That's a resettable *thermal* fuse, NOT a fuse designed for overcurrent
protection.

I had always thought that at least some polyfuses /were/ resettable.
Regardless, thanks for the answer.

Nigel,

Also keep in mind as a possibility that the main filter caps are
getting tired, and a bit leaky, so that if the amp has not been switched
on for a week or 2, it might have abnormally high inrush current as the
caps charge/form back up.

Lastly, the older 'spring wire' fuses seemed more tolerant of the
inrush current compared to the modern chemically treated wire ones.
Maybe use an old style fuse, if you can find one.

It would be helpful if you would mention the make and model of the
product in your posts.

Believe it or not, I've found them more often in 'outlet' or 'job lot'

Yeah! And take a video for us to see what happens when you power it up.
Extra points for audio. Make sure you use a 600W or better supply,
fold-overs just won't cut it. ;)

From: jaugustine@verizon.net

Hi,

I service TVs, etc. Once in a while, I service my own computers, one of
which is a Compaq Presario 1230 laptop with Windows 98se I bought second hand
a few years ago. You may consider this obsolete, but to me, it is very
useful.

Recently, during power up, I saw "Error, O2BO: Diskette drive A error".
I removed the floppy drive, but I got the same error, which could be
it's controller?

I inserted a bootable CD rom hoping that the boot sequence might start at
the CD rom, but it didn't. It must be A: drive first. Note: The HDD is fine
because I removed it and checked it on anther PC.

If I can change the boot sequence, I can do without the floppy drive,
but to get into the settings by pressing F10, I have to enter a password.
I don't have the phone number of the person I bought it from who lives
out of town.

I removed the RTC/CMOS battery (soldered in) and waited 24 hours
hoping that it may "clear" the password requirement, but it did not.
Maybe I should wait longer?

Pressing F10 presents a screen that says, "Phoenix BIOS Setup Utility"
followed by a prompt for a password. I tried some by guessing, but it
didn't work. I hope the password isn't stored in the BIOS.

Do you know a technique to bypass the password requirement so
I can change the boot sequence?

Thank You in Advance, John

PS, Remove "ine" from my email address
