I have a gateway and it's the old version. My original charger broke so I bought a new one on eBay. Horrible mistake. I think it might have made shot cicuit because smoke cane out where you plug the cgharger in the laptop. I unplugged it as fast as I could. I was really scared my battery might of fried but the next day I turned it on without using the charger and it worked just fine! A bit later it died thought because I could no longer charge it. So I decided to get a universal charger rather than buy a cheap one and have the same thing happen again. When I plug it into my laptop it doesn't want to charge. I thought my charger didn't work, but I tried it on a friends laptop and it works fine. My question is.. Did my battery die when the incident happen? Even though it worked fine the day after? Why won't it charge??4 AnswersLaptops & Notebooks1 decade ago
My laptop doesn't turn on anymore since one time I bought a charger on ebay that over heated the laptop because smoke came out and it smelled horrible. The next day however I turned on the laptop without plugging the charger in. It was running on the last power it had and it turned on and worked fine. It died later on cause the power ran out and I bought a universal charger and it doesn't charger on my laptop but it charges on others. So if it worked after the incident but now it doesn't want to is my battery dead?2 AnswersLaptops & Notebooks1 decade ago
My laptop gave up on me. I bought a new charger for it and I know it doesn't have battery problems but it won't turn on anymore at all and all my memories are in that laptop. I want to buy a new computer. A desktop to be specific but I want the memory that is in my laptop because I can't turn on the computer to take pictures or videos out. So my question is. Would I be able to remove the memory from my laptop and place it in a new computer or something similar where I can have my pictures and videos back not turning the laptop on because it doesn't work. I of course would let a tech change the memory. I want to know if it's possible though before I go waste money. Thanks in advance for all the help. I've been feeling extremly down lately because those memories mean so much to me.1 AnswerLaptops & Notebooks1 decade ago
