I have a Dell Inspiron 6000 that's a few years old. Recently I replaced the battery because the original one stopped holding charge. I bought an affordable 11.1 Volt, 7000 mAh, Li-Ion Battery on Amazon. Soon thereafter, my AC adapter started to melt. Thinking the problem was the adapter, I bought a new one (Replacement AC Adapter + Power Supply Cord for PA-12 / Dell Laptops Replaces DELL Model and P/N Model PA-1650-05D / P/N 5U092 310-2860 1X917 ). The new one also gets extremely hot if it's plugged in for more than a half hour. This is annoying because I have to charge the computer for a few minutes at a time, unplug it, then charge again. It seems like the problem could be the battery (a bad battery can make the AC adapter burn, right?), but the computer/battery doesn't get very warm at all. Any suggestions?
