Purr is dead, long live purr...

ewtI have borrowed a multimeter from ![[livejournal.com profile]](https://www.dreamwidth.org/img/external/lj-userinfo.gif)
pfy.
I have taken the laptop apart, mostly. I taped all the screws to a bit of paper in the order I took them out and with labels, so it shouldn't be too difficult to put it back together. Without my housemates tools I probably would have lost a few of the more fiddly screws. He has one of those grabby things with claws. I want one!
Tested power supply and it's putting across between 19V and 20V like it says on the lable. Tested connector - seems to work, no resistance between outside and inside anyway, and when the power supply is plugged into a live socket it's getting 20V on the inside of the case. Should I have tested amperage as well? If it's a connector problem, from what I can tell it's one that will need a magnifying glass and testing of circuits on the board, and I need a bit of help with that because holding a magnifying glass and two contacts for the multimeter with only two hands AND getting the contacts to actally touch very very small silver lines is Hard. Also, with my current abilities there's no way on God's green Earth I'll be able to solder anything that small inside of six months if it does turn out to be the problem.
There was a lot of dust by the fan, like really a lot, and the whole thing smells slightly of fried electronics. I think it has probably melted itself, although I'm not sure which bit it has melted. It had been running a bit hotter recently, I'd thought, but not a lot, and without sticking a thermometer on the bottom it's difficult to measure these things well. My knees aren't terribly accurate for this purpose.
So, it could still be the connector, but I'm not holding up much hope. Sometime in the next few weeks I will be looking for a replacement, but not just now, unless any of you have one that is going for free (or trading for scrap parts, I guess, but I do have projects that want scrap parts from laptops already so this is not as satisfactory, also if you want parts for that sort of project maybe you are willing to have a look at fixing this one, in exchange for a meal or something).

Mine's only a 366Mhz CPU though. It can run video and such. I was plotting to soup the thing up for a video segment on mobile devices. Compaq Armada 7400.

(Most of the rest of laptop bits are non-interchangeable, except sometimes between models from the same manufacturer.)

Things are about to go stupid busy at my end, so do not worry about things being hectic!

Date: 2006-01-03 03:23 pm (UTC)There are only about 5 actually makers of laptops. Sager has been around a long time. Here is a link that might help.

At the same time the unit you have is the laptop that has lasted 2nd longest in my treadmill of units. Likely if the problem is not the power connector at the motherboard parts will be "hard to come by".
