    Do you have to use the auto adapter from Sager or can any after market brand do the trick? if so any suggestions?

    I cant see why the computer cant run of any power supply giving a stable voltage (is it 19 or 20V?) given the condition that the power supply can feed enough power.

    however there is some issues to consider:

    EMF:
    some cheaper powersupplies can have a lot of noise and other EMF on the power wires , which could potentially be a problem for the computer. Either as unstable operation or simply noise in the audio etc.

    Operation:
    They could also have troubles maintaining a stable voltage during load changes(load regulation) ie light load = higher voltage, heavy load = lower voltage, typically a few volts change. Or fluctuations in the mains could give voltage fluctuations on the output(voltage regulation)

    Variants:
    All common problems with different type of supplies, not necessarily so but something to be aware of. It is impossible to say if it will be the case for you as there are a gaziilion number of power supplies.

    Reliability:
    Cheaper supplies are often designed with less marginal (for example, less sturdy switching transistors to shave of a few cent here and there, or cheaper capacitors with less temperature tolerance) which can affect reliability of the supply, especially under worst case conditions (high load and high ambient temperature)

    Summary:

    So of course, to be certain of good operation , get the brand one. You would probably not save so much anyhow. Generally, when it comes to powersupplies, you get what you pay for.
