Storage Auction Recovery- (This unit was very well kept, a retired electrical engineer, with no family - more to come). 1 IBM THINKPAD 755C, With set of two keys to unlock unit, Built-In speakers, and original power cord. * The second time I tested this unit, the right speaker started to hum tapped it, it stopped. Third time good to go. I am not an expert or collector - The extent of my technical knowledge is that it powers up, as you can see in the first photo. Please review photos and ask any questions. All sales are final unless you have been misled. A+ seller. GENAZ LLC. Thank you and God bless!
