ThinkPad Computer Hardware Maintenance Manual, September 2005, part number 39T5972, First Edition. 152 pages.
It supports the ThinkPad X40 Series, machine types 2369, 2370, 2371, 2372, 2382 and 2386. Unlike the X30 family manual it lists no dock.
A note on publisher. Lenovo acquired IBM's personal computer division on 1 May 2005. This manual's copyright line reads "© Copyright Lenovo ... Portions © Copyright International Business Machines Corporation", so it is a Lenovo publication for an IBM-branded machine. Cite it as such.
What it contains
IBM's ThinkPad hardware maintenance manuals all follow the same plan, and knowing it saves hunting:
- About this manual and Introduction — the strategy for replacing FRUs (reinstall the original part if the replacement does not fix the fault; if a machine has both a processor board and a system board, put the first one back before trying the second; remove multi-FRU assemblies one part at a time), how to use error messages, and the diskette compatibility matrix.
- Safety information — general and electrical safety, the safety inspection guide, ESD handling, grounding requirements and the laser compliance statement, with the safety notices repeated in every supported language.
- General descriptions and Related service information — restoring the preloaded system, passwords (including what can and cannot be cleared), and power management.
- Checkout guide — testing the computer, detecting system information with PC-Doctor, and the power system checkout: checking the AC adapter, operational charging, the main battery pack and the backup battery, each with its own measurement.
- Product overview — specifications, status indicators, FRU tests and the Fn key combinations.
- Symptom-to-FRU index — numeric error codes, error messages, beep symptoms, LCD-related symptoms, intermittent problems and undetermined problems.
- FRU replacement notices — the screw notices (torque and thread-lock rules, which matter on magnesium frames) and retaining serial numbers.
- Removing and replacing a FRU — the numbered 10xx sequence, which must be followed in order because later steps assume earlier ones.
- Locations — front, rear and bottom views by machine type.
- Parts list — FRU part numbers, including the keyboard and LCD part numbers by country and panel supplier.
What it does not contain
Module level, and firmly so. These manuals name FRU part numbers, not component values. Across a typical ThinkPad maintenance manual the word "capacitor" appears once, in the ESD handling note. There is no schematic, no board layout, no parts list below FRU level and no component data of any kind. A system board is one line item with one part number.
That is IBM's service model, not a gap in the scan, and it is why no ThinkPad on this wiki has a component-level capacitor list. If you need a board-level repair on a ThinkPad, this manual will tell you which board and how to get it out; it will not tell you what is on it.
