Hey All,
Just got myself a nice Thinkcentre A55 desktop tower that has a Celeron D processor inside. I updated the BIOS to the latest version, and noticed that in the notes of the BIOS updates many references to fixes for CONROE (READ: CORE 2 DUO) processors being included. However, I can't find any reliable info as to what processors would be able to be used on this system, but the hardware replacement manual states many Core 2 Duos from the 4400 all the way up to the 6700 as being compatible replacements. I don't know if Lenovo places BIOS locks on specific units to disallow processor upgrades? Has someone done an upgrade on a similar age machine and had issues?
I like this desktop a lot but need some more processing power. The tower came real cheap, the quality is solid, and all I need is the assurance that buying a processor won't be money wasted.
Thanks everyone!
PS: Here is the link to a screenshot from the A55 service manual showing the various procs which supposedly are upgradable on the system: http://xs320.xs.to/xs320/07422/pic_a55.jpg

My opinion is that if the processors are listed in that manual, and the BIOS notes show fixes for Conroe processors, then I believe you are OK.
I personally doubt the "BIOS locks" business in this case, since the BIOS and the manual both mention Conroe processors.
Every IBM I've ever put a processor in, which was newer than the machine could "recognize," worked perfectly (maybe a notice during boot, but that's it...)
... again, these are simply opinions, based on owning a number of IBM PCs over the years, but none are as new as your A55
