The power supply I ordered for my laptop was wrong in so many ways. Not only did the "universal" adapter come only with a car hookup; but, the plug for the laptop side doesn't fit in my HP/Compaq. Fortunately, desperation and creativity go hand-in-hand and I found a local power adapter I can borrow for a bit.
Of course, this stroke of good luck couldn't go unpunished. My laptop no longer charges its internal battery. My theory is it has fried it, like the last one fried.
This laptop is getting expensive. This is two batteries and two power supplies dead.
