Would a generation one Dell XPS Power block work on the M15X??

I just received my new M15x to replace the Dell XPS (generation one) laptop that I have owned for the last 4 years. I noticed that the output on both of the power blocks is 19.5 volts 7.7a. The power block from the original Dell is much larger and I was wondering if it would have more backup power than the newer smaller one supplied with the M15x. I have read in the forum some people speculating that the power block my be the cause of some of the throttling that could happen. I have not seen this throttling nor do I expect to have it happen anytime soon. But was just curious what others thought about the power block swap.

 

pretty sure the physical plug is different. But if the voltage and current are the same it SHOULD work - no guarantee. That being said, will most likely void your warrant if dell finds out

 

Checked out the plug ends and they are identical. The Alienware one lights up at the top of the plug but that is the only difference. I don't plan on switching them but thought that the older for the Dell XPS might work to solve the power problem some people think they are experiencing. It had to power a desktop pentium 4 3400 processor which I imagine used more power than the new I7.

 

You would probably be wrong on the power usage. And like I said, make sure the currents and voltages match

Anything you do is at your own risk

 

it should work no problem

but i can't guarantee but i personally would try it

 

Well, as said make sure the voltage is the same and the amount of current is equal or more. If it is the same there is no point in doing it. Also, make sure the POLARITY is also the same. It should be, but its better to be safe than sorry.

 

Why are you trying this again? Just to have a 2nd adapter?

 

No I don't plan on trying it or doing the switch. But I have read about a throttling issue with the M15x in some Benchmarks and it had been speculated that it was possibly the power supply. When I noticed that the outputs were the same from my new M15x and my old Dell XPs it made me wonder if here was a possible solution for someone concerned with the throttling issue. The power block from the XPS is about 2 1/2 sizes larger....thus I wondered if it may have a larger wattage output in total. This is the area where some were thinking that the new power block had too low of a wattage total output for max power situations. I am by no means going to jeopardize my new system by switching power blocks. The old XPS still performs nicely even after 4 years and will be now be used as a work computer used on various civil projects that we work on. It's always nice to have that mobile computer out of the office and all of you plans are in digital format on it.
