I am a HP user since 2013, I bought new computer of hp with set of monitor, CPU, keyboard, mouse and ups
almost its going well . But one thing that I observe is very annoying that is its ups. It is HP UPS 800 VA, whenever
power supply goes off the electricity from UPS keep my PC turn on for 12 min to 17 min only whether company says it will give supply to 25 min to 30 min . Later its battery gone dead in 2 years. My many important documents were not save which I work for many minutes.
