Pay least money, buy best Acer Aspire 5720Z AC Adapter

PRLog (Press Release) – Aug 31, 2009 – The Acer Aspire 5720Z AC Adapter voltage, current, and polarity ratings marked on portable equipment are there for a reason. Laptop ac adapter Voltage rating should not be exceeded, though using a slightly lower voltage Acer ac adapter will probably cause no harm though performance may suffer. The current rating of the adapter should be at least equal to the printed rating. The polarity, of course, must be correct.

laptop AC adapter that are not the switching type (1) and (2), can easily be tested with a VOM or DMM. The voltage you measure (AC or DC) will probably be 10-25% higher than the label specification. If you get no reading, wiggle, squeeze, squish, and otherwise abuse the cord both at the wall wart end and at the device end. You may be able to get it to make momentary contact and confirm that the Acer Aspire 5720Z AC Adapter itself is functioning.

The most common problem is one or both Acer ac adapter conductors breaking internally at one of the ends due to continuous bending and stretching. Manufacturers come up with all sorts of creative ways of making access a challenge:

Some are secured with screws - possibly with strange heads. If this is the case, disassembly is possible without damage, at least in principle. However, you may need to find or improvise Acer Aspire 5720Z AC Adapter for the special tool.

Some are fully potted and impossible to open without dynamite. Forget it, move on with your life. These will feel solid and there will be no 'give' when pressing the sides.

For those that are glued:

A hacksaw or thin file can be used to carefully cut along the glue line just deep enough so that the two Acer ac adapter halves can be popped apart. Make sure you don't rip into internal components! Gently whacking a large knife with a soft mallet may be a bit more persuasive.

A vise can be used to squeeze on diagonally opposing corners which will hopefully pop the case open along the glue line . After the repair, the two halves can be glued back together using something like Duco Cement or windshield sealer.

If this is a switching power supply type of Acer Aspire 5720Z AC Adapter, there are dangerous voltages present inside in addition to the actual line connections. Do not touch any parts of the internal circuitry when plugged in and make sure the large filter laptop ac adapter capacitor is discharged (test with a voltmeter) before touching or doing any work on the circuit board.
