Two things you DO NOT USE AFTERMARKET for. Printer ink and power supplies.
Save a few bucks on an aftermarket power supply and it breaks. Who do you call? It over surges and kills your battery or worse, the charging circuit in the laptop and fries the motherboard. Is that worth saving a few bucks? Not for me. Get an Acer power supply.
I have an Acer Aspire 5612 WMLi laptop. The power adapter is acting up (i.e. plug it in and after about 5 seconds the green light goes out and the computer switches to the battery). I am looking into a replacement adapter. My local computer store sells Dr. Battery adapters. Their website says that the replacement for my laptop is a 19V/3.42A unit but my adapter says it is 19V/4.74A.
Should I get this adapter or try and find a 4.74A unit? I am not very familiar with power requirements and what they mean.
Thanks in advance.
