laptop power supply

I hav e a older hp laptop the the power plug in the back has become old and failed. i got it checked out and was told that i would have to replace the motherboard./ since then ive replaced the laptop. now i have the need for a laptop at work though (nothing special just to run some basic stuff on. ) i was wondering if it is possible to connect the power cord to where the battery would be? the battery is also junk. would that work? i havent checked out the power rating of the power supply and compared it to the batt, but it should work since they both power the same unit. also, the battery has multiple pins, compared to the standard + - of the power supply. any ideas on how to do this?

That battery packs contain electronics to prevent overcharging. You'll have to find out what the real plus and minus is. You will need to find out whether the battery voltage is the same as the power supply. If that's ok you may try to connect the power supply via a kind of a dummy battery. As you do not connect the battery pack electronics the system may refuse to work with it. Do not use the battery itself because the overcharging protection will not work. Worsed case the battery may even explode.

Someone told you to replace the motherboard. So helpful. Not.

I never opened a laptop so I don't know what skill level it takes to repair the solder joints on the power connection. You might want to try it. Or use the battery case terminals to connect another source of power to your laptop. It will likely run on anything from 12 to 15 volts. A battery provides cleaner power than a power supply (hint).

Would it be possible to open up the laptop, remove (unsolder) the broken power connector, and replace it with acouple of wires ? Then you could put a convenient plug on the wires and use a suitable external supply. The manufacturer's website might have usefule dis-assembly instructions, or a local laptop repair shop. That way you aren't mucking about with the regulation / charging circuits, which seems safer. It might just be that the power plug is mounted on the board in such a way that many plug/unplug cycles have made it move a little, and the solder links to the board are cracked/broken. In this case you might be able to effect a repair. Some Amstrad computers were prone to this. hth Neil

they can be fixed, but it's not cheap. laptops are like 3d jigsaws and to take the motherboard out you have to pull the whole laptop apart...

I know somwone who's a reasonab;y experienced PC technician (but not laptops) who took on such a job, it took him all day.

it might, it might not work, it might damage something.

i already have pulled the entire thing apart. i expected it to be a broken connection of some sort, but didnt know exactly what to expect. the connector for the power supply is a large plastic connector that is placed over the soldered connections. to get to the connections i would have to "bust" this thing off. all in all, im not looking for anything pretty, just reliable. i work in a shop (automotive) and i just want something i can connect to the net with and run out information system on. ill have to look at the voltages and everything printed on both the battery pack and charger.
