1.4 Batteries 1 Hardware Overview
Any of the following can stop the battery from charging:
1. The battery becomes fully charged.
2. The AC adapter or battery pack is removed.
3. The battery or AC adapter voltage is abnormal.
Detection of full charge
A full charge is detected only when the battery is being charged by quick or normal charge.
A full charge is detected when either of the following conditions are met:
1. The current in the battery charging circuit drops below the predetermined value.
2. The charging time exceeds the fixed limit.
NOTE: The time required for normal charge depends on the power consumption by the
system. Using a fluorescent lamp and frequently accessing the disk consumes more power and
lengthens the charge time.

2.2 Troubleshooting Flowchart
If you know the location of the malfunction, turn directly to the appropriate section of this
chapter. If the problem is unspecified, use the flowchart in Figure 2-1 as a guide for
determining which troubleshooting procedures to execute. Before performing any
troubleshooting procedures, verify the following:
Ask the user if a password is registered, if it is, ask him or her to enter the password.
Verify with the customer that Windows 11 is installed on the hard disk (SSD). Operating
systems that were not pre-installed by Dynabook can cause the computer to malfunction.
Make sure all optional equipment is removed from the computer
