Hi everyone, good morning!
I have got an HP Omnibook 430 notebook, is a really nice machine with a B&W passive screen and a really curious mouse. We can found a bit of information here http://www.hpmuseum.net/display_item.php?hw=228.
I will try to repair it, it seems that will be a big challenge. The old capacitors have been removed from the power supply section of their mainboard, and I don’t have any idea about their values or polarity.
Does anyone have a photo of the mainboard or the values of these capacitors?
Another possible problem is that I have seen three capacitors that look like cell batteries but with a weird voltage and capacity. They have a little label that says ‘5.5v 0.22F’, it the first time that I see one of them.
Any info or recommendation is welcome. I have already download the service manual, but it doesn’t have information about the electronics of the computer.
Thanks in advance!
