Macintosh 165C Boots Up To A White Screen Macintosh 165C

Chosen Solution

I tried to boot up my old Macintosh 165c but it just displays a blank screen. Thanks! Update (05/19/2022)

Do you have the CD drive? Ok here’s how to replace the hard drive: Macintosh PowerBook 165c Hard Drive Replacement Original Mac OS:7.1 Supported Mac OS:7.1-7.5.1, 7.5.3-7.6.1 Details:Earlier and later versions of the Macintosh System/Finder and Mac OS are not supported.

Given no other information, I would go with “failed hard drive”.
