It seems the pin is more based on the current. this laptop, I can plug its adapter into a smaller and older laptop, but the for it will not plug into this one because of the pin diameter.
plugs will not go into something with the "wrong" voltage requirement.
The older ones seem to standardize on one thing and it's up to you to
hit the right voltage.
I design all my stuff with polarity protection, and the voltage
limiting/protection is starting to be a design feature, too.
Now ask what happens if the MOTHERBOARD won't recognize a valid powerI'm going to conclude that there's an evolving standard out there, andTypical corporate behavior. Captive market is king. If they continue this and sell enough of them like that then a market will be created for aftermarket chargers. It is not all that difficult. Just a matter of a custom tailored current output and their batteries are not of any brand new technology that doesn't exist yet.
Now ask if I buy any more DELL computers.
Not a connection on the battery. Didn't look and didn't at that timeThose adaptors (and don't ask me what I think of them) work with aThat's why we have test equipment. Take all OEM parts and let them work together a couple of times, Measure everything. Would I do a one off for myself ? No, I would get rid of the thing. I almost didn't buy these Gateways but the price was right. Large screen, full keyboard and 2 HD bays. But though there are multiple connection on the batteries (I have 3 I think) but the adapter only has 2, so there is none of that captive market shit.
care. Power brick and laptop.
