Yes there is a fuse in the PowerBook 170.  And it is most likely 
blown.  I THINK that fuse blown will give you the symptoms described. 
I got a PB145b for free because it had a blown fuse.  I replaced it 
and all was well.  The following URL has a link for a download of a 
guide for doing the repair.

You do need to be fairly skilled doing electronics soldering to do 
this repair.  The up side  is that the part only costs about $1.

You can HOPE for a fuse, but, from the PB170 (and others) service guide:

Power

Screen is blank;
computer doesn't respond:

1 Press reset switch.
2 Connect power adapter and reboot computer in 3-4 minutes.
3 Try known-good, charged main battery.
4 Check all interconnect board, daughterboard, and
  motherboard connections.
5 Reset the power manager.
6 Replace keyboard.
7 Replace interconnect board.
8 Replace daughterboard.
9 Replace motherboard.

Good Luck.

Ken



Use it up, wear it out, make it do or do without.

no-go powerbook 170 newbie-followup

[EARLSW]

AHA!  It now appears that the person who gave it to me tried to plug in a
20v power supply.
Not GOOD!
Is there a fuse in a Powerbook 170?

THANKS!
Scott Earl

>>Hi All!
A friend gave me a Powerbook 170 that won't go.
I charged up and recycled the battery with a conditioner and it holds a
charge, but the Mac doesn't do ANYTHING when I press the start button.
There is no hard drive, but I don't think it would need one just to bring
up the screen and ask for a disk.

I don't have a power supply.

The unit is in remarkable appearance condition, but that doesn't help.
Should I just sell it on eBay for parts?

THANKS!
Scott Earl
