View Full Version : Weird problems with Tibook

My tibook has been having kernel panics (Both with the polite message telling you to shut down your screen, and the one where a bunch of code rolls down the screen and it freezes). Also the computer sometimes just plain freezes sometimes and it also just shutsdown randomly. What could be the problem? I don't think its the ram, i tried both sticks independently and it still happens, unless both the ram sticks are bad.

PS: How would i go about checking if my ram was within specs?

The hardware test CD which came with your Ti PB would check up your system. The test also covers the RAM.

I bought the laptop from someone else, it does not have a test cd. And now it freezes at the grey apple startup screen....

Chris - our 400 MHz TiPB has been acting up for over a year now. I basically leave the machine on all of the time and if it does go down I have to boot into safe mode. We are attached to it but are not going to spend the time or $$$ to sort it out as things happen.

My best advice is to start thinking about a new machine - sorry:o
