Disassembling 65 watt power supply #LA65NSO-00

Question

Me and a friend have identical Inspiron E1505s.  His power supply died and was replaced, and Dell didn't require return of the old one.  I'd like to take apart the old supply and try to get it running again so I/we can have two supplies.   Some supplies on older computers were fastened together with the screws under the label but I can't detect any detents under this supply's label.   Has anyone taken apart this power supply?  How is it accomplished?   Why does the forum software prohibit posts with the word S.C.R.E.W.E.D in them?  Seems a bit big-Brotherish to me.

Well, as far as I know, they're actually made to not be openable. That's why Dell wouldn't take it back. I could be wrong; check out google. They may have something...

They have put filters on messages and that is a filtered word. It happened to me with a typo. I wanted to write so that in a phrase, but I have put the space after t by mistake. Consequently, I was proposed to change my post...! Sometimes it is good, sometimes it is not...

Anyway, let's go back to the topic. You should be careful when repairing an adapter. The risk is to make a laptop become a furniture. ;)

You do NOT want to open a Power Supply, much like desktop power supplies you will most likely get electricuted. I would not suggest trying to get this working again, just toss it in the trash.

Wow.  If Edison was worried about being electrocuted we would not be having this conversation.   I've opened supplies before and re-soldered broken electrical leads.  I've opened toasters, and radios, etc.   What ever happened to the spirit of 'be careful, but explore?'   Got the supply open.  I used a hacksaw to open each corner, then used a screwdriver to pry open the rest of each edge.  Opened right up.   Saw no obvious damage and no obvious broken wires, etc.  Yes, I was careful to stay away from the capacitor and the transformer. I know they can be dangerous.   I did not get electrocuted.  I was not able to fix the unit.  I did throw it in the trash.   Next time, if you can't give constructive advice please just don't respond.

Most of the AC adapters for laptops are switching power supplies, as you may now already. If you get the right equipment (testers, osciloscopes, soldering tools), you will manage to repair it. But in the end you will find that it is more expensive to repair it than to change it. The meaning of the word expensive extends, in this case, not only to money but to time and neurons ;)
