If the battery has completely discharged, it will not begin charging 
immediately. Leave the AC adaptor and power cord/cable 
connected, wait 20 minutes and see if the battery is charging.

If the battery light is glowing after 20 minutes, let the computer 
continue charging the battery for at least another 20 minutes before 
you turn on the computer.

If the battery light does not glow after 20 minutes, the battery may 
have reached the end of its useful life. Try replacing it.

If you frequently repeat shallow charge and discharge, the battery 
meter may become inaccurate. Let the battery discharge 
completely, then try charging it again.

Check the power options via your Power Plans (see 

). Have you added a device, such as a memory module, 

that takes its power from the battery? Is your software using the 
internal storage drive more? Is the display power set to turn off 
automatically? Was the battery fully charged to begin with? All 
these conditions affect how long the charge lasts.

After a period of time, the battery will lose its ability to perform at 
maximum capacity and will need to be replaced. This is normal for 
all batteries. To purchase a new battery pack, see your accessories 
information included with your computer, or visit the Toshiba Web
