HP Spectre x360 i7-8705G running underclocked after returning from sleep

[SveinBerg]

I have the same issue with my HP Spectre x360 i7-8705G. It happens whenever the laptop awakes from sleep. The processor will have a max frequency of 0.7GHz until I take out and reinsert the power cable. It is not linked to any overheating, as it happens the moment the computer awakens. Is there any fix for this other than pulling out the power cable?

Welcome to our humble abode, the family and tech-friendly house of HP Forums!

I'll be your host for the day, they call me the Riddle_Decipher.

Have you attempted to upgrade/update the graphics card driver?

(Click here to find and install the latest drivers for the same, also include updates for BIOS and Ch...)

If the issue persists, try the below steps:

Press Windows + X > Select Power options > Click on Advanced settings on the right corner > Change (selected) plan settings > Change advanced power settings > look for the below options:

The Link State Power Management is a part of PCI Express Active State Power Management (ASPM). The link State of a PCIe Device is converted from L0 (on) to L1 (off) when the link is not transferring data.

The hardware is automatically converted to L0 again when data is available to transfer across the link. 

There are basically 2 levels of power management in the PCI Express options.

The difference between these 2 options are the power savings versus the Latency (Time to recover from the Sleep state).

• If you select Off, there are no power savings, and the current will run regardless of what state the laptop is in. (depending on if your laptop is plugged in or not).
  • On battery: Off = PCI Express will communicate even when using battery power.
  • Plugged in: Off = PCI Express will communicate when plugged in as well.

• If you select Moderate Power Savings, the power savings are less, but the time to recover from the Sleep state (latency) is much shorter.
• If you select Maximum Power Savings, the power savings are greater, but the time to recover from the Sleep state (latency) is much longer.

Sometimes this mechanism causes a bit of trouble during power transitions, especially during sleep. So it may be wanted to turn the Link State Power Management off.

Let me know how that pans out

I will have a colleague follow-up on this to ensure it's taken care off, in case you don't respond in the next 24-48hrs,

As I need to know if the issue has been resolved, to get proper sleep at night.

Hi @Riddle_Decipher,

Thank you for your reply. I have installed all the latest drivers and also the latest BIOS, but I saw that the Link State Power Management was set to maximum power savings for both plugged in and on battery. I set it to off for plugged in, so we'll see if this solves the problem. I will post an update after trying it for a while. I briefly put my laptop to sleep and awakened it right afterwards, and then it was not going into slow mode. So that is a positive sign!

Regards,

Svein
