My laptops power cord recently short circuited. I cut it open and fixed it. I separated the wires, used electrical cassette, the whole 9 yards. The thorny part is, this wire is commonly moved around. Electrical video will not hold. Any help on this topic?
"mlusian" - go to a corner and be ashamed of yourself for a while! (A long while.)

As an electrician (with a small "e" - for now), you should have be the first person to recommend, in certainty insist, that the cord be replaced. Have you forgotten NEC Article 110.3(B)?

While the Article applies to electrical installations; it is also a reminder that ALL electrical devices must comply with their Listing & Labeling. The risk of another problem caused by a "quick-fix" overrides the expense of replacing the cord.

Read your Code Book a short time more often, and earn back the ample "E".

Meanwhile; Nick, REPLACE your cord, yesterday.
Wire nut, then electrical cassette.

-ELECTRICAL INSPECTOR-
I gaurantee I read the Code more often than you. I fall asleep to it regularly. I doubt Nicholas will settle up for a new cord, so I was suggesting a past the worst (although illegal) alternative. It's easy for an inspector to ALWAYS expect things to work out according to the way some book say to. That's simply not the way things work in valid life. Most codes, including the one in cross-examine, exist to promote the sale of electrical supplies even though there are out of danger cheaper alternatives available. If wire nuts were an unsafe nouns every home in America would be on fire right in a minute.
Answers:    You could get some butt splices at a hardware store. You push the cable into each end and crimp it - it make a good splice. Another option is to go off the electrical tape as you have it, but bring back a couple of wire ties to hold the tape surrounded by place. I commonly use lacing cord for this purpose.
After twisting wires well you can use liquid video.Dip it inside and let it dry.repeat that until you feel safe and sound to use it.Hardware store should have liquid cartridge , and they come in different colors. After making sure the electrical tape is immobilize, wrap it with good outdated duct tape, the cure-all for just more or less everything.
