 If the size of the power adapter used is the following:

1, too small-the voltage provided is not enough to start the notebook computer, the battery led will Flash 8 times quickly, and in the lower right corner of the screen display a notification message "The output power of the HP Smart AC Adapter connected to your computer is insufficient. Please connect a higher capacity AC adapter. "

For example, if you try to use a power adapter designed for HP's mini computer on a laptop that is on a regular size, this error message may be displayed because the adapter does not provide enough voltage to start a regular-sized HP laptop. Please use the power adapter that came with your portable computer. If you need to use a replacement adapter, refer to HP laptop-order the HP certified replacement part.

2, good enough-the voltage provided is sufficient to start the laptop, but not enough to provide the required performance, a notification message appears in the lower-right corner of the screen "the HP Smart AC Adapter connected will power the computer, but at Reduc Ed performance. Please connect a higher capacity AC adapter to full performance.

For example, try using a 65W AC power adapter that is designed for high-performance laptops but has not been optimized for performance. However, a high-performance hp laptop requires a 90W AC power adapter. Use the power adapter that came with your laptop to achieve optimal performance. If you need to use a replacement adapter, refer to HP laptop-order the HP certified replacement part.

3, too large--the supply of voltage beyond the need to start a laptop, then HP's over power protection technology will prevent damage to your notebook computer.

For example, if you plug a 90W power adapter for a high-performance notebook computer into a portable computer that requires only a 65W power adapter, HP's over power protection technology will prevent damage to the notebook computer.

Workaround:

You can use the Microsoft Automated Diagnostics tool to automatically fix problems with your laptop's power usage and battery life.

Also, automatic detection of system settings that can affect battery usage, such as time-out and sleep settings, display settings, and screen savers, may need to be restored to their default settings.

• The time period before the computer goes to sleep is set too long

• Use a screen saver instead of setting your computer to go to sleep mode

• Display brightness setting is too high

• No power plan is set to the most efficient power plan

• Wireless adapter not optimized for energy saving

• Minimum processor State setting is too high

If you use a non-standard power adapter in your HP laptop, there is a battery performance problem that you can refer to in this article.
