Have you checked the power settings in the BIOS set up? There are ways to automatically turn off machine there.

Pc turning off


Be more specific. Turning off when? What happens when you try to turn it on? When you have the power cord plugged in do you see any lights? When you press the power button do you hear the fan running, hear the hard drive running, see anything on the lcd screen, hear the cd drive Click once, see the light on the cd drive drawer turn on for a second or two when it clicks, hear any beeps or blinking lights?

My ibm thinkpad won't turn on


Try powering on laptop what happens do you hear any beeps or see any lights normally if u see lights this is a sign that it is working if not your motherboard could be bad if you see lights and hear constant short beeps this means your memory can be bad, Try powering on laptop without battery and only power supply plugged in.

I have an old IBM Thinkpad A31. When I power on, I get the IBM Thinkpad logo on screen, the fan turns on, but after about 15 seconds I get 2 beeps and it shuts down. I suspect that the hard drive is...


Hi,

2 short beeps actually refer to RAM. If you are comfortable re-seating the RAM to it's place, then do it. If you still have the same issue, then it's the motherboard.

A click on YES will be greatly appreciated. Thank you for choosing FixYa!

Hello my laptop t41 power is not even flash but the adapter is working,am technician and i have troubleshoot allot.


I concur with what Diegotech stated.

To iterate further;

1) The DC Power Jack (DC IN), may have cracked solder joint/s on the motherboard connector, (Female), where the DC Power Jack plugs in.

Resolder

2) The DC Power Jack may be broken.
Center Pin mount, and/or body of DC Power Jack, and/or Outer Shell mount.

Replace DC Power Jack.

3) Wires from the DC Power jack plug to the female connector on the motherboard, may be bad.

Replace DC Power Jack.

Two examples, of a place to buy an IBM ThinkPad T41 DC Power Jack,

1) http://www.buy.com/prod/dc-power-jack-connector-socket-for-ibm-thinkpad-t40-t41-t42-r50-r51-r52/q/sellerid/23962916/loc/101/215782035.html

2) http://www.machinaelectronics.com/store/buypart/IBM_Thinkpad_T41/DC-P001

Past this point it's a bad DC sensor on the motherboard.

Replace motherboard.

Laptop IBM ThinkPad. Black screen. Short beeps: 1+3+3+1


Hello,

You can try the following steps:

1. Unplug the power from the laptop and remove the battery then press the power button of the laptop for 15 seconds

2. Put the battery back in, turn on the laptop without plugging the power to the laptop (If this didn't resolve the issue)

3. Remove the battery and press the power button of the laptop for 15 seconds, after that, plug the power cord and turn on the laptop (if this didn't resolve the issue)

4. Remove the power cord and press the power button of the laptop for 15 seconds, disconnect the Hard drive and turn on the laptop (If this didn't resolve the issue) reconnec the hard drive

5. Remove the Optical Drive and turn on the laptop (If this didn't resolve the issue) reconnect the optical drive

6. Remove the memory chip, if you have 2 memory chips installed in the 2 memory slots (remove both of them) now test each one of the memory to each slots turning on the laptop. (If this didn't resolve the issue) Put the memory chip back in. (Clean the slots if there are large amounts of dust)

7. Reseat the CPU and try to make sure that it's installed properly. Turn on the laptop and test if it's gonna work (If this didn't resolve the issue)

8. Reseat the power cords coming from the power supply of the laptop and test the laptop. (If this didn't resolve the issue)

9. Disconnect everything and just leave the CPU installed and turn on the laptop.

10. If all else fails, there's a big possibility that the problem may be with the power supply or the motherboard of the laptop.

Forget BIOS Password (Laptop - IBM Thinkpad Lenovo R60)


For that you need to reset factory defaults settings for bios.
For reset bios u have to open back side of your laptop then u find motherbord circuit there.
pull cmos cell on motherbord for 15 minute then it reset to defaults.
Also u can reset with jumper settigns read carefully on mother bord there is 1 jumper near cmos cell u read there " bios reset or clear"
It is on 1-2 position right now set it in 2-3 position then power up then all bios settings are reset.
then again set it in 1-2 its original position.

Also, have you changed anything lately? and, Did this just start happening out of the blue, or did something happen to cause this, ie... power failure, kicked the plug out, ran the battery completely dead, overheated, etc...?
