I have an old IBM laptop and i couldnt charge that, The power supply is working but when its connected to the laptop it doesnt work and doesnt want to recharged the laptop, what should i do then?
Unfortunately it sounds like your power supply may have reached the end of its days. If it appears to be working until you connect it to your laptop it means it isn't strong enough to feed your laptop anymore so to speak. Try taking your laptop to a computer shop and see if it is indeed the power supply that is faulty. That would be the best case scenario. Otherwise you're looking at an internal problem which would be much harder to remedy as it is an old laptop.
