Archive for a motherboard coded Y61-MB-E, a 229 KB rar whose size and twin boardview entry suggest it holds board layout data for that revision E. No laptop brand or model is stated in the name. Boardview material for a specific revision helps locate components, pins and test points when tracing power rails or a shorted capacitor. Open it in a boardview tool such as OpenBoardView or FlexBV, and make sure the board marking on the PCB reads Y61 with revision E before relying on positions.
