I have an Acer Aspire S7 and the DC power socket is goosed so I looked up t he part on ebay and it is only £4.50. However, the youtube video on fi tting it lasted 50 minutes so I took it to a repair man who said the job wo uld take HIM about 1.5 hours.
What a palaver for such a simple part - still he'll only charge me £20 .
