HP Spectre - power button does not work when docked or closed

HP Spectre x360 13-ac0XX
I bought a Philips monitor with USB-C which works well. HOWEVER the power button on the Spectre does not work at all when the lid is closed. I cannot power it on or power on from a hibernate state.
I really would like to use this monitor with a keyboard and have the option of th elaptop either flat on the desk or in a vertical slot -type stand. Opening the laptop every time to turn it on seems perverse.
I have disabled te lid close action in the power profile menu - so to be clear I am talking about initial power on and waking from sleep and hibernate.
Ideas please.

 

afaik, it's deliberate to prevent accidental power on. I remember having a side power "button" (it really was a slider toggle) on my old Vaio that could work when the laptop screen was closed, and there was an option in the BIOS to enable this behavior.

Can you wake it from sleep?
Specifically, if your KB has a power button, does it work with the laptop? (I know very little about consumer HP BIOSes, but wake-on-usb is usually present on their enterprise/business laptops). However, wake-on-usb only works with standby/sleep, and not a complete power off.

 

Jeremy, thankyou. I will try to wake from sleep mode, but do not have much hope.
I have several keyboards, the one at the moment is a Dell wired USB keyboard. No power on button.
I do have a Logitech wireless media keyboard, with one of their universal dongles. Not sure if this has a power on function.

It looks like you have to make settings to enabe USB power on though. In the HID drivers I have a whole slew of devices named, but cannot check Power On under the Power optiosn for any of them.
Also in the Power Profuile settings I have enabled the USB Selective Suspend setting.

I am a bit pissed off - on Amazon there are loads of elegant stands which hold a MacBook or an ultrabook laptop upright and closed. I wanted to have the option of doing this.
Why do Apple allow it and HP do not?

 

I believe macbooks can be set to power on by plugging in the power cable. I just checked an old HP Proook 640 G1, and there is an option to power on upon plugging in power (again, in the BIOS/UEFI). Does your laptop have similar functionality?

 

• eremy, thankyou. But no option like that in the BIOS. I shall double check.
• I install and manage HPC equipment for a living - and BIOS settings are ctitical in that world. Normally set to stay OFF when power applied, to stop a whole rack of servers powering on at once and causing a surge.

 

I guess we could always go for the least intelligent method: leave the laptop in the "tablet" mode at all times. This should keep the power button enabled, at the cost of the screen and KB being constantly exposed.
