Changed batteries then light blinks then goes off...

If you are unable to change the IP address of your Zebra LP 2844-Z using the ^default command or Zebra Utilities, and updating the BIOS did not help either, you may need to try a factory reset of the printer.
To do this, follow these steps:

1. Turn off the printer.
2. Press and hold the feed button on the front of the printer.
3. While holding the feed button, turn on the printer.
4. Wait for the status light to turn solid red, and then release the feed button.
5. The status light will blink green a few times, and then turn solid green.
6. Press and release the feed button once. The status light will blink red a few times, and then turn solid amber.
7. Press and release the feed button again. The status light will blink green a few times, and then turn solid green.

The printer should now be reset to its factory settings, including the default IP address of 192.168.168.168. You should now be able to access the printer through this IP address and change the settings as needed.

If it's blinking green it means it's on mute. Unmute it and you should have solid green. It doesn't turn red.

Sounds like a bad lamp to me

I’m happy to assist further over the phone at https://www.6ya.com/expert/robert_54ae41aaaffbab00

sounds like the battery is bad if theres power up but turns of when unplugged then bad batt

sorry

You may have a DC Jack issue and needs to be replaced. Common with Acer models using the yellow DC jacks.

And since the battery will not charge, it is most likely a component issue. Shorted MOSFET in the charge section.

sound to me like you have a bad battery, a lot of ryobi batterys don't last like they should i have had the same problem, but my battery was less than a year old and i took it back and they give me a new one.

Try a new or other charger, problem may be with the charger.

you need to hold the power slide jup for a couple of seconds then the light should stay solid, or your battery might not be fully charged.

Ensure That your Power button is clicking back and staying connected - this would cause the computer to shut down immediately.
