Power difference between 15 and 17 inch laptops?

My wife just obtained a new 17 inch HP, and previously we've had 13 and 15 inch HP laptops. The 17 inch one has a different plug for the power adapter. I was wondering, does this mean it has different power requirements, so HP doesn't want to use the brick used for previous models? Or are they just gouging us by not letting us use the old bricks?

2	The larger display might use more energy, also depending how powerful the machine is that might cause it also because the more powerful normally the larger the power brick. answered Mar 07 '11 at 17:06 TheTechDude 16.8k●40●94●298

How old are the older systems?

I know that in laptops, OEM's will sometimes change the power adapter for one of several resons.

I have used and HP G61, (15") G62 (15") and G71/2 (17") and they all have the same adapters, as does the HP Probook.

However, HP might have changed the adapter sometime in-between the release of your laptops, maybe they had issues with the other.

It will be likely that 17" uses more power, as it has more to power. A larger screen uses a little extra, and no doubt it has a little more kick to power, but in most cases, that's not a reason to change the plug, only the power brick, which converts the current.

In other words, the tip might have changed for any number of reasons, but shouldn't have changed based on power requirement.

Only the size and spec of the brick itself will
