Help with power cord for Sony Vaio

Hi, I am looking for some help here..!?

I had Sony Vaio FZ 140 (with VGP-AC19V19 power cord). Recently, i got another Vaio VPCEB36GM (with VGP-AC19V48 power cord). My question is, can i use the older power cord on the new computer..??

Older cord: output 19.5v, 3.9A
New cord: output 19.5v, 3.3 A

Will it make a difference..(of 0.6 A output)..?
Thanks

 

Unless you were already pulling power close to the limit of the old adapter... I doubt the difference will matter.

 

As long as the output is greater, you should have no problem as the notebook will only draw as much as it needs.

The question though: is the plug actually able to fit into the new notebook? And, is the polarity the same for the two plugs (even if they are the same size)?

Good luck and be careful!

 

Most Sony use a 2 prong power cord. It shouldn't make a difference. If you feel that bad go buy another power cord off Ebay, it's like under 10 bucks.

 

dravp may be saying 'cord', but by supplying the voltage and amperage specs it is pretty clear to me he is talking about the power brick.

 

Well that being said:

The wattage of the power bricks are totally different;

Watts = amps x volts

Old: 19.5 volt x 3.9 amps = ~76 watts
New: 19.5 volt x 3.3 amps = ~64 watts

The older adapter was probably powering a notebook with discreet graphics as the wattage is more. The new adapter is slightly lower, which could be a cause of concern as you can burn out an AC adapter like that

 

No,

as I posted originally; the notebook will draw as much current as it needs.

A higher powered 'brick', but at the same voltage is much preferred over a power brick that could start to malfunction when its specs are reached or exceeded.

 

The maximum wattage (supposedly) for the newer one is less than the older one. The problem is if the laptop draws over what the new one is rated, it will burn out the new one. Now 10 watt may not make a difference, but some of the Dells have 90 watt for notebooks with discreet graphics vs 65 watt for integrated GPUs.

 

Okay, you're not paying attention:

Wattage is not the important metric here.

Voltage is.

The voltage between the two is the same.

The new brick only needs to supply 3.3 Amps. While the older one can supply up to 3.9 Amps at the same voltage.

As long as the plugs fit and are the correct polarity, the older brick is just as capable of providing proper power as the new brick.

The notebook won't draw 3.9 Amps just because the power supply allows it: otherwise all 120V AC products would be using 15/20 Amps - Always - which just isn't so.

 

Hey thank you guys for the responses. I had checked earlier, and the pin fits perfectly and the polarity is also the same. Thanks again

 

Very logical... did not think about it before..!!
