So I have this laptop, I inherited it from my father (he got a new work laptop). Everything was fine until the AC Adapter shorted and I tried to fix it

I had an old 2-pin charger with the right voltage and amperage but it didn't fit.

After doing research on google I discovered the 3rd pin was only used to ID the adapter as being original(simplified). I cut off the 3-pin connector from the shorted adapter and found a diagram telling me which wires were ground and which v-out. I connected them and nothing...

 

So I swapped the wires figuring I had connected wromsinfo32.txtng *facepalm*...

After plugging the adapter into an outlet and hearing the distinctive noise of something being shorted and seeing my laptop screen go dark. I unplugged and tried turning it on again, nothing....

My dads new work laptop luckily used the proper adapter and I was able to see that the laptop was in working order... mostly

 

The battery was not charging so I figured it was ruined and ordered a new one. (In windows it said "Plugged In, Charging, 4%" but it never gained any charge, not while sitting idle or turned off)

My dad permanently borrowed some adapters from old laptops at work and I got on with my life expecting the new battery to fix everything.

Only it didn't. I received the new battery today plugged it in and nicely surprised when it arrived charged to 34%. After playing for a couple of hours(plugged in) I checked the battery level and it was saying "Plugged in, Charging 34%". It hadn't charged, so I decided to see if I could play on battery alone and I could.

Since then I have tried a variety of fixes:

• Uninstalling the drivers in Device Manager, then searching for hardware updates
• Uninstalling the drivers in Device Manager, then restarting
• Power off, remove battery, hold power button for 1min+ (to deplete an internal battery)
• Cleaning the battery connectors
• Trying different AC adapters
• Booting a Ubuntu Live DVD to see if it was a windows problem
• Disassembling the laptop to check the soldering on the battery connectors

 

TL:DR; Tried to fix my laptop adapter - fucked up my laptop

 

Next step, venturing into the BIOS

 

Any suggestions appreciated
