Having problems with your Acer Aspire 1662WLMi Notebook ?
Laptop runs hot and freezes - heat damage or Power supply issue?
\015 I've had my computer for about three years. One reoccurring problem with it has been the battery runs down from 100 to 0 in a matter of minutes and the connection in the back of the computer is so loose that if it's sitting on my lap or even a table, it can go into and out of connection, back into connection and out of connection again several times in a matter of seconds.\015\012\015\012Anyway, the other day I was running the Hellgate demo and occasionally leaving it on a leather Ottoman (I know, stupid) for a quarter hour at a time.\015\012\015\012After I quit playing, I was just doing some casual surfing when suddenly the computer went completely down.\015\012\015\012Reboot suggested a file was corrupted (I've forgotten which one). I System Restored and everything seemed to be fine. I continued my surfing for a couple of minutes, then the computer froze solid.\015\012\015\012I had to unplug the computer and detach the battery to get it to shut off.\015\012\015\012Got the 1-3-4-3 beep on reboot attempt. I let it cool down.\015\012\015\012Reboot seemed normal, but after several minutes it froze again. Didn't shut down, didn't crash, just froze solid.\015\012\015\012It's always run very hot, so I let it cool and did some research. Eventually I pulled the heat sink, cleaned it and the CPU and Artic Silver 5'd it pretty again (it was pretty dry / "blotchy" looking). Didn't help at all. I was getting blank screens and the 1-3-4-3 beep routine on Power Up.\015\012\015\012So I figured out what the 1-3-4-3 beep meant and re-seated the RAM card. Computer loaded up beautifully but after fifteen minutes or so it froze again. Thankfully I got all my necessary stuff off the computer (thank goodness for flash drives!).\015\012\015\012I noticed that the RAM (1 GB - replacement) card seemed hot. Oh, one of the two RAM docks is apparently non-functional. It went out several months ago, at least.\015\012\015\012I'd rebooted when I realized that I could actually CAUSE the computer to freeze by removing the battery and sometimes even the power cord during operation.\015\012\015\012I tried another battery from my wife's computer (duplicate computer purchased at the same time, but her's actually holds a charge), and the computer froze just as it would with mine...though now that I think about it I didn't try just running the computer off of her battery.\015\012\015\012I pulled the 1 GB card and tried a 256 RAM card from her computer and again, the computer froze normally.\015\012\015\012A friend suggested it might be a power supply problem created due to a Hellgate memory leak having drawn too much power to RAM during my play of the demo and screwing up the way the computer regulates how much power it takes in. He thinks I should take it to a hole-in-the-wall shop near my work and ask them to check the Power Supply.\015\012\015\012Anybody have any suggestions on anything else I should try beforehand?\015
As for the battery over time batteries hold less and less of a charge until you have next to know battery life. I had similar heating problems with a macbook and it turned out my fans weren't running at all so that could be the cause or it could be a bad heat sink. Some laptops just always run hot because of poor ventilation design. IF your acer computer is still under warranty(usually if it is a year old or less) I'd call them and have them check it out for you. I know one of the best solutions I ever found for a laptop that always runs extremely hot was a metal plate of metal designed to absorb heat. I'd just put the plate in the freezer for 10 or twenty minutes or until it got really cold and put it under my computer and that kept my laptop running cool for hours. If your having ram issues and it's a hardware problem there isn't likely much you can do.
Check the heat sink..if its not properly insatlled the somputer reaches the warning temp and shuts down the processor to prevent damage..you may have to replace it if its damaged..heatsinks dont cost much..

Lockup My computer works great except, it frequently freezes and will not take any input from the mouse or keyboard. It generally does it while you aren't using any input. Loading of a page or navigation on line. There is no pattern to it and it's even froze a couple times on the screen saver. I can seldom go for more than a couple hours without this occurring, sometimes only a couple minutes. The only cure is a reboot. I'm pretty sure it's a hardware problem.
