- [reposted due to news screwup - sorry if you've seen it]
-
- Sorry to hear of your problems.
-
- Regarding your freezing problems, I have a similar (but not so severe)
- problem with my PB170. When the Command key is pressed too hard, or
- the case is pressed in the vicinity of the mouse, horizontal lines
- appear on the screen, and the machine may freeze. Sometimes, pressing
- again will unfreeze it.
-
- I have been advised that this is caused by a defective oscillator
- connection or trace on the board, and that flexing the motherboard (by
- pressing on the case) causes intermittent disruptions of the system
- clock (or maybe the display sync?).
-
- I took this to a dealer, who claimed to have knowledge of this
- problem, but they couldn't repeat it. The problem did go away for a
- while, presumably because they re-seated the boards, but now it is
- back.
-
- I like the machine, but it does have some problems. Another one that
- you didn't mention is the lousy power supply. I had to downgrade from
- an 80MB HD to a 40MB because the power supply can't produce enough
- peak current (> 2.0 Amps) to spin the drive up AND run my color card
- at the same time.
-
- And what about the heat the thing makes.
-
- Good luck.
