Power, Start, and Battery Problems

n You may be running too many applications. Try to close

some applications or increase system memory for higher

performance.

Mode. These power saving options slow down the CPU to

conserve power. See Section 2

BIOS Setup

and Section 3

Battery Power / Power Management

for more information.

The notebook powers down as soon as it is powered on -

n Battery power may be extremely low. The circuitry prevents

a complete power drain, which is not intended for Lithium Ion

batteries. Use the adapter to charge it for several hours

before trying again.

The notebook beeps intermittently -

n When battery charge is critically low, an audible beep warns

you. Press Fn+F3 to turn off the warning beep.

The battery life gets shorter and shorter -

n The battery has a finite life of about 500 charge cycles. If

your battery is over one or two years old, it may be time to

have it replaced.

n Try a higher power saving setting in the BIOS or in the

Windows Power Management.

The battery does not charge -

n Make sure the AC adapter is plugged into a valid power

source.

n Check to see if the green lamp on the adapter is lit when it

is plugged in.

n The battery charge indicator LED on the notebook should be

lit when you plug in the AC adapter.

n Make sure the battery module is fully inserted in its bay;

make sure the battery latch is in locked position.

n If the battery is operating at a very high temperature, it may

not charge.
