The IBM Mobile Systems ThinkPad 380XD (2635), ThinkPad 385XD (2635) Hardware Maintenance Manual is IBM's service manual for those two machines, form number S10L-9623-00, part number 10L9623, First Edition (May 1998), 132 pages. The earlier 380, 380D, 385 and 385D are in Volume 3 and Volume 4.
The product overview (pp. 22-23) lists the processor by model: the 380XD with a Pentium MMX at 233 MHz (2635-8xx, 9xx, Bxx) or 266 MHz (Axx), or a Pentium II at 233 MHz (Exx) or 266 MHz (Fxx); the 385XD with a Pentium MMX at 233 MHz (8xx) or 266 MHz (9xx), or a Pentium II at 266 MHz (Dxx). Standard memory is 32 MB on the system board, expandable to 96 MB.
Contents
[edit | edit source]Page numbers are the manual's own.
- Introduction (pp. 3-17): error messages, multilingual safety notices (p. 5), safety information (p. 12), laser compliance statement (p. 17).
- Read this first (p. 19) and product overview (pp. 22-23).
- Checkout guide (p. 25): audio, diskette drive, fan, keyboard, memory, power systems (p. 29), status indicators, system board and CPU card, TrackPoint III; optional device checkout (p. 33); power management features (p. 35).
- Symptom-to-FRU index (p. 38): numeric error codes, beep symptoms, and function, indicator, infrared, keyboard, LCD, peripheral and power symptoms.
- Running the diagnostics (p. 49), including the diagnostic error codes (p. 52); related service procedures (p. 55): status indicators, password combinations (p. 56), low-level format, maintenance diskette download, Fn key combinations.
- FRU removals and replacements (pp. 58-103): numbered procedures from 1010 DIMM card and backup battery (p. 62) to 2050 LCD cable (p. 103).
- Locations (p. 104) and parts listing (p. 107): system unit, drives, LCD FRUs (p. 111) and option parts (p. 118). Notices (p. 123).
What this manual does not contain
[edit | edit source]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.
What it settles
[edit | edit source]The power systems checkout (pp. 29-31) gives these limits: AC adapter output +15.5 to +17.0 V dc at pin 1; battery +0 to +13.5 V dc between terminals 1 and 4, discharged if below +11.0 V dc, and 4 to 30 kΩ between terminals 3 and 4 if above it; backup battery +2.5 to +3.7 V dc on the red wire.
