DC jack, where you plug the power adapter cable, might be loose or
defective, & needs to be either re-soldered or replaced. In order to do this, the laptop needs to be disassembled
& the motherboard taken out. Also, the motherboard needs to be checked for defective/burned out components in the
area near the DC jack. Any defective/burned out components found should
be replaced, or you might need to replace the laptop's motherboard
Unless you've got solder skills it's best to let a local tech do it instead. Going rate used to be around 100 but prices have dropped in certain metropolitan areas. The lowest I've seen someone do it for was 45 with part included! Try craigslist or this site for a local tech near you.
for model TM4151,
1. you need to open the power cover (power cover is cover where power button is).
2. remove screw that hold keyboard.
3. after you remove keyboard, you will see the screw that hold dvd (it's under keyboard)
You might of fried the whole motherboard when it sparked. Check if there is a fuse. Bridge the gap, and it should turn on. If not PULL THE PLUG.its something else that went wrong.If you don't, it smells really bad. Ive learn't from experience...
Do u know to use Soldering iron...if u know..remove the proccessor from socket then de solder the BIOS batterry and short that two terminals on mother board without connecting the power adapter and battery...do it and re solder the bios battery..this procedure will help u to recover from ur problem..if u dont know then do it with any technician.
