*VGN-FW series Voltage issues

Hey guys, just to let you know that I've noticed that the vaio charger for these series: VGP-AC19V that are not in the recall in fact have voltage ripple. For those of you who don't know what that is, it is ac voltage that isn't filtered which may cause harm to your laptop / motherboard. You may test this for yourself, take a voltmeter preferably a digital one, connect one end into your house ground, and the other end onto the outside (negative) part of the laptop charger. Set your voltmeter to AC and watch as 50-60 Volts AC come out of the negative part of the charger. I have video's of this and tested it across multiple chargers. I contacted Sony, they sent me a new charger with the same issue. I got mad about the quality of the laptop then I purchased a filtered charger from ebay and sold my laptop afterwards because I was upset about the quality of the sony products and because of how sony treats their customers as if they were stupid. Anyone can take a measurement using a voltmeter. I got even an electrical engineer to look into it he told me its caused by bad filter/ capacitor and that he could fix it for me. Let me know what the rest of you guys are experiencing.

Many other models may also be affected by this.

Also as a side note I didn't like the fact that the FW series had the laptop mouse pad buttons integrated on the motherboard. They fail very fast and I would definitely not buy a new motherboard to fix a little switch. Also I think all these companies should be more like dell in providing their customers with service manual's. It helps out when taking apart a laptop and shows that the company actually wants to help the community. Personally I will support companies that do this from now on.

 

There are other factors to take into account. For example, the electrical grid that you connected your adapter to may be rampant with noise, hence causing the amplified fluctuations in readings.

I can account for bad rippling when I'm at college. This can be noted by my brick making rather audible fizzing sounds. Which is understandable considering there are many people and power points in use in close proximity. However, when I'm at home the fizzing sounds (hence the ripples) are not there.

Though in both cases, my adapter gets borderline hot (greater than warm) when the laptop is used excessively. Which IS, no doubt, because of the capacitor(s) not being of a high standard. Either that or the PCB design inside the brick is rather bad (though I can't comment on that as I've never taken the brick apart before).

 

I did take the readings of my house to guarantee that the ground is in fact 0v. It did show up as 0v when I tested the potential difference between ground and neutral and showed up as 120 v from ground to hot and neutral to hot. I tested hp chargers, gateway chargers, etc to find them all under 2 v... this lead me to the conclusion that the sony charger has a major problem.. 60v is a lot
