Repairs we carry out on the Packard Bell oneTwo All-in-One M3870
Screen replacement
The 21.5-inch panel is the front of the whole machine. We replace cracked, dark or lined panels and check the backlight circuit, because a black screen on an all-in-one is not always the panel.

The 2.5-inch drive can be replaced with an SSD. Memory is in slots on most configurations and can be increased.
