Motherboard Packard Bell EasyNote R6512

Hi Mulder:

Sorry for my English. I'm Portugese working in the Nederlands. I will to do my best to make me understanding.

I thing we are on the good way. My mobo is not exactily the yours, but aproximately the same. I send you 2 pictures of my mobo. do'nt let the electrical wire (i'm trying to read electrical current (voltage) with a 9,5V battery.)

Please try to find or identify the diode and the fuse on my mobo and if it's possible with the partnumbers or values and send me the pictures back with an indication (perhaps a RED ARROW?) on the pictures





Do'nt take care about the electrical wire. It's just to take measure of voltage with a 9,5V battery.

Thank you very much for your help, and sorry for taking your time

Best Regards

Domingos

I will only write my experince which can't be solution but a little information about this problem. The Diode in red circle in my case was short and had cause the Fuse to Ground connection. And so the fuse itself was burn and also the diode.
I have my own question. What is the job of that diode there? Need help with my dead fuse and short diode.

Motherboard Packard Bell EasyNote R6512 - 38ae9ee.jpg Hi Domingos,
Don't worry for your English, I'm french and mine is not so good...

The first component seems to be a diode : what is its indication near it on the mobo ("Dxxx" or "PDxxx" or what else) ? Check its resistance in both direction.
I don't recognize any fuse, and the orther picture is too far (components are too small), but you should look for indication like "Fxxx" or "PFxxx" or "FUxxx". Sometimes, fuses look like green resistor (flat and rectangular) with a cross on it like X. Just behind the diode it's a resistor because there is "R010" on it. However, check its resistance to be sure it isn't grilled.
When you put the power on the mobo, do you find voltage beetwin ground and positive pole of components ?
May be you could resend picture of the other side but nearer.
Hoping this help you...
FM.

Hi Domingos,
Yes you're right !!! PF1 is the fuse and PD701 is the diode...
What are the results from measurements ?
Is the fuse grilled ? And is the diode OK ?
Do you have the voltage somewhere ? or is it shorted beetwen + and - ?
Regards.

Hi Domingos,
I've just changed the grilled fuse and the zener diode which was shorted. The problem is to find where they are on YOUR mobo if it's exactly the same trouble...
At least, did you find the fuse (very often the first component after power jack) ? and diodes are small red or orange glass cylinder with yellow ring.
The fuse should be conductive of course and diode should be conductive in only one direction. For both, check it with ohmmeter, in each direction for the diode (change probes of meter on poles).
If necessary, change compononents : be carefull with diode polarity because it's important (colored ring in the same direction).
I hope this will help you...
Regards
