I have an IBM Thinkpad T23, when i hit th power butting the battery and power symbol turn green, nothing shows up on screen, and the fan runs fast then slow the whole time, what should i do. I just replaced the motherboard.
Your t23 has lose parts that need either resoldered or replaced.
you will need to send it to a repair service which is very pricey or replace with another one. new around 199 us dollars or more, or used 70 us dollars at ebay.
I will buy your t23 if you are looking to get rid of it. it has a faulty mother/mainboard with bad solder points. i need the thing for the ic components to repair other t23

Having same issue. how much memory (ram) do you have installed. this model t23 (2647) can only have 256MB DIMM per slot - total 512MB (although it can handle 2X512MB DIMM's) i'd try booting with only 1 256MB DIMM and if sucessful had the other.

Re: T23 wont boot
I would unplug it and remove the battery. Plug it back in and try without battery, if it still doesn't work, unplug the power again and remove the memory (RAM). Plug it back in and try again without RAM, if it beeps then the motherboard is probably good. If you had more than one piece of RAM, try one at a time and see if you get it to boot with one of them.

1. your issue may be a bad hard, a damaged or loose flex cable to the LCD screen, a defective CPU (central processing unit, a cmos battery that needs replacement ( this is the battery that retains the information for the motherboard), a bad power supply regulator on the mother board. 2. this is just a few of the issue that have caused a white screen. 3. Laptops are mostly disposable and are usually good for 2to 3 years of service depending on the care taken. Your friend probably thought he was helping by giving this to you to see if you could use it or part it out. Not worth the work unless you are into PC repair or project work. 2.
My guess would be ;-
A power supply problem with the battery and/or power adapter
The most likely one.
The CPU is overheating and shutting down and if you wait a while and it will power it up again, it will then run for a while and shut down again.
This can be caused by a faulty fan (its not spinning and needs to be replaced) or the vents are clogged with dust (needs to be cleaned and you may need to remove the fan assembly to do this).
do you have a hard drive install??
laptop need a hard drive to start up. the one time start up you see before is just a accident. as far as battery not charge, that is the porblem you run into, when you get laptop from ebay (taking chance). you also need to download all of the drivers from IBM for the laptop.
This is a commin IBM issue fans going Bad ... to try and free it if it's just dust you can actually blow into the vent with compressed air and free up the Fan ... The IBM T series all check fan before powering up.
The replacement is not too difficult to do.
The safest air is the can type to blow in there.
Function F7 will enable the external video monitor connection and will toggle between the screen, the screen plus external monitor, and the external monitor only. Try hitting function F7 and see if that helps. Also there is a small switch that is activated when you close hte lid to turn off the display when the lid is closed. make sure that this little switch is not stuck.
get to the mainboard there is a jumper near the cmos battery usually shows the word (jbat) near it , try to change its position for some seconds while power is off , this way will clear cmos and set the mainboard bios to default settings. start the system hit delete or F2 to enter setup then exit saving changes.
Can you access the bios? If you are able to get a bios screen, the problem is not the processor unless it's overheating really fast. See if the vent for the fan is clogged with dust/hair/etc.
Also, the memory is a possibility.
Instead of swapping it out tho, just put pressure on it in such a way that it's pushed down on the motherboard. These ram slots are known problems. Try it, you may be surprised.
