Ibm t30 post beep error 1 3 3 1
T30's do have a well reported problem with their memory slots. It is possible to fix it if you are brave and moderatly competent with a low-power (15-20W) soldering iron with a good bit (I recommend a flat oblique tip of about 2-3mm, not a pointed one).
Firstly, heat the soldering iron and clean all traces of solder from the bit. You can use a wet solder sponge, or even damp kitchen paper. It is VITAL to remove all solder.
Remove power and battery from the T30. Open the memory cover, and remove all memory.
Taking great care, press the bit of the hot iron with moderate pressure (about twice what you would use to press a key with one finger) on each pin in turn for about 1 second, on the contacts of the memory slot that is not working. Because you have no solder on the tip, it does not matter that you touch more than one contact at a time, but there are very small surface mount capacitors between the sockets. Be careful not to touch and unsolder these.
There is a warning here. Do no wipe the iron across the contacts. Always lift the iron before pressing it on the next pin(s). If you do wipe iron across the contacts, you WILL bend and short them. These are surface mount components, and the wire contacts are easily disturbed and shorted. If you do short the contacts, it will be difficult or impossible to fix.
Remember there are pins on both sides of the memory socket. Do not worry if some of the plastic of the socket melts, it is not a problem.
Continue until you have worked on all of the pins. Patience is a virtue here. Allow to cool, re-assemble and test.
I cannot promise that this will fix your T30, but I have extended the life of 2 out of 3 T30s I worked on in this way. Note extended, because the design flaw will cause the problem again sometime in the future. The board appears to flex, which puts strain on the solder joints.
