2.2  Recharging the Battery

The Lithium-Ion battery is recharged internally using the AC adapter. To 
recharge the battery, make sure the battery is installed and the computer 
is connected to the AC adapter. 

There is no “memory effect” in Lithium-Ion batteries; therefore you do not 
need to discharge the battery completely before recharging. The charge 
times will be significantly longer if your notebook PC is in use while 
the battery is charging. If you want to charge the battery more quickly, 
put your computer into Suspend mode or turn it off while the adapter is 
charging the battery. 

Low Battery State 

When the battery charge is low, a notification message appears. If 
you do not respond to the low battery message, the battery continues 
to discharge until it is too low to operate. When this happens, your 
notebook PC goes into Suspend mode. There is no guarantee your data 
will be saved once the notebook reaches this point. 

CAUTION:To protect your notebook from damage, use only the 

power adapter that came with it because each power adapter 
has its own power output rating. 

Once your notebook PC goes into Suspend mode as a result of a dead 
battery, you will be unable to resume operation until you provide a 
source of power either from an adapter or a charged battery. Once you 
have provided power, you can press the Suspend/ Resume button to 
resume operation. In Suspend mode, your data is maintained for some 
time, but if a power source is not provided promptly, the Power indicator 
stops flashing and then goes out, in 
which case you have lost the data that was not saved. Once you 

provide power, you can continue to use your computer while an adapter 
charges the battery. 

Battery Replacement 

There is danger of explosion if an incorrect battery type is used for 
replacement. For computers equipped with a replaceable Lithium-ion 
battery pack, the following applies: 

● If the battery is placed in an OPERATOR ACCESS AREA, there shall 

be a marking close to the battery, or a statement in both the operating 
and the servicing instructions;  

● If the battery is placed elsewhere in the computer, there shall be 

a marking close to the battery or a statement in the servicing 
instructions.

The marking or statement shall include the following or similar text: 

CAUTION: Risk of explosion if battery is replaced with an 

incorrect type. Dispose of used batteries according to the 
instructions.

* If you happen to leave your battery pack to go through an extended period of 
self-discharge, say more than three months, the battery voltage level will become 
too low and needs to be Pre-Charged (to bring the battery voltage level high 
enough) before it automatically resumes its normal Fast Charge. Pre-Charge may 
take 30 minutes. Fast Charge usually takes 2~3 hours.
