Once agin, thank you. Is the one on the right only for the USB? Do I need to reflow the laptop or is it something else? The laptop screen has started flickering. I managed to solve that problem by putting RAM in to a single slot instead of both the slots. I have a certain problem booting my fnr. United States and many other countries See details.

But laptops touchpad doesnt. The DVD drive spins, so it gets power from the motherboard.

I have a certain problem booting my fnr.

I am now looking for a replacement mobo. Do you think it would be possible and worth trying to replace the power supply? This page works best with JavaScript.

Remove four screws securing the display panel. Is there any reason to think resoldering anything will fix this motherboard? Evidence indicates the problem is the GPU chip overheats long, hi-demand video display due to inadequate cooling in that area and it de-solders a connection. I have done some researching and it seems that it might be because of the power jack is bad so I thought I would buy one off ebay.

You should be able to find a part number for this cable in the official service manual. My online research thus far has been completly unhelpful with possible causes ranging from the mother board, to the hard drive, to the battery. Drain the battery completely dead with the Presaro switch in the ON position. Boot from the Vista installation CD.
