LEP 9100 AC - Laptop Power Supply

Part of the hardware bundle for the 386SX−9100 was an AC adapter for charging the laptop's main battery as well as using the computer plugged in without having to rely on the battery as the only power source. The LEP−9100−AC power adapter was styled to blend in with the user's computing environment, sharing a similar style and color to that of its parent laptop computer. The end−user would have found utilizing the LEP−9100−AC very intuitive and easy to setup when a power outlet was readily available and could indefinitely extend their laptop computing session.

The LEP−9100−AC power supply unit offered a universal three−prong IEC C14 input connector, so any IEC C13 power cable could have been used if the user were to lose the original removable power cable. The power supply's input voltage ranged from 100 volts to up to 240 volts at 50Hz or 60Hz, which made this an international power supply useable in almost any global region. The power output had two modes: mode 1 included +12 volts, 2.2 amps main and 0.12 amps charge while mode 2 included +12 volts, 0 amps main and 1.0 amp charge, that indicated that while plugged in, the adapter trickle charged the battery while the computer was in operation, and gave a full charge current when the computer was not in operation.

Physically, the LEP−9100−AC power adapter was the exact same shade of beige as its 386SX−9100 notebook that it powered. This aided in allowing the power adapter to better blend in on the user's desk. The power unit's dimensions were 6" long, 2 7/8" wide that tapered to 2 ½" wide at the other end, and 1 ½" tall. The built−in cord that plugged into the laptop measured 6' and 3" and the outlet to AC adapter cord measured 6', allowing the user a great deal of freedom, over 12', when plugged into the wall. The top of the unit offered basic styling that blended well with the computer with perpendicular vents spanning 75% of the unit's' body. Within the perpendicular vent lines were the indicator LEDs. Both of these LEDs were green in color and the bottom LED was a steady−state light that indicated that the unit was receiving power. The top LED was a charge indicator and remained illuminated only when a charge was being provided.
