Powering up and upgrading a Spectre X2 Ultrabook

[gewoon_mens]

I have a hand-me-down HP Spectre X2 Ultrabook (detachable). It came without a power supply/adapter. I would like to know: a) where can I buy a power supply (in Norway); and b) can it be upgraded to more current specs?

The label says "Windows 8," "Intel Core i5" processor; can it be upgraded to Windows 10, and made really useable?

On the bottom there should be a label with a model number or product number. With that, we can better assist. We can almost surely find you a power supply but upgrades on a tablet may be very limited. Unlikely the processor is upgradeable and even memory may be soldered on. You can likely install a solid state drive which is a serious upgrade, if it does not already have one.

Thanks for the reply. However, there is no such label on the bottom - only a "Pro Windows 8" sticker, and the "beatsaudio" branding. So, I can't figure out which power supply complements this model.

Once I do get it powered up, I can - hopefully - find out what elements are on-board. Do you mean to say that a tablet's OS cannot be upgraded to Windows 10? (I realize that Windows 8 is completely obsolete and unsupported.)

I did not say that I was speaking of hardware. Likely you can upgrade to Windows 10. Maybe a picture of it will give is some idea what it is?
