Question about IBM ThinkPad T30 2366 Notebook
After using the old wedge paper trick for a while the faulty slot that came from the factory finally started giving me trouble. Question: Can the max supported memory on the machine be achieve through only one slot using 1 - 1 GB memory module?
I just repaired my ThinkPad T30 Memory Slot. I determined the slot area buy pushing on the end of the slot w/ my finger during boot-up.
With the RAM cover off and the ThinkPad upside down w/ the RAM slots to your bottom right, the bad pad on this was the one nearest the edge and closest to me. That will be bottom right by this perspective.
I used a Radio Shack Micronta microscope to check the end slot and noticed a hazy area around the contact indicating looseness.
The end contact pad is larger then the others and this may have cause a weak solder joint seeing that the big pad adsorbed more solder and created a thin joint.
I took a soldering iron and sharpened the point with a file and when hot I fluxed the tip and the joint area. Then added a very small bead solder to the iron and touched it to the end joint under a magnifying glass. It created a nice bead on the joint and fixed the problem. I then cleaned the slot with cotton swab and used a needle to check and make sure the pads weren't bridged, but the microscope was enough to validate my solder skill.
I now have 1G Memory! [2 x 512Mb]

Maximum supported RAM even on 2366 is _2GB_ (read: 1GB per slot).
Cleaning contacts of SO-DIMMs with rubber erasers will most likely destroy the RAM due to isolated static discharge. DONT DO THINGS LIKE THAT ! - There are special solutions available for safely (!) cleaning contacts of ESD-sensitive devices.
ESD will not necessarily zap the devices (here: RAM) immediately, more frequent a gradual failure can also occur, which mostly cannot be directly connected with the "small" ESD of the cleaning actions.
Actual Problem (AFAI recall) is mainboard flexing, at least in the last couple of dozen cases I encountered.
Resolder the socket (non-trivial, consult an expert for that !) and all will be fine for the next year or two, then probably another resolder will be required. Additionally the whole machine can be disassembled and one (most likely) blue rubber shock-absorber can be removed. The resoldering will then last for (most probably) ages ...
More information concerning this specific issue on the t30s can be found via e.g. google.com or similar.

512 memory was the highest available at design time. So no additional address lines were made.
So, you must use 2-512 sticks
the wedge paper trick can be eliminated by using an inkpin eraser (gritty type) to clean the contacts on RAM chips.

Tips for a great answer:
When you plug the AC adapter the power LED and the battery charge LED light up. When you press on the power button the laptop powers up but will not start. There is no video on LCD or external monitor.If the power LED lights up it indicates that the laptop is getting power from the AC adapter. Most likely there is nothing wrong with the adapter but just in case test it with a voltmeter to make sure the output voltage is correct.
When you press on the power button, the laptop makes a series or short and long beeps and will not start up. There is no video on the screen.In this situation test the memory module as I described in the situation2. Try installing a known good memory module. Most likely you are getting a beep error because of a faulty memory.
You start the laptop. It sounds like the laptop is booting normally (hard drive LED is flashing) but there is no video on the screenIn this situation test the laptop with an external monitor. If the external screen works fine but there is no video on the laptop LCD, most likely there is a problem inside the laptop display assembly. Go to my previous post witch covers laptop video problems in more details.
You start the laptop and it starts making repetitive clicking noise or grinding noise.Most likely you hear this noise because of a faulty hard drive. You can remove the hard drive and start the laptop without it. If the noise is gone, the hard drive is your problem. Replace it.
The laptop boots into Windows ans works for a while, but after that it shuts down by itself without any reason or warning. You restart the laptop but the same problem appears againMost likely it's a heat related issue. Listen for the cooling fan, make sure it works.
