So, looks like a great computer. Except they sent the wrong power adapter. And no specs to buy a replacement one…
Since it has an HP warranty, you might reach out to them to see if they’ll send you the correct one.
Hint: Register the computer first on their site. Makes things go faster.
If that doesn’t work, reach out to Woot! Customer Service.
From a browser, use the Woot! Customer Service form.
In the Woot! App, choose Account from the bottom navigation and then Support.
Note: Woot! Customer Service replies go to the email address on your Woot! account, not your Amazon login email if used/different.
