I have an Acer laptop which gets a lot of use. The problem is the charger. Due to wear and tear the cable has split (see photo). I could easily get a replacement power supply, but I'm wondering if there are power supplies where the mains power cable and the cable to the computer are both detachable. A search on the net revealed that there are some power supplies with this feature for ASUS computers - e.g. ASUS N90W-03 ADAPTER. So far no luck for the Acer. The output the Acer power supply is 19V and 4.74A. A generic power supply could would be ok as long as it met my wattage and cable requirements.
