One of the advantages of laptops is that they are easy to carry and can work for hours on their own batteries anytime, anywhere. However, we often encounter some strange problems,such as the HP laptop battery drains to 0% after shutdown, which has a great impact on your work. The following is a description of the solution to the power drain fast of HP notebook after shutdown.
Part 1: Why Does My HP Laptop Battery Drain When Off
After the notebook is turned off, the battery power loss is fast, and it may drop by a few percent or ten percent when it is only placed for several hours, which is much higher than the expected. In fact, mainly for the following two reasons:
1. The "Wake on LAN"
It is enabled on in the notebook; this feature will allow the computer to remain active even if it is turned off. You can disable Wake-on-LAN test in Device Manager-> Network Card Properties-> Advanced-> shutdown Wake-On-Lan
2. A laptop with a USB Charging Port is still in use after shutdown.
For these two reasons, I have summarized two solutions, I hope to help you for hp pavilion battery drain when turned off:
1. Turn off Wake on LAN
1.1 Open "Device Manager" - "Network Adapter", right click on the item of the network adapter to be set, select "properties"
1.2 Select the "power management"- "allow computer to turn off this device to save power" and uncheck it;
1.3 Select "Advanced" to disable the "Wake-up" option.
Note: If this option is checked, any activity on the network will consume the battery without the power adapter.
2. Disconnect the USB device
Many models of notebooks will allow the USB interface to charge the mobile device when it is turned off or in sleep. USB interface with this feature will print a lightning sign next to the port. Enter BIOS, find Always USB or WAKE ON USB, turn off this option.
To avoid hp laptop consume power even after shut it down, please disconnect the device on the USB port with charging function (including USB mouse, keyboard, mobile disk, mobile phone, etc.) after the laptop is turned off.

Second, go to the config-USB- "Always on USB" option, set it to Disabled, F10 to save the settings, and exit the reboot. This is to turn off the USB power supply so that it does not power the USB device when it is turned off.
4. Disable fast startup
Sometimes hp battery drain after shutdown may be caused by the quick startup. This feature combines the shutdown and hibernation features to get your PC up and start fast. But it can cause battery drain even when the PC is turned off.
