Problem with power on
I have been given four IBM M51 (8144) machines to clean up two and have the others if I want them.
So have done up the two to go back to the school and am left with one that seems to work fine, but the other just roars like a 747 taking off when I apply power.
I have tried taking the battery out to reset the BIOS and made sure the CPU was getting power by feeling for the heat coming through - which is does but cannot understand why no boot?
The other thing with these machines is they will only work with the RAM that they came with as I tried some higher capacity RAM that I had and the machines just keep up a double beep and no screen power up. The original RAM is IBM (256 sticks) and I have tried the spare 512 sticks including some IBM stuff I have but still the same result.
I have used all the original RAM for the school machines (1GB each) and am left wondering what I can use in the machines I have left?
These machines are really well built and finished with cavernous cases and SATA connections and I would like one to be another tester and one I can give to a young person who cannot afford a computer.
The boards support Pentiums up to 3.8Ghz and 4GB RAM and seem to be way ahead of their time (2005) and it would be a shame to trash them.
So any ideas on the non power up and what is going on with the RAM issue please??
