Power Supply Troubleshooting

The T2150 series power supply controls many functions and components in the T2150 series.
To determine if the power supply is functioning properly, start with Procedure 1 and continue
with the other Procedures as instructed. The procedures described in this section are:

Procedure 1:

AC IN LED Indicator Check

Procedure 2:

Battery LED Indicator Check

Procedure 3:

AC PS Unit Replacement Check

Procedure 1

AC IN LED Indicator Check

The T2150 series AC PS unit converts AC power to DC power and contains a charging
circuit which charges the T2150 series batteries. The AC power cord connects to the AC IN
socket connector on the back side of the computer. When the AC power cord is connected to
the T2150 series and the power is turned off, the AC charges the batteries.

The AC IN indicator displays whether or not the AC power cord is connected and supplying
power.

When the AC IN indicator is green, the AC power cord is connected and supplying power to
the T2150 series.

If the AC IN indicator does not light, the AC power cord is not supplying power to the T2150
series or the AC power cord is not attached to the T2150 series, go to Check 1.

If the AC IN indicator is flashing orange, the AC power cord’s voltage supply is abnormal or
the power supply is not functioning properly, go to Check 2.

If any of the above indicator conditions are abnormal, make sure the LED indicator lights are
not burned out before performing the following Checks:

Check 1

Make sure the correct AC power cord is firmly plugged into the AC IN socket on
the back of the computer.

Check 2

If the AC IN indicator flashes orange when the AC power cord is connected,
output voltage is abnormal. Connect a new AC power cord and turn the T2150
series on again to verify the indicator condition.

Check 3

The battery pack may be malfunctioning. Replace the battery pack with a new one
and turn the computer on again. If the problem still exists, go to Procedure 2.
