What is a good universal AC/DC adapter for laptops, and how do I use it without frying the motherboard?

Maybe I read the question funny, but if the adaptor is chirping, its dead. If the chirping is coming from the laptop find a friend with a cheap multimeter and test the AC adaptor.DO NOT buy a new adaptor until you test the old one if the laptop is chirping, unless you like to gamble and don't mind wasting money. I don't know of any other ways to charge a laptop battery easily.

Sure, you could make something, but its not worth it as adaptors are cheap.. However, if the ac adaptor is chirping, I like the TARGUS BRAND for a good solid Universal brand.Cheap.Easy. And includes a bunch of extra tips for other computers. Make sure they have Sony Tips.

I didn't have a tip for my Vaio and had to find a Vaio adaptor recently.. Kensington is also a nice Universal brand. Universal would be a nice purchase if you have more than one laptop... As for buying an adapter off ebay, honestly, they are all the same thing. They are probably made in the same place as OEM adapters, but just generic.

Nothing wrong with the generic, probably made in the same place. Most ac adapters are made in China, in a handful of factories. Voltage is voltage.

MaH is MaH (milliamps) . Same thing. Your computer won't be able to tell the difference.

Just make sure the tip is the same as well. Voltage, MaH and Tip must all match for it to work.. However, If you can find an OEM ac adapter (SONY branded) for $5-10 more, buy it. If not, its not worth the extra money just to feel good.

Having an OEM adapter will also add to resale value though not much.

The ac adapter that comes with that model laptop originally is part number VGP-AC19V19 and if you search that on google, eBay etc... you will find plenty of information and people selling it. Let me know if you need help with anything else. Good luck.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
