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. 36-39) gives the battery pack as +0 to +12.6 V dc (lithium-ion) or +0 to +13 V dc (NiMH) between terminals 1 and 6, discharged if below +11.0 V dc, and 4 to 30 kΩ between terminals 5 and 6 if the pack reads more than 9 V (lithium-ion) or 8 V (NiMH).
