Thanks for the prompt response. The Toshiba L505 is now responding to an external mouse, but not to the touchpad. I’ve checked the connection to the motherboard (seems good) and tried toggling the touchpad on/off using function/f9. Is there a way to determine if the issue is touchpad or motherboard?

This could be software or hardware problem.
Try booting your laptop from Live Linux CD (you can try Knoppix or Ubuntu). When you boot your laptop from one of these CDs, it will take you to a Windows-like desktop. Test your touchpad in there.
If the touchpad works fine in Linux but not in Windows, this is software related problem. Reinstalling Windows from scratch will fix it.
If the touchpad doesn’t work in Linux, probably this is hardware failure.
Which part is causing the problem? I don’t know. Could be bad connection, bad touchpad, bad cable or motherboard problem.

Just replaced power jack on Toshiba L505. When it powered up, there is no control of the cursor with the touchpad or with an external mouse. Any ideas on how to reconnect with the cursor?

Not sure what’s going on but make sure the touchpad cable is connected correctly.
Usually, if the laptop touch pad doesn’t work, you still should be able to use an external mouse. In your case both don’t work and I think it’s somehow related to connection between the touchpad cable and motherboard. This is just a guess though.

how do i take the cover off a gateway lap top to the power port?

All laptops are different. Search though the Gateway category on the right side of this site. I posted some Gateway disassembly instructions in there. It’s possible you’ll find a similar model.

I am trying to re-solder a dc jack in a dell latitude d600. I have to remove the old one first. I am using a weller 40 w soldering iron. it goes up to 900F. Yet it won’t melt the solder. I have tried put new solder over the joint and even used desoldering braid, but it will not loosen. Is my iron still not hot enough?

I’m using Weller WES51 soldering workstation. It has tip temperature control range: 350°F to 850°F and for jack soldering job I set it to 850°F.
