HP Pavillion X360 with built in battery will not turn on

[LilacBreeze]

I noticed the mouse I use needed a new battery so I replaced it. when I came back the screen was dark on my laptop. I went to plug it in and nothing happened. There are no lights, no fan, completely blank and quiet. I tried to turn it on and held the button down for 15 seconds and still no changes. This is an HP Pavillion X360 that has the built in battery, so all the solutions stating to remove the battery will not work. What can I do to get it to start up again?

These newer laptops use the same kind of batteries as cell phones, and like current cell phones, they are also sealed shut so you can't replace the batteries.

All you can do at this point is see if you can run diagnostics to check out the battery. You do that by pressing the Esc key repeatedly and then, when the HP Startup Menu appears, select Diagnostics (usually F2) and let it run.

If it is NOT possible to run diagnostics, or if that does not work, then there is NOTHING more you can do by yourself -- and there is NOTHING we can do because we have no way of accessing your PC from here to run diagnostics or repair hardware.

You will need to have the PC physically examined in a service facility by folks that can run their own diagnostics to determine what is wrong with it.

--------------------
If your PC is still under the original one-year HP warranty, or if you have purchased an extended warranty from HP and this is still valid, then having HP do this is an inexpensive option for you. In that case, you should contact HP Customer Support to see about having it repaired or replaced under warranty.

To contact HP Support see the following link to create yourself a case number, then call and it may help speed up the call process:

Step 1. Here is the link: https://support.hp.com/us-en/contact-hp
Step 2. Enter Product number or select to auto detect
Step 3. Scroll down to "Still need help? Complete the form to select your contact options"
Step 4. Scroll down and click on: HP contact options - click on Get phone number

Case number and phone number appear.
--------------------
If your PC is no longer under warranty, then it will cost you up front to have HP examine your PC. If you want to do that, you will have to contact an HP Repair or Service Center to see if they can examine the PC to determine the cause(s) of the problems, if it can be repaired, and an estimate of the repair costs.

If you live in the U.S., here is a link to the HP Service Repair Centers:
