl-mmio/intel-rapl-mmio:0 sudo sh -c "echo 28000000 > $S/constraint_0_power_limit_uw" cat $S/constraint_0_power_limit_uw

Since the final line would print 10000000 instead, it meant even from Linux it wouldn't be possible to set a higher power limit.

It probably meant that the powercap was set and locked from the hardware.

The final solution was to force the BIOS reflash:

1. Shutdown the PC

2. Press Win+B, then also the power button, holding them all for at least 3 seconds.

3. After quite a long black screen, it shows the BIOS reflash procedure, let it finish and follow the instructions if any.

4. Let it reboot

I'm finally getting 4GHz peaks again.
