PDF schematic covering the IBM ThinkPad T41, approximately 1.09 MB. No board number or revision is mentioned in the name, so compare the sheet title blocks with the printing on your system board before using component values. The diagram is a practical reference for tracing the adapter input, battery charging and system power rails, checking clock and reset signals, and finding test points while diagnosing a board that does not power on. It opens in any PDF viewer, where searching for net names helps follow signals from sheet to sheet.
