My problem is with my toshiba power adaptor, which through movement of cable over time, caused the inner wires to become exposed outside of the moulded plastic housing of the plug. Shouldn't really happen, and managed to survive a little while by playing with the cable (moving it around), but it's sparking (shorting) now, and it's getting harder to simple move the cable and get power into the laptop.
Obviously, I will buy a suitable replacement part asap, but in the meantime, here is the scenario:
My AC Adapter (19V, 3.95A, 75W, 3-pin) Part No. PA3468E-1AC3 for Toshiba Laptop L40 18Z is now useless. I am currently risking using an IBM Thinkpad adaptor (my old laptop) after checking the spec. The centre pin polarity is the same, I cannot currently find any references to Wattage output for the IBM adaptor - but the only difference I can very is in ampage and voltage.
The defunct toshiba adapter is rated 19v and 3.95 amps.
The IBM adapter is rated 16v and 4.5 amps.
So far, I've used the IBM for several hours with no ill effect - risky I know! The lower voltage means that the battery isn't charging - but my concern is the higher ampage - 0.55 more. Could this damage the sensitive internal electrics in the longer term - or is it unlikely to make a difference. If it works, which it does - could I confidently continue to use this until I've sourced a proper replacement.
I'm after opinion here - I know that ultimately the risk is mine - but thought I'd throw it in and see what the concensus is.
