Acer 12 R851TN Chromebook Daughterboard 55.H99N7.001

Restore serviceability in supported Acer 12 R851TN Chromebooks with a genuine replacement daughterboard. This OEM component is intended for board-level repair when internal hardware has failed, giving IT teams and repair technicians a direct path to bring a device back online without replacing the entire system. That approach matters in environments where uptime, repair cost, and asset retention all affect the bottom line. A targeted daughterboard replacement can shorten depot cycles, simplify parts planning, and keep more devices in circulation across education, shared-workspace, and enterprise deployment models. Because this is an Acer-sourced part, it is aligned to the original platform requirements of the R851TN family. That helps reduce guesswork during service and supports consistent repair outcomes across a mixed inventory. When the goal is to preserve device value and return users to work quickly, exact-match components are the right choice.
