The IBM PS/2 N45 SL Hardware Maintenance Reference is IBM's 77-page service pamphlet for the PS/2 Notebook N45 SL (type 2614), dated 15 May 1992, part number 42G0485, form number S42G-0485-00.
Like every model-specific PS/2 pamphlet, it states on its first page that it "is intended to be used with the IBM Personal System/2 Hardware Maintenance Reference manual (part number 15F2190, form number S15F-2190-00) and the IBM Personal System/2 Hardware Maintenance Service manual (part number 15F2200, form number S15F-2200-00)". Those two general binders are not hosted here.
What it contains
Model-specific service material for the N45 SL: product description and system board features, the checkout and undetermined-problem procedures, power and battery checks appropriate to a battery machine, the symptom-to-FRU index, the removals and replacements sequence, the location views and the parts catalogue with FRU numbers.
What it does not contain
Module level only. IBM serviced these machines by field-replaceable-unit exchange, and this pamphlet reflects that: it names FRU part numbers, not component values. There is no capacitor list, no resistor list, no semiconductor list and no schematic anywhere in it. The power supply, the planar and each drive are single line items in the parts catalogue. This is why no IBM machine checked in this wiki's verification drive has a published component-level capacitor list — it is not that the manuals were lost, it is that IBM never wrote one.
It is also not a standalone book. IBM issued it as a pamphlet to be filed in a binder alongside the general-purpose IBM Personal System/2 Hardware Maintenance Reference (part number 15F2190, form number S15F-2190-00) and Hardware Maintenance Service (part number 15F2200, form number S15F-2200-00), which carry the safety information, the general checkout procedure and the option and adapter sections. Those two general volumes are not hosted here.
No text layer — an image-only scan.
What it settles
The N45 SL is also covered, alongside the L40 SX, CL57, N51, P70/P75 and the early ThinkPads, by IBM Mobile Systems Hardware Maintenance Manual Volume 1. If you are working on an N45 SL, read both: the Volume 1 treatment is the later and fuller of the two.
