Does anyone have a Lenovo AC adapter 135W 20V 6.75A?

    Recently, I bought a refurbished ThinkPad W541 and I have a problem charging it.
    It only charges when it's turned off or in sleep mode. When I try to boot it with charger connected, it gives a BIOS message saying AC adapter has low wattage. I get a similar message in Windows.
    Checked the adapter and it has 65W only, but looking online the laptop needs 135W. So, the warning message seems accurate.
    Before I ask the seller about this, I wanted to check if it's actually the adapter, because I found on some forums, that it might also be a motherboard problem.
    So, does anyone have this kind of adapter or know where I could try one?
    Thanks.

    The term "refurbished" lets me think you bought this from a store or seller who does this as a job; They can't call it "refurbished" if the laptop's missing its original PSU and you're provided with the wrong unit for the computer. The W541 is more a "portable workstation" than an actual laptop, and it did indeed come with a 135W PSU:

    No surprise the poor thing is complaining.

    So long story short - if it's supposed to be "refurbished" contact the seller and get the correct unit.

    Yeah, talked to the seller and was told that dispatching team sent the wrong charger.
    They sent me a new one.
    Hope that's the only problem. :P
