Here is an update on things: Disabling the "Microsoft ACPI-Compliant Control Method Battery" does indeed allow me to run the laptop below 7%, however, this method is not a practical workaround because doing so also prevents other useful power management features. I have an email response from...

Well, it's Tuesday and no surprise I did not get the promised callback from HP support. So I took the initiative to call them to follow up. Was told that they will now escalate the matter to the highest priority and I will get a callback in 1 hour. I've waited more than an hour and no word...

This is really interesting reading. Particularly the bit where it says it must be set to a value between 0 and 5 to be ACPI compliant. Really keen to hear what HP has to say when (and if) they call back. I checked the battery driver that is installed on my laptop. It's ironic that it's...

Yeah, looks like I will give this a go if I can't find an alternative solution soon. In the meantime, calling all Windows 8.1 users who just happen to be reading this post but may not have a solution - could you please have a look at your Power Options and see if you can change the Critical...

I do not follow how AHCI drivers affect the battery settings. I thought AHCI drivers were to do with how data is exchanged between system memory and attached storage devices?

Exactly, and this is beside the point. What is more relevant is do you know how to fix the issue at hand? All you have suggested to me so far is that it is unwise to run the battery completely flat (which I acknowledged already) and that the setting is coded into Windows to not allow anything...

Thanks for the suggestions adamf. The key numbers correspond exactly with the ones in Windows 8.1 on my machine. It appears that changing the registry entries is the same as using powercfg from the command prompt. I edited the appropriate registry keys and it seems that the change is purely...

That's rather confusing. I mean no disrespect but I thought this was a Windows forum to discuss general support issues relating to Windows. As I mentioned before, I just want to set the critical battery level to something more reasonable than 7%. I think that should be achievable since adamf...

What I mean is having a look at your Power Options and see if you can even change it down to something as low as 1%, just to see if your Windows has a limit as well or not. I don't think doing this will kill your battery at all and hence waste any money by doing it. Thanks for the...

Here's an update: so I ran the laptop after disabling the Power service using msconfig - I got a low battery notification at 10%, then another notification at the Reserve Battery level of 5%. I ran it until 1% and it didn't hibernate. Plugged the laptop back to AC power before it reached...

I have just purchased a new HP Spectre x360 Convertible 13 laptop last week with Windows 8.1 installed as the operating system. It is the first time I have owned anything with Windows 8.1. Anyway, I am wanting to adjust the Critical Battery Level in Power Options to something lower than the...
