This is the part number for your motherboard:

91P8862 or 91P7879

Both are compatible with your model.

My laptop IBM ThinkPad 600E 2645 by turning on shows the notice Error 129 in system board. The laptop cannot be put into service.


The ThinkPad error code 129 is a motherboard problem. This is a component failure on the motherboard and cannot be fixed easily.
The 600E is a very, very old laptop. I suggest you don't spend money on it, put your money towards a new or later model laptop.

I am getting an error code of 00161 and 00163 on my ibm think pad 2635


Error code 161 means your CMOS battery is dead and 163 is that system date and time are not set (which make sense as the CMOS battery is dead).
You need to replaced your CMOS motherboard battery to resolved this issue.

Laptop screen displays vertical lines of various colours


Have you tried to connect your laptop to external monitor?
If you get normal picture on external monitor, then you need to replace LCD screen, but if you get same picture on external screen, then unfortunately you will need new motherboard, because graphics card is integrated to motherboard.

Total failure of IBM Thinkpad R50 after connecting sony clie PDA


Hi,
Your colleagues are correct, the problem with laptops is that the motherboard and powersupply are integrated,
if there is a seperate powerboard, usually the mains inlet runs through the mainboard itself to get to it. As it,s located under the touchpad. ( On certain Models )
What you,ve actually done is put an input current into your motherboard via the USB.
These are designed to output 5v pos And 5v negative. + 2 x Data transfer/signal in/out.
If you take this in for repair, you,ll be looking at £75+ Or $150+ Depending where you are. Just to Be Looked At.
For them to possibly charge you an additional £200+ Or $400 for a new motherboard.
Sorry for the Bad-News but i,d advise looking into buying a replacement laptop, and put it down to experience.

Mike @ Compurepair.
