191 If Something Goes Wrong Resolving a hardware conflict If the AC power light still does not come on, check that the wall outlet is working properly by plugging in a lamp or other appliance. The AC adapter and power cable work correctly, but the battery will not charge. The battery doesn't charge while the computer is consuming full power. Try turning off the computer. The main battery may not be inserted correctly in the computer. Turn off the computer, remove and replace the battery. The battery may be too hot or too cold to charge properly. If you think this is the probable cause, let the battery reach room temperature and try again. If the battery has completely discharged, it will not begin charging immediately. Leave the AC adapter and power 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. The battery appears not to power the computer for as long as it usually does. If you frequently recharge a partially charged battery, it may not charge fully. Let the battery discharge completely, then try charging it again. Check the power options using the Toshiba Power Management Utility. Have you added a device, such as a PC Card or memory module, that takes its power from the battery? Is your software using the hard disk 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.
