My laptop bugs when I unplug the power.

Hello,

I have a problem with my Asus A7S laptop. Every time I charge the laptop, it crashes.
Let me explain; sometimes when I'm using my laptop, the screen freezes, the mouse stops working, nothing on my laptop responds, and I have to wait for it to come back (sometimes I have to wait 5 minutes).

I've noticed that I only have this problem when my laptop is charging from a socket (regardless of which socket it is, as it happens in all sockets, even at my parents' place).

So I tested something: while I was experiencing the frozen screen issue, I unplugged the power adapter from my laptop, and suddenly, the laptop restarts on its own (as if there were a malfunction at the connector level).
And everything works again, but it keeps giving me frozen screens every day, which is very annoying.

I bought an extra cable (the 'Mickey' plug that connects to the power adapter) thinking that's where the issue was, but it's the same. I also changed the battery, but it’s still the same.
I don't know if the problem lies with the connector inside my laptop or with the power adapter.
Or if it's another hardware issue.

I took a screenshot during the bug while running Process Explorer (more comprehensive than the Windows Task Manager).

Here’s what it looks like:

As we can see, the "Hardware Interrupts" line is what we're interested in, as I saw it spike at 80% during the bug and then gradually decrease when the bug was gone.

Thank you for your help.
I hope you can assist me because I've been dealing with this problem for 6 months, and I've never figured out where it's coming from.
Configuration: Windows Vista Firefox 3.0.6

    Here it is, I know this post is old, but I had exactly the same problem, and I just found the solution.
    My PC would freeze when I plugged it in.
    Anyway, check your power settings for battery/plugged in; for me, it's an Acer, and it's in Acer ePower Management. When plugged in, you need to set the CPU speed to maximum. ;)

    Hello
    Acer ePower Management is a small software pre-installed on Acer PCs,
    to configure how to power the computer.
    It must have another name depending on the brand of the PCs,
    yes that must be it, the CPU %.
    Did you notice a difference despite the noise?
    As for the noise, that's probably something else, surely hardware, probably the fan.

    try to standardize the performance of your PC on battery and on mains power.
    Without any guarantee. Or else you have an electromagnetic impulse. Do you have no way to get another charger?

    Hi
    The problem comes from interrupts
    Have you done all the updates?
    Try updating your BIOS
    To avoid the problem (I know it's not great), stop the interrupts process before unplugging, unplug, and the interrupts will necessarily recreate itself if it's a vital process.
    Try scanning with another antivirus than Nod, like Kaspersky, to see if it's hiding something else.

    Hello,

    yes I have done all possible updates, I ran a scan on all the drivers, it found no drivers to install, I did the Windows update, everything is up to date.

    I also ran scans with Kaspersky, NOD32, Malwarebytes, Spybot, Adaware, and CCleaner.
    They found nothing, everything is clean lol.

    So to stop the interrupts process, before unplugging the charger should I stop this process? And when I want to recharge should I not touch the process?

    Is this the only solution to avoid this?

    PS: on the internet they talk about PIO/DMA disk problems, I have this in my device manager:

    I took the first one in the manager, where it says "IDE Channel"

    There are no issues on that side.

    Hello,

    Do you have Acer ePower Management? Because I don't have any software that manages power under Vista; I only have the default power option from Windows Vista in the control panel, but I didn't find a line that looks like "CPU speed." The only thing I found is "Processor power management," and then I have to specify a percentage for the minimum and maximum.

    The problem is that it makes a terrible noise when I set the percentage to maximum; it sounds like a jet engine, which is why I keep it on minimum.
