Broken charger - safety concern question.

So here's the deal

my laptop fell off with the charger plugged in. Laptop is in great condition. The charger however, had it's plastic/rubber housing cracked open. I could see the raw cables inside it. Currently, it's being held with duct tape. Lots of it.

Query: is this okay? Electric tape is an option of course but I put in duct tape first just because I didn't have any on hand.

Charger still works as intended. I am looking to mod it [add a switch] or remove the center pin to not underclock my incoming 920xm with the 7970m already in.
Can I also find a similar finish somewhere and reapply it on to this one?



Note: incase I didn't mention, the plastic that cracked open is the plugged to the laptop port.

 

I wouldn't take any chances. If the wires look good inside, then seal the crack with some epoxy resin or similar. However if you intend to overclock both 920xm and 7970M then why not use this opportunity to buy a 210W or 240W PSU and keep this one just for charging the battery.

 

Never tought to use the resin. Thing is this crack is basically the whole thing split apart. Only reason it held when it did was that at the very tip of the metal jack is where the split ended on both sides. Would epoxy sealing work? Pardon the ignorance but how exactly?

Regarding the mod - I remember reading in one of the threads about just putting on a switch for when you need it to charge/OC. I don't intend to OC the 7970m. Stock clocks at .95v is more than enough. I'm using the 920xm just to get past the bottlenecks caused by my 740qm. Even then, from what I've read in this forum - the 150w is just fine. a 210/240 would still result in an underclock mainly because of a hardware/board level limitation or something of the sort. It was on a post by King of Interns [shoutouts!]

 

It would help to see a picture if possible, even from smartphone, of the damage.

You can get a Dell L-adapter and pull the centre pin from that, then use the adapter for gaming as it won't charge the battery. You will eventually want to overclock as games become more demanding so I suggest considering a 210 or 240W PSU now. All PSUs are power-limited and result in throttling unless you pull the centre pin (or use the L-adapter without centre pin). My 7970M would throttle if I touched the CPU clock speed even slightly, until I pulled the centre pin.

Noticing a general theme here? Pull that centre pin!

 

Yes a picture would help, does it rattle if you shake it gently?
