Thanks all for your contributions. Our Ac source is rated at 220V. The
power pack heated up when the laptop was on. I will try to find a power
pack with a higher amperage rating - the voltage input is standard 19V.
Would it be a wise to become a little bit ambitious and try to replace
the output semiconductor devices say with ones with a higher power
rating assuming they are only defective components?
Thanks.
