System Will Not Resume Operation; Display Screen Is Blank Or Difficult To Read; Infrared Data Transfer Is Not Working - Fujitsu Stylistic LT 800P User Manual

Troubleshooting Your Stylistic LT800P
Solutions to some common problems are described in the following sections. If you
are experiencing a problem with your tablet that you cannot solve by taking the
actions described, contact your local help desk or your reseller for further assistance.

System Will Not Resume Operation

If the system will not resume operation after system operation has been suspended,
check the following possible causes:
• The battery pack may either be defective, or discharged to the critically low level.
When the battery pack reaches the critically low level, the system is forced into
Suspend-to-RAM mode to avoid a total system power failure. To correct this
problem, either connect an external power supply (such as the AC adapter), or
install a charged battery pack in the tablet.
• The system may be at the critical thermal limit. To avoid damage to heat-
sensitive components, the system enters Suspend-to-RAM mode when it gets
too hot. System operation cannot be resumed until the tablet cools off to a
tolerable temperature. Move the tablet to a cooler location.

Display Screen Is Blank or Difficult to Read

If the display screen on your Stylistic LT800P tablet appears blank or is unreadable,
confirm that the system is running (the Power icon is displayed continuously on the
Status display), and check the following:
• The system brightness may be set too low, causing the screen to appear too dark.
Use the brightness hotpad to adjust the screen brightness.
• An external monitor may be selected. Tap on the Display Select hotpad to
determine whether the tablet display screen is selected.
• The video timeout may have expired. Tap on the display screen to reactivate the
display. Note that this is a normal, power-saving feature.

Infrared Data Transfer Is Not Working

If you are experiencing problems transferring data over the system's infrared
interface, note the following:
• Can the IrDA port on the tablet "see" the IrDA port on the other device? A
direct line-of-sight path must exist between the IrDA port on the tablet and the
IrDA port on the other device.
