Try the following and see if it will turn on...

1. Unplug your charger cord.
2. Remove the battery.
3. Press and hold the "Power" button for 30 seconds.
4. Now plug back in the power/charger cord.
5. Now put the battery back in.

If this doesn't help, then test the power cord to see if it is good. Either try your cord in another device, or try another devices cord in your laptop. You may also want to try charging it when the device is off, rather than on. If it works then, the cord is probably the issue.

Should that not be the problem, then check the battery to see if it needs replacing.

You can not take the battery of ProBook 450 G4 out unless you really know what you are doing.
Non-technical person can never do that.

There are many videos out there that can help walk one through it. If you feel comfortable trying to do it yourself. Not everyone does. Also, if it is under warranty then the manufacture should be contacted.
