Is my all-in-one dead?

Has there been ANY damage? Have you tried another Cord/Charger with the EXACT same power specs? Has the AC jack been damaged due to pulling on the cord while plugged it? Unplug, remove battery, plug in, try to reboot. Has it been overheating? Fan, vents, heatsink clean?

Unplug, remove battery, plug in, reboot, select Normal Boot.

shut down laptop, unplug, remove battery, Reboot Moden/router , allow it to selftest, plug in laptop, reboot.

It may be the power supply in the set or another board--

What I would try (if have not done this) is unplug set any box or receiver etc for a while and then plug all back in one at a time to see if a reboot will clear this up.

Also look to see if same issue with nothing but a DVD player connected to the set.

If its in the set it will be most likely the main board (most expensive one).

Do the lights on your dash come on like they should?
IF SO, try starting the vehicle in neutral!

TRY HOOKING THE LAPTOP TO AN EXTERNAL MONITOR IF THE MMONITOR IS OK. THEN ITS THE CABLE CONNECTING THE KEYBOARD TO THE SCREEN. HOPE THIS HELPS. THS HAPPENED TO ME GOOD LUCK

A quick fix for most communication errors can be achieved by resetting the printer and/or rebooting the PC. Simply disconnect the printer from your computer. Reboot your pc. Unplug and re-plug the printer into the power source to reset it. When the printer turns on, reconnect it to your computer. Then try to print again once the computer fully recognizes the USB connection.

If that doesn't help, try the steps below:

1. Disconnect the printer from your computer.

2. Re-brick your printer. Pull out the power supply, black box where the power cord is plugged in at the back of the printer, and put it back after 30 seconds.

2. On your computer, go to Control Panel > Printers and Faxes.

3. Delete the Lexmark print object.

4. Reboot your pc.

5. When your pc turns on, reconnect the printer.

6. Wait until your pc fully recognizes the USB connection. To check, go to Control Panel > Printers and Faxes. If you see a new Lexmark print object in the list, then try to print a document again to verify that the problem is fixed.

This could be connection to webcam is loose or unplugged. Is this a USB webcam connection or onboard? If it is USB, check connection, unplug and plug it back to see if it works. Reboot your laptop might help. If still not workings, you might need to uninstall and reinstall it. Thanks

You should Open Devices and Printers. Then remove the printer. Then open Device Manager and remove the USB connection for the device. Use the "Show Hidden devices"option from the menu. Remove any USB connections that show up there with an exclamation point.

Reboot.
Plug in the printer.
Check to see if you can see a valid connection to this printer.
