Rated 5 out of 5 by from Wow!! This was my first new desktop in 13 years. I’d never seen an All-In-One before. I was so “used” to all the cables and plugs and the hassle of a tower, monitor and speakers and all the space they took up. I absolutely LOVE this All-In-One! It’s lightening fast, easy to use and has great features. I’m a loyal HP customer and this is why. Highly recommended.

Rated 5 out of 5 by from Love our HP All-in-One We've owned an HP all-in-one for several years. It functioned very well and met our needs. So when it was time to update, we ordered another similar one from HP.

Rated 5 out of 5 by from Great product Very easy to connect to the internet responds well I love how the monitor and computer are in the same place no tower

Rated 5 out of 5 by from Not what I expected I thought I would be thrilled but so far it has been such a challenge what a difference between Windows 11 and Windows 10 I guess older people should not have a computer

Rated 4 out of 5 by from Excellent physical and functional machine Home user, single machine, 2 wks use: Quite happy with this AIO. Solid heavy base takes up little space. Screen not wobbly. Wired mouse and keyboard fine, and not too clicky, and easily replaced with personal upgrades (backlit, wireless, etc.). Sound with 4w speakers is quite good as far as volume and clarity, but adjustments minimal, for example no independent bass or treble adjustment. External speakers with their own adjustments do appear to work OK from the headphone jack. Quiet (no HDD). Quick actions with current config. Wish the ports were placed in a better location so that I did not have to arch over or turn around the monitor to its back to plug in......perhaps put all or some on the sides where much more reachable. USB hub helpful for this. Additionally the lettering on the AIO for ports is so small as to be unreadable without flashlight and magnifying glass. I would like each port labeled with is specific type and an "icon of the appropriate male plug" both which can be read upside down (if reaching over monitor to plug in). Repair-ability is an issue with this computer and worldwide. A repair-ability score, or attestation would be helpful, especially as AIO's do have a bad rep for this. Some computers now sold make an effort to make this clear and certified. HP apparently does not. Very much not a fan of Win 11 and wish unit had been sold with Win 10 with optional upgrade (wait a year or two until bugs and confusion, especially navigation, controls and setup, are worked out of Win11 and OneDrive, if ever.) HP does not seem to be of significant help with this though Win11 sold as an integral part. Both HP and Win11 have "improvements" available w/ and w/o a download, but the description of what those improvements will do is vague or absent and cannot be identified w/o spending a good time looking elsewhere before pushing "start", "reset", "install" etc. Surely HP can indicate (goes for Win 11 too) clearly what their additions will and will not do before loading and starting the "unknown" process. Overall, quite pleased, as unit physical features are clearly better than what I had before for the same relatively low price (considering inflation). On the other hand instructions for use

Rated 4 out of 5 by from Reaction Very good so far. One issue: goes to sleep sometimes, and won't start up: have to unplug and restart.

Does this product require an additional PC tower to be purchased with it in order to work?

Asked by: Claire23
Hello, Claire. Thanks for your question. No. An HP all in one computer has combined the monitor and computer tower into one with speakers, a microphone, and a webcam built-in. The only things you would need to do is plug in are the keyboard, mouse, and power cord.
