All-in-one PC reviews: Reliability

Using AIO PC

An all-in-one PC can be an ideal hub for all of your home computing. But with the brains of the computer living within the screen itself, if something goes wrong with the screen or the PC, you're left stuck. That's why it's important to choose an all-in-one PC from a brand you can trust. 

Every year we survey thousands of Which? members about their computing products to find out which are the most - and least - reliable. Our unique survey helps us to identify the brands that people trust, and would recommend to a friend, with verdicts on all-in-one PC brands like Apple, HP, Sony and Dell.

Customer score is based on satisfaction and the likelihood of recommending the brand to a friend.

Common all-in-one PC problems

Thanks to our unique survey, we're able to identify the most common problems when things do go wrong with an all-in one PC. Of all of the issues experienced by all-in-one PC owners, the most common specific problems are:

  • Screen freezing 10% - all-in-one PCs often boast large screens, but that's little use if they keep freezing.
  • Hard disk failure 10% - people reported problems with the PC's hard disk failing to read or stopped working completely.
  • It stopped working and I do not know why 8% - a PC can be a complex system and sometimes the troubleshooting is best left to a professional repairer.

Our reliability surveys help Which? to uncover common all-in-one PC problems that can affect owners over time. Combined with our extensive lab tests, this means we can recommend the best all-in-one PC for you to buy. We test all-in-one PCs to see how fast they are to start up and use, how comfortable the keyboard is in day-to-day use, and how sharp, bright and easy-to-view the screen is.

Which? is independent - we work for you, the consumer, so you can be sure that our product recommendations are influenced only by our test results. We don't take advertising and we buy all the products that we test, so our advice helps you to make the right choice and avoid costly mistakes.
