There is not so much that could be done to repair a keyboard. Disassemble the laptop, check the ribbon cable connecting the keyboard to the motherboard. If the ribbon cable is loose, tighten it. If it is tight, replace the keyboard with a new one.

    Sorry. I pasted the wrong text into your problem.

    Here is the correct solution:

    This could be a sign that your laptop is overheating. If you touch the laptop while it is running & you find it too hot, make sure that the fan is running properly & that the air ways are not blocked.
    You can blow compressed air into the cooling vents of the fan. If you notice clouds of dust coming out, then it might be a good idea to disassemble the laptop, clean the fan & air ways, & reassemble it back. If the fan has failed & is no longer running, it might need to be replaced.

    If none of this solves the problem, or is not the case, then you might have a bad motherboard.

When i switch on my IBM thinkpad R51, it displays the THERMAL SENSOR ERROR and then it shutdown. Where is the location of the sensors are on the motherboard.

Usually under the CPU, but it appears you may have a faulty fan/heatsink or its not working at all, if you can direct a fan at the thermal vent and it stays on longer then that will be the issue, i would recommend taking to to a local repair tech unless you can do it yourself.

Most likely problems:
Wrong sensor set in the media type area. Gap, Reflective.
If the incorrect meday sensor is set, the unit will give a TOF error.
If you hae pressed the feed button and kept pressed for at least 4 labels, and it does not automatically calibrate, check the type of sensor.
If you still get error, and the correct sensor is set, do a complete calibration.

IBM Infoprint 1532 giving error code 922.14 -service fuser error

There is a heater control problem in the fuser.
The fuser is the assembly of heated rollers in the rear of the device.
The most likely cause is either a blown heater element, or perhaps a faulty temperature sensor.
Usually we fit an exchange fuser assemblt to fix this.

Don't worry. I'm sure it will be fine, as long as it's not over heating or smoking. lol. But seriously, you should be able to disable that error in Bios under one of those options. If you are still having problems contact customer support for help.

Error ribbon in is flashing in Z4Mplus printer althought its set to direct themal

this shouldn't stop it printing, could be a dirty sensor - under the printhead. it is a printhead open/ribbon sensor. try giving it a clean (its not the red one). if that doesn't work you can turn the ribbon sensor up to 100% in the menu. that usually stops the error if all else fails
