Question about IBM ThinkPad T42 Notebook
My IBM T42 thinkpad would not start all of a sudden. The battery and AC power supply seem to be working fine. But everytime I start the laptop, there is a blank screen..the hard drive icon also does not blink.
However, if I persist and try starting it a a few dozen times, some time windows boots up and after a while everything freezes.
I was able to transfer all the data from hard drive through a SATA/USB interface. So, the hard drive is also good. The CD tray also works...so the laptop is getting power.
I suspect the problem is either to do with heat or some internal electrical connection. Would appreciate if someone could point me to some info on things I could try. Maybe a website that explains step-by-step or some general suggestions.
The laptop was working fine till 3 days back.
I need you to try to power it on while you press down firmly (really
press down) in the area just towards the front of the space bar and
just to the left of the touch pad assembly. Hold it down while it tries
to go through the entire power up sequence.
happy! second worked... this actualy work for me it boot it windows normaly, it went to the logging proces as normal, it seems that some cable for the lcd has been lose i dont know can you explain Ron what causes this

And, a good day to you!
To start with, I have a couple of things for you to do so that we can get a little better handle on just what's happening.
First, let's remove the battery, all of the memory (both under the keyboard and on the bottom) and the hard drive. Then replace one of the memory modules in the slot under the keyboard, and see if it doesn't try to come up. Whether or not it tries to come up, go ahead and replace the hard drive and the other memory module and try to bring it up again.
While you have the keyboard out, check the area around the fan to see if it is crudded up with dirt and dust. If so, carefully clean that area.
This exercise may be all that is needed to get it fixed. If not, then continue on.
Secondly, I need you to try to power it on while you press down firmly (really press down) in the area just towards the front of the space bar and just to the left of the touch pad assembly. Hold it down while it tries to go through the entire power up sequence.
Then let me know what happened.

So if "solution" #2 worked, what is really the problem? GPU badly soldered to m/b. If so can it be fixed (without replacing m/b)?

My IBM ThinkPad T42 does not start. No picture, no sound. The battery indicator flickers yellow but no other indicators light up. Took out the battery and tried connecting directly to the mains. Still, the system does not start.
Can someone diagnose and suggest a fix. Thanks/Kumar

There is a common problem with this machine; the mother board flexes and the processor mount partly separates from the motherboad. You tube posts a couple of solutions but they involve taking the laptop apart and applying heat from a heat gun to resolder the mount; it is not a solution for the faint hearted. Thinkpad/Lenovo might consider reparing the unit as it is basically a desgn/production defect but don't hold your breath.

Whops that sounds like a Mother Board Issue Common to IBMs.
What happens when you try to reload the O.S ? I would imagine it still shuts down. If over heats the computer will still turn on but not stay on, will shut down when the sensor on the CPU detectes excessive heat > 75 degrees F .
The problem is somewhere in the Power Supply flip flop Circuit System on the Motherboard most likely but thats academic!
You really cannot "repair" them, only replace them and usually that does not pay; the board costing more than the Computer is worth and Installing it is really a "Factory" Operation.
TIgar has a good selection of Levono Factor Rebuilt Notebooks (hint) lol :)
