'''Two corrections to this page's title.''' The file is '''byte-identical''' to the one on [[IBM ThinkPad R40 Hardware Maintenance Manual]] — same size, same SHA-1 — and '''the manual does not cover the R40e'''. Searching its 178 pages for "R40e" returns nothing; IBM's own scope statement is "IBM ThinkPad R40 product", and the machine types documented are '''2681, 2682, 2683, 2722, 2723 and 2724''', which are R40 types. | |||
The document is the '''ThinkPad R40 Hardware Maintenance Manual''', part number '''92P1332''', '''First Edition (February 2003)''', 178 pages. An R40e owner will not find their machine in it. This page is kept so that searches for the plainer title still reach the manual, but cite [[IBM ThinkPad R40 Hardware Maintenance Manual]]. | |||
== 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. | |||
