What All-In-One PCs gain in space they lose in the user serviceability and repair department. I've never been incredibly fond of the All-In-One PC form factor of computers, mainly for the reasons outlined above; an onerous effort is necessary to effect most any repair or upgrade.
Such was the case when I was charged with the repair of this Asus ET2220I, which had become progressively cantankerous with each use. Of course, such problems probably wouldn't have surfaced if the machine hadn't been mistakenly dropped on the floor at least once. The only trouble was that the owners were under the impression that a malware infestation was to blame!
Upon initial attempts to power on this machine, I was greeted with a severely corrupted display and odd bouts of flickering, with the display remaining on, but showing a black screen. Fiddling around with various components at least allowed for the machine's power on self-test to reveal that an overvoltage USB device condition was present, causing its failure to remain powered on beyond fifteen seconds.
The problems which had seemingly handicapped this machine vanished, almost without a trace. After all hope was nearly lost, a few choice slaps to its exterior seemed to bring it back to life! Anomalous display flickering notwithstanding, the machine seemed to function normally with no surviving ill-effects of prior transgressions by it or its owners.
