Troubleshooting the notebook battery
This document pertains to HP Notebook PCs.
If your notebook computer battery does not power the notebook or will not hold a charge, troubleshoot the battery to see if it needs to be replaced. If the battery indicator LED, located near the power icon, either does not glow or always blinks, there is a battery problem. Your computer might operate correctly when it is connected to the power adapter, but not when using battery power.
NOTE:The maximum capacity of the battery decreases over time and with use. Loss of battery capacity varies depending on the product configuration and usage, including but not limited to: product model, applications running, power management settings, and product features. The battery warranty does not cover natural deterioration of battery capacity. Your battery is warranted from defects in materials or workmanship resulting in failure. When contacting HP Service and Support, you might be required to run an HP diagnostic test to determine if your battery is covered under the warranty.
Troubleshooting the notebook power supply
Before troubleshooting the notebook battery, make sure the power supply is functioning properly. To check the AC adapter and power source, follow these steps:
- Plug one end of the AC adapter cable directly into a functioning wall outlet, and then plug the other end into the computer.NOTE:Do not plug the AC adapter cable into a power strip, surge protector, or secondary power source.
- Make sure the notebook is receiving power from the power source. Check the following:
- Unplug the AC power cable from the notebook, then remove the notebook battery. Plug the AC power cable back into the notebook, then turn it on. If the notebook powers on, the problem is with the battery. Go to Troubleshooting the notebook battery .If the notebook does not power on, continue with the next step.
- Verify that all power cord connections are secure. Check the AC adapter brick and make sure that any removable cords are secure.If the AC adapter connection to the computer is loose, the connector might be damaged and require repair. Contact HP service and support for further assistance (see Contact HP ).
- Verify that the power button or power LED is lit when the computer is on.Depending on the model, the battery indicator LED (also called the power LED) might be white, green, or amber when the power adapter is connected and is providing power to the computer. If the power LED is off, then continue on to the next step to check the AC power adapter.
- If the AC adapter brick features an LED power indicator, check to see if the LED is lit to verify that the computer is receiving power from the wall outlet. If the LED does not turn on, try plugging the AC adapter into a different outlet to check the power source. If the LED still is not lit, you might need to replace the AC power adapter.
- Feel along the length of the AC power cable and check for any kinks or breaks. Check the ends for any broken connections. Inspect the AC adapter brick. If it is discolored or warped, or if there are any problems with the power cord or connections, replace the AC adapter.
- Verify that the AC power adapter is the correct type.The computer was shipped with the correct power adapter, however, if you have multiple adapters, make sure that you are using the correct one for your computer.Older adapters were rated at 60 watts, but newer notebooks require adapters with 90 or 130 watts.
If you need to purchase a replacement AC power supply, make sure you use the model number of the computer and check for the correct part number for the adapter at the HP Parts Store . You will also need the model number if you call HP Customer Service. See Locating the Product Number and Support Information for the Notebook PC .
