Power Management Tips
❑
If you find that an application exhibits unexpected behavior (such as
reduced video quality) after returning from a reduced power
consumption mode, you should close that application before your
computer enters a power-saving mode.
❑
For maximum audio and video performance, use PowerPanel to
select either the AC Power Profile or the Power Management Off
profile.
❑
If your battery level falls to less than 10 percent, you should either
attach the AC adapter to recharge the battery or shut down your
computer and insert a fully charged battery.
If Your Computer Does Not Start
❑
Check that the computer is plugged into a power source and that it is
turned on. Check that the power indicator on the front panel of the
computer indicates that the power is on.
❑
Check that the battery is inserted properly and that it is charged.
❑
Make sure there is no diskette in the floppy disk drive.
❑
Confirm that the AC adapter and all cables are connected firmly, as
described in “Connecting Peripheral Devices” in the VAIO

❑
If you plugged the computer into a power strip or UPS, make sure the
power strip or UPS is turned on and working.
❑
If you are using an external display, check that it is plugged into a
power source and turned on. Check that the brightness control is
adjusted correctly. See the manual that came with your display for
details.
❑
Moisture condensation may have occurred. Do not use the computer
for at least one hour and then turn on the computer.
❑
When the internal backup battery is low on power, it may not be able
to boot your system properly. You can correct this situation as
follows: Plug in the AC adapter and allow the computer to charge for
one hour while the power is on. Do not use the computer during this
time. After one hour, turn the power off and then on again. To charge
the internal backup battery fully, keep the AC adapter connected for
more than 24 hours after turning the power on. You can use your
computer while charging the battery.
