Replaced my motherborad, thought that it was bad, I screwed up, it was my power adapter. Now the laptop will not power up. The start button lights up, but nothing happens, and after about 20-30 seconds the power button goes out.

The laptop probably isn't charging. Could be a bad d/c connector on the laptop or the battery is bad. Remove the battery and plug in the a/c adapter and see if it powers on. Wiggle the a/c plug in gently while pressing the power button on the laptop. It powers on and off briefly then I'd say it's the d/c jack on the laptop, bad sodder joint.
Assuming you plugged the power adapter into the laptop and after pressing the power button you have no fan, lights, nothing on the screen.
This could be several issues and sadly most are cheap or easy to fix.
1. Your adapter is bad and needs to be replaced. 2. Your DC jack on the motherboard is damaged (broken solder or pins), DC jack needs to be re soldered or motherboard replaced. 3. Motherboard is bad, needs to be replaced. 4. Battery is bad, remove battery and attempt to power the laptop on with just the adapter plugged in.
Most of the replacement parts can be found on eBay for reasonable prices. The battery and adapter can be tested easily with a multimeter and repalced pretty easy by anyone. The motherboard / jack problem are generally several hundred dollars in repairs from most tech shops.
Honestly I would return the laptop if you have that option available.
One thing to check is to see if the WORPGROUP name is the same.
On your laptop, Right Click on My Computer and go to properties.
Click the Computer Name Tab and compare it with your Dells.
If it's the same then you might want to directly connect your laptop to the router and see if it can recognize it that way.
If all else fails, you can reset the router.
First, you need to make sure your power adapter is providing enough
power to both run the laptop & charge the battery. A very good way
to do this is to compare your laptop voltage & ampere requirements
(written on a sticker on the bottom of the laptop) with the voltage
& ampere ratings of the power adapter. Voltages should be the same,
or the power adapter's voltage about up to 0.5 volts more than the
laptop's voltage rating. Amperage of the power adapter should be at
least equal to or greater than the laptop's rating. It should never be
less than the laptop's rating, or else the power adapter will be
providing insufficient amperes to charge the battery. Of course, the
power adapter's nominal amperage might be ok, but it degraded on usage.
You can verify this by testing using a good or new power adapter. If
the battery did not charge using the new power adapter, take the battery
off the laptop, & using a dry tooth brush, scrub in between the
fins of the battery connector on the motherboard & on the battery it
self, then put the battery back into the laptop & try again. If
this still did not resolve the problem, then the battery itself could be
bad. Try it on another laptop, or try a good or new battery in your
laptop. If this did not work, there might be a possibility that the
charging circuitry on the laptop's motherboard is defective & needs
servicing. In order to do this, the laptop needs to be disassembled
& the motherboard 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
This is the best way to tell. If your system is shutting down on you by behaving like your shutting it down thru windows then it could be a spyware, virus trojan issue going on. If thats the case then run your virus program and see what it finds and remove it.
If your laptop is shutting down on you where everything turns off right away with no lights, kind of like a power outage then go ahead and remove the battery and only use the ac adapter and see if that solves the problem. If it does solve the problem then you know its your battery that is the culprit.
If your only using the ac adapter and the machine shuts off on you like a power outage with no lights then you know its a problem with the motherboard.
With just the ac adapter plugged in, wiggle the cord near where it plugs into the laptop and if it shuts off on you like a power outage then you know its a loose DC Jack and it needs to be resoldered back into place.
Hope all this helps.
the sucky thing with laptops is the electric plugs directly into the motherboard. then the electricity goes from the motherboard to the battery, so i'd have to say the motherboard is bad you could get a new one, but it costs alot of $. So I suggest bring it to your local computer shop and see what they can do.
