Thinkpads Forum

Hello All,

I found out today that the female ext. mouse connector on my thinkpad may be broken free from the motherboard. The connector moves around too much when a mouse is plugged in for my liking, and windows does not see the ext. mouse when plugged in. I am going to pull the motherboard out and see if it is just broken solder connections, like I've fixed a hundred times before, but if the connector is broken, like I've also seen, I need to find a source and part number for a replacement connector. Anyone have any suggestions?

Lastly, a question that has been bugging me.

I'd like to upgrade the processor from a 700Mhz to one faster. I have been told that you can't upgrade the i1300, but is that just because the processor is soldered on? Why can't a person with years of soldering experience just get a faster Celeron processor and replace it? Is there something about the i1300 processor that makes it unique to the point that no other Celeron processor in the world will work in it's place?

Thanks to all who reply,

If you have an iSeries, you can't upgrade any single components (except maybe add the internal NIC or Modem) since the parts, including PCU are soldiered on the motherboard. According to the IBM tiwbook.pdf file, the fastest i1300 made ran at 750mhz so mabe you could get a 750mhz motherboard but I don't think the extra 50mhz would give much advantage. You also have can't use the motherboard from a 12" model with a 13" screen and vice versa so be careful about that when geting a new motherboard.

If you need part numbers for specific parts, check the Hardware Maintenance Manual listed in the FAQ.

This is my third attempt to post a reply! I hope the other 2 don't show up after I post this one1

AK,
My question is, if I can desolder my processor and replace it, (which I can), Will any 1.?Ghz Celeron processor work as a replacement? If not why not? How about a 1.?Ghz Celeron processor from a different laptop?

In theory, you should be able to desoldier the old CPU and resoldier any 100mhz bus TCP Pentium III or Celeron but I doubt it'd be successful unless you are very good at soldiering and have very good professioal equipment. It'd also be a challenge finding a chip to soldier on since you can't use a normal desktop chip. If you were to upgrade CPU, motherboard replacement would be the only practical solution for the computer, unfortunatley.
