'''IBM Mobile Systems — ThinkPad Computer Hardware Maintenance Manual''', '''January 2003''', part number '''92P1840''', '''First Edition'''. 168 pages. It supports the '''ThinkPad T30 (MT 2366/2367)''' and the '''ThinkPad Dock (MT 2631)'''.
The '''IBM Mobile Systems ThinkPad Computer Hardware Maintenance Manual''' of January 2003 is IBM's service manual for the ThinkPad T30, part number 92P1840, First Edition (January 2003), 168 pages. The title page lists the ThinkPad T30 (MT 2366/2367) and the ThinkPad Dock (MT 2631). [[IBM ThinkPad T30 Hardware Maintenance Manual]] holds the Second Edition (February 2003), with the same part number, page count and contents list; it corrects typing errors in this edition and revises the keyboard part-number tables (p. 153), so check both when matching a keyboard FRU already fitted to a machine.


'''This is the first edition; [[IBM ThinkPad T30 Hardware Maintenance Manual]] is the second''', published a month later under the same part number. The two files are not identical. Where they differ, prefer the February 2003 second edition; this page is worth keeping because a first edition sometimes documents a FRU number that was later superseded, which matters when identifying a part already fitted to a machine.
== Contents ==


== What it contains ==
Page numbers are the manual's own.


IBM's ThinkPad hardware maintenance manuals all follow the same plan, and knowing it saves hunting:
* Introduction (pp. 3-21): strategy for replacing FRUs, error messages, diskette compatibility matrix, multilingual safety notices, safety information and the laser compliance statement.
* General descriptions (pp. 25-40): read this first, related service information including restoring the preloaded system, passwords (p. 29) and power management (p. 31); checkout guide (p. 35) with PC-Doctor and the power system checkout (p. 38).
* ThinkPad T30, from p. 41: product overview and specifications (p. 43), status indicators, FRU tests, Fn key combinations; symptom-to-FRU index (p. 50).
* FRU replacement notices (p. 57): screw notices and retaining serial numbers.
* Removing and replacing a FRU (pp. 60-131): numbered procedures from 1010 Battery pack (p. 61) to 3020 ThinkPad Dock top cover (p. 127).
* Locations (p. 132) and parts list (p. 136), with the T30 model matrix, LCD FRUs (p. 149), keyboards (p. 153), recovery CDs and AC adapters.
* Notices (p. 162).


* '''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.
== What this manual does not contain ==
* '''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 ==
The manual works at FRU level. It has no schematics and no component values, and a system board is a single part number. The only capacitor it mentions is the "bulging capacitor" hazard in the safety inspection guide.


'''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.
== What it settles ==


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.
The power system checkout (pp. 38-40) gives these limits: AC adapter output +15.5 to +17.0 V dc at pin 1; battery pack +0 to +12.6 V dc between terminals 1 and 5, discharged if below +11.0 V dc, and 4 to 30 kΩ between terminals 4 and 5 if above it; backup battery +2.5 to +3.2 V dc on the red wire.
 
Recharging a pack that reads under +11.0 V dc takes at least three hours, even if the indicator does not light (p. 40).
