    When I explained to the guy what avatar I wanted, that wasn't what I meant!

    Have done that a few times Phill

    But now there are some Newer HP lappys around that if they don't have the right charger they won't let you do a factory restore

    Yes, the laptop will only draw what it needs.
    In hindsight I should have posted my Facebook status as: "I've blown the head gasket on my 1997 XR3i" rather than "I've just buggered a 14 year old escort".
    The police still haven't seen the funny side, my lap top's been confiscated and the wife has gone off to her mum's.

    As long as the PS has the current capacity that matches or exceeds the original PS...... no problem.

    PS... make sure the polarity of the connector matches too.

    Most are centre + but best to double-check.

    its only a 10.8 volt battery
    its a older compaq so the recover is long gone
    i read that as long as the ps amps are higher than the laptop is ok, correct?
    its running on a universal atm
    a original ps says 19v 4.74 amp

    The power supply you intend using should be of similar current capacity (amps/miliamps) and voltage as the original.
    The polarity of the connector should match that of the computer, as MTV has already stated.
    A 19 volt power supply should be O.K., although I do not know what you mean by a "power brick" (in your first post).

    Spot on Phil

    But fresh install doesn't worry about the PSU, like you said before

    That should be O.K., Phil. Get the polarity correct though.
