Laptop Power Adapter

by anabranch May 6, 2009 7:44AM PDT

Hi,

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.

Charlie.

Take my advice . . .

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.

Get from Acer Service Centre

Well, ring them up to check which retail sells the part you're looking for.

Not sure whether company like Targus which sells adapter for various laptop model will be suitable. Given the 19V/4.74A being the original and 19V/3.42A to me looks like it's an underpowered adapter, which is go charge up your battery way slow and won't likely be something I will use to charge up an old battery.

for the Acer laptop,you can check the bottom of the laptop ,for some model you can find there is 3.42/4.74 these number,it means you can use 3.42A adapter or 4.74A adapter for the same laptop.

Cheers
