Ok I've had several laptops over the years. A D600, a D420, and now a M1330 and and I've saved the power supplies from all of them and I found one more just lying around. Here's my question, I was looking at the PSU that came with my 1330 and it says that it has an output of 3.3 amps while the other PSU's have an output of 4.4 amps. The plugs are exactly the same. Will it damage my battery to run a 4.4 amp on a laptop that came with a 3.3 amp PSU. I don't see any power input recommendations on the battery itself either..

you are looking at the difference between a PA-10 and a PA-12.

I've been using the two interchangeably for years.

the only problem with the 3.3A charger is that they get hot as hell if you try to run

your computer on one while you have a dead battery being charged...

Wow, no longer lots of a tech i might say. First examine the DC power supply with the help of plugging into the wall and utilising a voltmeter to work out if the voltage that's stamped on transformer is definitely being output. it is probable no longer your situation in case you tried a diverse one. frequently what happens is this voltage would be stable, however the DC power jack on the motherboard is broken or lost connection. If the jack is loose and wiggles around surely, then it is probable the project. a speedy thank you to envision is to charge your battery in yet another pc and notice if the computing device works till the battery is going lifeless and pc shows no AC power even while linked to AC. if that's the DC jack, many computing device shops will replace the jack at a cost of around a hundred to 2 hundred money. the different issues different than this might often contain changing the motherboard.

You should be alright, as long as your not using a smaller voltage. However you might get a message saying that you are not using the recommended AC adapter.
