Lenovo Ideapad Z400 Touch Won't Turn On After Attempted Battery Firmware Update

Hello Lenovo Community!

I own an Ideappad Z400 Touch and I had issues with trying to charge it. Obviously I turned to the forums here and I found a possible solution here. When I tried to perform a battery firmware update, it went smoothly and then suddenly turned off and had a fast flashing orange light. Obviously I knew my battery and/or charger let me down in the middle of the process. I'm kind of scared because I don't know what to do nor have the money to afford a new laptop. What most likely happened to the battery is that it got "electronically disconnected" and technically only relies on the AC adapter which now I have found out is pretty screwed up and stops charging once Windows actually boots up. Is there any way to fix this? Please help!

 

Thank you and have a wonderful evening!

Hello Maf3

Thanks for using the Lenovo forums.


I would recommend you try a new charger if you are able to.

 

Try a static discharge for this, it may help to resolve the issue or at least get rid of any built up static on the motherboard.

(If the battery is internal, please just skip the remove/replace battery steps.)
1. Turn the unit off
2. Remove the battery and the Mains adapter
3. Press and hold the front power button for 30 seconds
4. Replace the battery and the Mains adapter
5. Turn the unit on as normal

 

You can also try and use the NOVO button to see if that is able to get you started up.

 

 If these steps do not work I would recommend, that you call your local Lenovo support line for a possible service. Below is the link to the phone list where you can find these numbers

 

Hope this helps, let us know how you get on.
