    Sister's Laptop: Strange Behavior


    I am the computer guy for my family and for my household. But I have ran into a problem that I cannot solve. It's with my sister's Acer Aspire 5749z laptop. The computer originally came with Windows 7 Home Premium 64-bit but was later upgraded to Windows 10 Home 64-bit. From the beginning or from what seems to be the beginning, she has had problems with what sounds like the fan kicking in really loudly. When I turn it on sometimes, not sure what I am doing at the time, but the speakers crackle. Also, now when she closes the lid for it to go into hibernation mode, the computer has gotten to where it's whistling or making a screeching sound. The computer is old. It was purchased in 2012. I never close the lid on my Laptops, so I have never experienced this problem. But I don't know if it's a problem with her model or not. But again, the fan has always kicked in and made it sound really loud. I looked online and it said that usually when the computer whistles or screeches, then the CPU may be facing a high temperature issue or a lack of ventilation to the hardware components. She also says that the mouse touchpad has been acting up. It had a driver update for the touchpad recently, so I am thinking that the driver may need to be rolled back to the previous version.

    There is one thing that I have always told my sister to never do to a computer (Laptop). That is to never put a Laptop on a bed, because I feel that will block off the ventilation for the vent to let air out although she doesn't always listen. I have always kept my Laptops on a table or a desk.

    I am trying to help her. But I would like someone's opinion on the forums because I trust y'all because y'all have always helped me.

    Thanks!

    The best thing to do is take off the bottom cover and blow out the fan and CPU. The only reason that the fan would kick in is either something locking up the CPU to 100% or full of dust and hair on the heat sink and fan. As for the speakers, yes speakers can go bad, they are not the best on laptops, but you can get the replacement units that go above the keyboard on that side if that is where they are and get the sound back to decent. Usually if speakers are crackly, they are blown or the unit was left in a hot environment and dried them out.

    The laptop is seven years old. It is worth her just upgrading to a new one to replace that one. I would suggest that she gets one with either a M2 or SSD drive. If she hates 10, which some do, she can always go through HSN and pay payments on a Macbook Air. Her choice and not really worth dealing with what it will cost over keeping her laptop limping as other items go bad on it.

    I will let her know. It's been a good one.

    Not sure if she needs a new fan or just cleaned out, If your not comfortable taking apart a laptop you should take it to a computer store.

    I use a kitchen chopping board under my laptop it works great.
