I found my dad's old laptop the other day in the basement minus the charger. Before I go spending money on a new charger I'd like to know if the laptop works at all. Anyone know which side is positive or negative on this style plug? I've never seen them myself. Its a Dell Inspiron 9300 by the way

You can buy the cable heads online for a few dollars, or if your feeling dangerous just pull out the connector and attach the wires to the mobo. That's what I did with my old spare laptop to make an always on music/entertainment system for my dorm.

If you are going to use a non dell charger ( w/o the ID line ) you are going to get unrecognized charger warnings on boot. You just have to tap f1 or something and it will slow charge.
I was thinking of just alligator clips onto the side or something seeing if it even works and the buying a proper charger if it does work. I guessing the side towards the vga plug is the positive then?
There are no sides, there's the inner pin, outer contact which is negative and the inner contact which is positive.
Yeah I sort of noticed that just now....any way I can jury rig something to just turn it on?
You could take apart the laptop and solder the cables to where the plug connects to the board.
It's cheap and dirty but it works.

Don't really want to do that as I'm interested in using it as a normal laptop if it does work
That's the only way i can see of being able to get around that connector apart from buying a charger.
I wonder if I could get solid core wire to just rest on the contacts just enough to turn it on

Having around 80 watts going trough a bad contact surrounded by plastic doesnt seem like a very good idea.
I have seen laptop plugs melt from bad contacts with the original plug.

We see this all the time at work. Someone buys a universal (multi tip) laptop charger and uses a plug that's slightly too small, comes in with a melted socket.
I suppose I could buy a charger and return it if the laptop doesn't work

If you're in the UK go to your local Maplin. They'll have no problems letting you test one of their universal supplies in store.
Thanks but I managed to get one from a friend. Laptop works but the screen has vertical lines down it
Can you take a picture of the screen with said lines?
They're like this but more on each side.

They stay put no matter what I do...moving the screen, lightly pushing on them...I'm guessing its either the connection or the screen itself. Mine are also skinnier...I'll get an exact pic when I find my SD card

If you plug a screen into the VGA port, are the lines there?
It looks like part of the screens logic board is fucked.

Looks like a pentium M dotty.
not worth repairing IMO.

You might be able to part it out though.
Its caused by repeated openings of the laptop lid from the middle of the screen, eventually that action screws up the screen. You could try packing out the back of the screen at the top near the latch as sometimes that resolves the problem.
No lines if I plug it into a external monitor

Packing out?

putting stuff behind the screen or in-between the bezel, to put pressure back on it the other way.
I don't think thats issue as I've already tried applying pressure to the screen to avail and the screen case is very thick therefore I don't the screen flexes at all when opened
