OK, I have opened a new thread specific to the replacement of the inverter on a spare Packard Bell Easynote F7305, I have found an inverter that would work, but then I found this note by the description, seems to make things a little complicated than it should, Im not sure if its the inverters this place make, or if these are the official inverters, or if its a bad batch.
But kinda throws me out of the idea of doing it, what you think?

Code:
# Known problem with systems that use these inverters:
# There is no point in just putting the replacement inverter in if the system is faulty, so we have included this little tutorial to help you get it all back
# These inverters have an input voltage which is supposed to be 12v, however it has come to our attention that there is a known problem with some systems that use these inverters and they are supplying power at high a voltage, some have been known to give up to 15v
# NOTE THIS IS PIN NUMBER ONE AND TWO
# The best way to bring this voltage down it to put in a silicon diode inline, or how many you need to bring it down to the correct voltage
# EACH silicone diode will bring the voltage down by 0.65v, so if you need the voltage down by 2v put in 3 if you need it down by 1.3v put in 2 etc etc.
# Part number of the silicone diode to put in is in4002, 3, 4, 5, or 7. order at this link
# these are polarity specific, so the side with the band should be to the side of the inverter
# if you have this problem use the links to order the diodes
# If you are one of the really unlucky ones and you have an output of 18+ volts, (no wonder your old one blew) then you need to use the ZENER DIODE 1N5337B this will bring the voltage down by 4.7v use one of these and whatever you need of the above ones to bring it down to the correct voltage order at this link
# use the above link to order them online they are only a few pence
