Run your finger over the label - sometimes a screw is there. If you do detect a screw, you will probably ruin the label trying to peel it off. More likely, this assembly is cemented together. Take a sharp knife and slowly work the blade into each corner of the seam, prying just hard enough to break/pop the seal. If you are not careful working with a sharp instrument in your hands, well, I can post my own photos of the results. (Actually, I think the assembly is ultrasonically welded together. Not really cemented, but the effect is similar).
And what will you do when you open it? (considering that you already have troubles opening it in first place?) sebus
Well, its the adapter of an old wifi router/modem. The adapter is not working.. so I would like to try & fix it if I can. PS: I checked the wifi router/modem with my friends adapter.. it works fine
If it's already dead you can't harm further . Afaik they use mostly glue so it needs some defined force (no brute mode) to opem them. Better check for any screws first. I pimped several of those by soldering a cable with a stable plug. External adapters tend to cover their neighbors when plugged in and mostly don't fit exactly. BTW: Samsung solved that challenge in a very clever/simple way, since it is a box with two cables ending in the powerplugs for monitor and power distributor ... well done Gentlemen . 2nd advantage is, there's no heat source that can fry capacitators .
Spoiler I have found 2 adapters after digging out and searching for 2 days. Both are old..very 1. 1 of them is of a 16bit video game.. It was broken so it has green insulation tape on it 2. another 1 is white Panasonic multi AC adapter, adjustable, 1.5v to 12v , & + / - polarity Tried them both and both turned out to be hopeless Posting pics of them soon..
doubt it.. 12 volts is 12 volts.. the amps are just needed to deliver the strength, it can kill the charger, mb.. but so long as there is 12 volts it should do the trick. until the voltage drops from sheer exhaustion, it should at least start the whole router while it still can.. especially as we know that the router works okay. mb look into some phone shops, taking router with you. those guys have got lots of useless chargers, mb you can get one cheap. there is even a 12volts with ample power [amps] in old pcs, come to think of it, to give a stable 12 volts to the antique processor, come to think of it.. that would be the yellow plug. not in modern atc power units. just nothing much to lose. mb worth a try.. just my 2 cents.
Found the adapter of the speaker's (creative inspire 4500) of my own PC from which I'm typing this right now.. It's 12v 2.9A .. will check it out right now..
with pleasure! nowadays it is overeasy.. i just walk into shop and i get what i want. but have not forgotten the frustration when things did not work, and i had no money to get things to work.. so it is very gratifying for me to hear that the old router started to behave again, my friend. my compliments!
