I have an old acer laptop TravelMate 5520. Bought in 2008. Running Windows XP. I really liked it. First it started to overheat. Soon after when I click the power button, the CPU fan starts for a few seconds and then the laptop powers off. I wanted to ask what could be the cause of this defect and is it worth repairing the laptop?

    You can try a new battery and replace the 2 x DDR2 RAM modules if you can still find these, but there may be bad contacts too. IMO not worth the repair costs.

    I wouldn't be terribly tempted to spend any money in trying to figure it out. At close to 20 years old it's not going to end up being anything very useful. If you do want to dive into diagnosis though we can look a little at what actually happens when a laptop is first turned on.

    When you hit the power button, the motherboard tells either the battery or the AC input to provide power to the rest of the motherboard. That often can be seen by the CPU fan turning on, as well as some status LEDs. When that power is applied to the motherboard it powers up the CPU and memory. When the CPU initializes it then tests the first small portion of memory and copies the contents of the BIOS into that memory and does a couple of housekeeping tasks, such as turning the fan back off or setting it to a slow speed.. All that happens before the first code is actually executed, it's instead built into the CPU and chipset. Once the BIOS code is copied to memory the first actual code execution happens and POST (Power On Self Test) is started. The first thing that POST does is initialize the rest of memory and run a quick test on it to verify things are working as expected. If that test fails, you typically get a continuous beep sound.

    On your system it sounds as if the CPU is initializing, which turns the fan off, but POST isn't getting started. That could be a corrupted BIOS or a failure to load the BIOS code to that first portion of memory, or an issue with the first portion of memory not being able to initialize. I'd guess the former more often than the latter. Try replacing the CMOS battery, if you haven't already, they will typically last for 7 years or so, and you could be ready for your second or third one at this point. Then do a CMOS reset. There is likely either a reset header and jumper on the motherboard, or a pair of reset pads. You can sometimes also do a reset by shorting the leads of the CMOS battery for a minute or so with the battery removed. Once it's been reset, put it back together and try again to turn it on.

    Thanks for this "dive" into diagnosis. Very informative. I'm using a new laptop for my work. I'll check the old one when I have a little bit of free time. Best regards

    You can try disconnecting the battery and hold the power button to reset the internal power.

    Please remember to include @AnhEZ28 when you want to reply back to my comment so that I can check your response.
    Thank you and have a nice day!

    The Acer TravelMate 5520 experiencing overheating and automatic shutdown could be worth repairing if the issue stems from a clogged fan or dried thermal paste, which are relatively inexpensive fixes. However, if the problem is a faulty motherboard or CPU, the cost of repair might outweigh the value of the laptop, making replacement a more practical option.

    Factors to consider:
    Cause of overheating:
    Dust and debris: A common cause is dust buildup blocking the vents and fan, preventing proper cooling.
    Dried thermal paste: The thermal paste between the CPU and heat sink can dry out over time, hindering heat transfer.
    Failing fan: The fan itself might be malfunctioning and not spinning properly or at all.
    Faulty motherboard or CPU: In some cases, the issue could be more serious, involving a failing motherboard or CPU.
    Cost of repair:
    Cleaning the fan and vents is a relatively inexpensive fix.
    Replacing thermal paste is also a low-cost repair.
    Replacing the fan can be moderately expensive, depending on the availability of parts.
    Repairing or replacing the motherboard or CPU can be very expensive.

    Age and condition of the laptop:
    The TravelMate 5520 is an older model, and the cost of repair might be more than the current market value of the laptop.
    Your technical skills: If you're comfortable opening up the laptop and cleaning the fan or replacing the thermal paste, you can potentially save on repair costs.
    If you're not comfortable with disassembling and reassembling the laptop, you'll need to factor in the cost of professional repair.

    Your needs:
    If the laptop is still functional for your current needs after cleaning and replacing the thermal paste, it might be worth keeping.
    If you need a more powerful laptop for demanding tasks, replacing the TravelMate 5520 with a newer model might be a better investment.
