Troubleshooting the Counter
156 Assembly-Level Service Guide
Testing the battery
7 On the Battery assembly, push and hold the white test button on
the battery while observing the charge-level indicator. (See
Figure 2-13). The charge level should be at least 25% to be
functional. If the battery has been installed for over 24 hours with
counter AC power connected the entire time, the charge level
should be 75 to 100%. (Typically at least 25% after 1 hour charge.)
Figure 2-13. Test Button and Charge Indicator
8 With counter AC power still disconnected, use a DMM to measure
the DC voltage on the battery charging assembly 8-pin connector
(J100, still connected to the motherboard) from pins 5 & 6 to
ground.
• Both pins should read between +10 and +13 VDC.
9 Connect the AC power cord to the counter.
• The Power LED next to the counter Power switch should be off
(Standby mode).
10 Repeat step 8.
