3-8 Troubleshooting and Diagnostics HP Omnibook XE3 (Technology Code GF) Symptom Call Center: Suggestions Repair Center: Likely Causes Repair Center: Comments Notebook has short operating time. Turn down display brightness. Check timeout settings in Power Management or Power Options in Control Panel. Restart computer, press F6 when HP logo appears, and follow onscreen instructions. This calibrates the battery, and requires four to five hours. You cannot use computer during this process. Certain applications can cause excess CPU and power usage. (User can get Intel Power Monitor from www.intel.com and monitor CPU load.) W hen playing DVD movies on battery power, make sure processor runs at optimum speed for movies: use Power Options or Power Management in Control Panel to select Portable/Laptop power scheme. W hen using applications with automatic save feature (such as MS W ord), extend save time or disable to reduce hard disk access and power usage. PCMCIA card use can affect battery life. Some PCMCIA cards draw power even while not in use. Heavy modem use can affect battery operating time. Battery. Motherboard. Battery capacity often decreases after a year or more. Battery indicator is inaccurate. Time Remaining is an estimate based on how much power the notebook is using at that moment. It therefore depends on the current task, and assumes power will be used at the same rate until the battery runs out. So, for example, if the notebook is performing a task requiring a good deal of power (such as reading from a CD or DVD), the value will probably show too little time remaining.
