Notes

Power

(From forum.vcfed.org)

Power adapter is a Delta SMP-422CB, likely Rev B3, potentially Rev D0.

The laptop can be powered without a battery by running 5.5V and >= 3A to the three V0 pins (1, 2, 3), and ground to pin 8 and optionally the shell. The remaining pins seem to support the battery.

  1. V0 (+5.5V)
  2. V0 (+5.5V)
  3. V0 (+5.5V)
  4. SYS IN USE
  5. MH/CD
  6. BATT+ (+8.35V)
  7. BATT+ (+8.35V
  8. GND
