Do you repair leads?
I have many laptop PSUs with damaged low Voltage plugs/leads. Since new PSUs cost anything from £20 - £70, I offered to fit new plugs @ £2. Our new school manager thought this was not a good idea from a legal liability poit of view.
In the past I did all sorts of repairs and wiring. I've stopped mains wiring now, because by the time you've paid to have it certified, you might as well let a contractor do it and self-certify. But I had continued to do anything at Extra Low Voltage.
I just wondered, what happens elsewhere?
Replace the whole brick here, as no-one has the skills or qualifications to fit the leads.
Its not worth the risk for the cost of a new PSU to fix internally.
Too many "where theres blame theres a claim" companies out there.
