    Where to buy a good laptop power adapater?

    For a HP G6000, my original broke as the wire snapped in half. I bought a replacement off ebay, but it gets so hot I can't even touch it. It's melted away the glue that held the sticker to it, and last night burnt a receipt, so it's a bit dangerous to be using.

    sounds like the laptop is trying ti draw more power than the adaptor was designed for. if you take a look at what the new adaptor is rated for and add say 500ma to it, then find something with that rating it shouldn't get so hot.

    Hmm, alright. I'm sure I tried to match the new charger with the old one, i'll have another look now. Thanks for the advice.

    Just had a look:
    Old Charger:
    Wide Range Input: 65W
    Input: 100-240V 1.5A 50-60Hz
    Output: 18.5V 3.5A

    New Charger (Hot one)
    Input: 110-240V 1.7A 50-60Hz
    Output: 18.5V 3.5A 65W

    Guess they don't match up so well after all.

    I have just had to but another charger for my HP laptop it only lasted six months but I don't think they are covered by a guarantee from HP. I went to a local store because there are so many different chargers that could fit it.

    You could also putyour computer make/model in the HP site and then it will tell you which charger you need.

    hmm from those numbers it ought to be ok, the only difference i can see is that the new one appears to be less efficient.

    Yeah, I did try and match them up when I bought the new one. Thing is, the new one is from ebay, the guy could have slapped any old sticker on it.

    Why not just repair the original one? If its just a broken wire its nothing that 5 minutes with a soldering iron and some insulation tape and heatshrink couldn't fix!

    Less efficient would mean more heat, so it sort of makes sense. When you (the OP) say it 'burnt' a receipt, are you talking about making a thermal-ink receipt turn black (because that doesn't actually need that much heat - certainly a long way from setting something on fire!).

    I didn't think it'd be safe to repair the old one, but if it is i'll do that, I just hate getting the hard plastic off to get at the wires.

    And yes, that must have been what happened to the receipt :whistling: But still, the power block does get really hot. Best place to get heatshrink?

    I reckon its probably okay you know, although obviously you know better than me how hot its actually getting - but its perfectly normal for a power brick to get pretty warm when in use. Did\does the sticker have relevant safety labels on it (CE, GS, TUV etc) and a brand-name?

    It does have the safety labels, but no brand name. There's a slight buzzing from it aswell, is this normal or could it be damaged?

    I think i'll fix my old one anyway, good to have a spare. When buying heatshrink, is the size stated what it will be once it's shrunk, or before it's shrunk?

    the buzzing is normal it's caused by the adaptor rapidly switching the circuit on and off which is how it produces the step down.

    Got mine from amazon - came next day - genuine hp 14.49 + 3.95p&p.

    Both figures would normally be given but if just one is it will be before its shrunk - it usually shrinks to upto nearly half that diameter - its also good to find a low temperature one (under 100 degrees) otherwise its hard to shrink with a hairdryer :thumbsup:
