Here in Europe Duo 270c are very rare. I imported mine from USA.

MikeatOSX started following Leaking Capacitors inside PowerBook 500 Series Power Supply, PowerBook Duo 270c - burning power supply, PowerBook 170 concerns and 4 others
-
I opened the Duo power supply by force because the capacitor burned a hole in the case. PowerBook 1xx power supplies have already been (carefully) squeezed with a vice and successfully opened.

You can remove the battery after you opened the 4 screws on the bottom and the smaller screw on the backside near the modem port or cover of the modem port slot. When you move the upper and lower part of the PB a bit there is enough place to remove the battery.

True. And a CF card helps RamDoubler to make the PB 150 fast, when more Ram is missing. -
PowerBook 150: replacement IDE hard disk format pain
MikeatOSX replied to Byrd's topic in 68k PowerBook
I did it again, with my second PowerBook 150: I formatted (again) a Maxflash 2GB CF card in the PCMCIA Slot of my PowerBook 2400c in Mac OS 8.1 (again) with it's Drive Setup (seems to be low level format as it lasts more than 30 mins). Made 3 partions, copied the contents of the PB 150 Disk Tools to one partion and installed the CF card with a cheap CD/IDE adapter in my PB 150. PowerBook 150 started immediately from the partion with the Disk Tools system folder. As PowerBooks 150 don't start in SCSI-Mode (SCSI "Target Mode"), I started a PowerBook 180c in SCSI-Mode and copied it's cont -

Date/Time jumping around on PowerBook 160/165
MikeatOSX replied to nvdeynde's topic in 68k PowerBook
Same here with a PB 180c. Apple Diagnostics app found a Logic Board problem so I replaced the complete lower part of the PowerBook, but with same results. Everything else is working fine. My second PB 180c doesn't show this problem. I solved this problem some years ago by replacing the interconnect board, but not this time, as I don't have a second one. My second PB 180c has a newer chinese replacement main battery, which is still loading fine. Now I try to load the Pram battery on the interconnect board with this working main battery and we'll see if this works. -

I posted this picture 5 years ago here too: I found the original picture 12 years ago here: Your "missing female connector metal in position 4" is found 12 years ago also here:

I measured them all in the past as I told you before. So believe it or not, I continue watching CNN now...
-
I don't measure it now. I have more important things to do now. I did it in the past to find out if there are more than one PB 5x0 power supplies with no power on vbatt+ BTW: I did not invent the expression "vbatt+". I found it on a picture of this power supply in Internet some years ago.

I was in my cellar now: I have 6 PowerBooks 5x0. They all have this missing pin as you call it. On your picture it looks like that there is no metal in the missing pin. All of mine show metal in it.
