Re: T22 Error 0175/Bad CRC1. Looking for an eeprom dump.

I've tried to edit my current eeprom by comparing with an uncorrupted eeprom from a Thinkpad A21 but with no success If you truly tried to use an A21 EEPROM dump to revive your T22, then I think that's your problem. I believe that the systems are too different to share BIOS firmware. If on the othe...

Re: T22 Error 0175/Bad CRC1. Looking for an eeprom dump.

Welcome to thinkpads.com!

Am I to assume that you have a way of re-programming the EEPROM while it's still in circuit, or are you attempting to do this with it removed from the motherboard?

Re: RAM frequency vs. power consumption for Carolina idiots

Here's my take on this, from years (decades, even) of a memory test engineering background. Given that the memory clock speed is kept constant in Thinkpads (I'm assuming that all current and past designs do NOT adjust their clock speed when presented with memory modules that have a higher speed rati...

The first reference that comes up with a "intel t7600 cpu pinout" Google search is this:

Section 4 lists the pinout, although there does not seem to be any documentation about undervolting (done by searching the .PDF).

To be clear, what system are we talking about here? T2x cannot implement P4 so I'm assuming that you are doing this on a T30. If so, then it's likely that the missing (dead) battery is preventing the system from running at full speed. Try installing a known good battery and re-measure the system spe...

Re: 15,1" T60p with non-IPS display?

I'd lean toward the MTM lookup being correct. If the system has a T60p nameplate on the bezel, then it's possible that somebody either swapped the entire lid assembly, or slapped on the wrong clear plate (the plastic strip over the indicator LEDs).

The danger doing that is that when you are removing the jack you cause some damage to the mothe...
