My AC adapter i normally use for my laptop short circuited. (AC adapter made clicking noises then stopped working)

 

When I looked around in my garage to see if I had a replacement adapter, I found an AC adapter that had a head that fit into my laptop, but had less output voltage then the one that had been using.

 

Is it safe to use this AC adapter I found until the new one I ordered arrives?

 

The AC adapter that normally use has specs of:
Input: 100-240V - 1.5A 50/60HZ

Output: 19v-3.42A

 

The AC adapter I found has specs of:

Input: 100-240V -1.2A-0.5A 50/60HZ

Output 16v-3.36A

 

When I use this AC adapter I found, the battery level is stuck at 32% with 10hr 01min remaining.

 

I read somewhere that if the laptop tries to draw more power from an adapter then it is normally capable of, the adapter will short circuit, would it be safer if I used "power saver mode" for power options instead of "high performace" that I normally use?

 

Should I take out the battery???

2nd Question. I have a AC adapter, of the same laptop, that I had to replace with the new one because it's head broke off. Would it be possible to attach the head of the Adapter that short circuited to the adapter that's head broke off? Would it work?

Hi

 

The answer to both questions is NO.

 

Buuuuut, my unofficial answer that I take no responsibility for in the event that it causes damage (it might) is...

 

The old one is 64.98W (19*3.42) and the one you found in the garage has less wattage, 53.76W so it probably wont hurt anything.

I would only plug it in to charge the battery and then run it off of the battery instead of running it plugged into the AC adapter.

 

On the second question, what exactly do you mean by the 'head'? If you mean the plug that plugs into the labtop's power jack then I need to know what kind it is since some have 2 wires but others have more than two and can be difficult to work out which wires go together without some careful preparation.

 

James
