System issues
I forgot my BIOS password and can’t access my tablet
• You can enter several incorrect passwords before the BIOS temporarily locks the system.
You can try again by restarting the system. If you still can’t log on, contact your system
administrator.
The tablet seems to be operating slower than usual
• Reboot.
• The hard drive or solid state drive (SSD) may be full or nearly full. You can use Disk
Cleanup to free up space on your drive. For instructions, open Windows Help and search
for “disk cleanup.”
• The hard disk drive may need to be defragmented. You can use the Disk Defragmenter to
consolidate files and folders on the hard drive. For more information, open Windows
Help and Support and search for “disk defragmenter.”
Note: Unlike traditional hard drives, SSD drives, like the one available on the CL920, see
no performance benefit from traditional HDD defragmentation tools. Using these tools
simply adds unnecessary wear to the SSD. It is recommended that you disable any
automatic or scheduled defragmentation utilities on your tablet.

“improve performance.”
Frequently asked questions
How can I make the battery charge last longer?
• By default, the power plan for the CL920 is a balance between optimal performance and
a long battery charge. If you want the tablet to run longer between charges, use the
Power saver power plan. Open Motion Dashboard, tap Power. Tap Power Options and
select Power saver.
• Use the Dynamic display setting. This automatically controls the display to conserve
power. Open Motion Dashboard, tap Display then tap Dynamic.
• Set the display to the dimmest level you are comfortable with. Open Motion Dashboard,
tap Display then move the Brightness slider to the desired level.
• Disable any unused devices. Open Motion Dashboard, tap Wireless and clear the
checkbox next to the adapters you aren’t using.
• Stop unnecessary background applications and processes.
How do I know if the tablet is charging when I plug it in to a power adapter?
• The battery gauge button on the left side of the tablet is amber when the tablet is
charging.
