My IBM 755CD arrived today.
I purchased it from eBay NOT working.
It turns out it is all intact it just has NOT been turn on in a long time.
So I plug in an AC Adapter and powered it on.
It started to boot but the screen remained Black.
I could see that the back light in the screen was working just NO picture.
So I opened up the lid of the thinkpad and looked under the hood ( keyboard ).
I could clearly see the Floppy drive, Battery, and Hard drive.
Everything looked good at first but then on closer inspection I could see corrosion by the battery.
So I removed all the removable drives and battery.
The Battery was heavily corroded on the bottom.
So I cleaned the corrosion with vinegar and let it dry.
I then tried to start the thinkpad but it does not post now.
I do not have a battery installed as it is an old battery type that I do not have a spare of and I can't find one online.
Is the battery required to boot this computer ?
What do you think could be wrong with this thinkpad ?
It started to boot when I first turned it on just no picture.
I think the display is good. Might be a cable problem ?
