Difficulty identifying SMD on PackardBell Powerboard

I'm trying to identify a faulty diode on the Charger-board PWA-WEASEL P4/DD_CHARGER BD from a Packard Bell Versa E400 laptop (weasel by name, weasel by nature! LOL)

It's only marked as 34 26 (item PD7 on the PCB legend)

(sorry for sneaking the link in, but without the image, there would be no hope at all of anyone having a clue what I was going on about? :S )

Whilst I know the diode is short-circuit, due to the close proximity I wonder if the transistor marked as 8K C9 (PU1 on the PCB legend) could also be faulty? though it may have an internal diode that's giving me a double reading from base to emitter? It could prove useful to also know what this component is too?

Can anyone please help?

Thanks in advance
