Laptop PSU only giving out 13v,should be 19v

McGraw · 01-03-2007, 09:45

Is there anything I can do to bring it back to life?

Cheers.

How did you measure the voltage?. If it is correct there's not much you can do, laptop PSU's don't have any user serviceable parts (unless you're happy playing with mains voltages it's best to leave it alone).

Maplins sell a replacement unit (on offer at the moment)

very unlikely,
it will be a switched mode psu, so one big feedback loop, very difficult to fault find on, even more so with out a circuit diagram.

Have to bite the bullet and source a new one, prices vary widely - google will be your friend here

Thanks a lot.

The missus is off sick at the moment and the only thing she wants to do is lie in bed and MSN people.

Unfortunately, her PSU died last night.

There is a PC World right near her but they are ÃƒÆ’Ã¢â‚¬Å¡Ãƒâ€šÃ‚Â£70 in there.

Microdirect do them for ÃƒÆ’Ã¢â‚¬Å¡Ãƒâ€šÃ‚Â£20 Plus VAT so I said I would bring her one home.

Sorry, it was measured by PC World.

That fills me with trust

I wonder how they checked it, off load or on load? In any event it's cheaper to buy a replacement than repair the faulty one, that's the way it is these days.

what make lappy is it mate, if it is Dell then I have a spare one you can have for ÃƒÆ’Ã¢â‚¬Å¡Ãƒâ€šÃ‚Â£20

does the power supply charge the battery? and if it does does the laptop work ok when its plugged in? if you answer yes to both these questions why worry?

McGraw · 01-03-2007, 15:03

No idea how they tested it, sorry.

It was a lite-on for Toshiba. I'll be replacing it with a trust one for about ÃƒÆ’Ã¢â‚¬Å¡Ãƒâ€šÃ‚Â£20.

It doesn't charge the battery at all.

Maplin sell them at not unreasonable prices if you havent already got one.

Just a word of caution if the P/Supply was checked on load ie connected to your lappy then there is a possibility that there is a fault with your laptop that is pulling the voltage down.

If the batterie is inserted then take it out and try your p/supply without it.

Agreed, the charging circuit in the laptop could be faulty, or even battery at end of it's life.

As banjo said, try using it with the battery out, works on Compaq laptops, not sure about Tosh
