Two ways to do it. I will show you the easier method first where you can power-up all the tokens you have.
Go to https://tribaldex.com/wallet, sign-up and click on the (stake) button shown in the image below and fill the blank space in the pop-up and click the "Stake" button.
Staking and powering-up means the same.
The second method is to sign-in to your https://www.hivelist.org/ page, go to wallet and then click on the downward arrow besides the liquid LIST amount. When you click the arrow it will display the dropdown you see in the picture below. Then click on "stake" to power-up your liquid LIST tokens. After that the liquid LIST will be transferred to LIST Power row. You can stake only your LIST token by this method.
