My Packard Bell Easynote MV51 had a problem with the power connector.
I decided to replace it and removed the dc and usb board. In the process I noticed that there was a small black box on the board with 4 connections, the box being about .25"x.125"x.25". This had a click on lid that had come off and was broken, maybe due to my clumsiness. Inside is a small coiled spring and contacts. Problem I have what is it??? I have assumed it is a thermal trip or fuse of some kind. But I can't see clearly how it connects on the board with the four pads. They appear by continuity check to be connected in pairs, but it isn't obvious where the board tracks go.

As I said what is it, and how does it work??
Is it only a two way series device. ???
Can I short it out temporarily to check out my new connector replacement??
Can I get a spare or can I replace it with a thermal trip/fuse of standard type.

Hoping help is available.

Thanks for the reply Joeten, the link you gave looks useful for the future, but I think they only seem to cover mother boards. The component I am querying is on a small satellite board called the DC board in the PB repair manual. Schematics would certainly be useful if anyone has them.

Regards

Like to resurrect this again. Had no joy with the Packard Bell support site, say that they can examine if suitable for repair for £55 shipping charge. I notice on another view of the DC board on another model that the component in question is left out.

Can no-one help out there???? Can I buy schematics of the dc board anywhere and does the dc board also do power supply regulation or is that somewhere else???

Thanks for reply, I'll follow the schematic diagram ad up' though if its just one page I don't think there would be enough detail in it. I'll query them anyway!!!
I already have the service manual from the web which is certainly very good for disassembly information.

Hi that was all I found and it rankles because they are a charge site and I would not wish you to pay for it, I will keep looking for a free one but it is a difficult task as PB do not seem to release much in that area
