Dell power schematic for the D400, judging by the name, packed as a 401 KB RAR archive. It appears to cover the power section rather than the full board. Typically that means the DC input, the battery charger and the system voltage regulators, but the file should be checked to confirm. No board number or revision is stated, so match the motherboard markings first. It is useful for tracing power rails, checking regulator enable signals and finding shorts on supply lines.
