I have an Asus Notebook (x50R model). Is a really old laptop with like 10 years

I have a problem I can't understand:

  • If I press the power button it doesn't start
  • If I unplug the power and remove and put the BIOS battery (or press the power button for a minute) it starts correctly again, even can turn on and off multiple times, until I unplug the power, after that the power button does not work again until I reset the BIOS config again.

I tried flashing the last version of the BIOS firmware (502) but didn't work.

Also tried playing with the BIOS config: enabling and disabling the fast boot or the silent boot with no results.

Any ideas?

It might be that static charge remains on the motherboard and prevents it from booting up, so the motherboard refuses to boot up to prevent damage.

You can dissipate the accumulated charge by removing battery and power adapter and pressing and holding the power button for half a minute. After that, plug the power cord back and try to reboot the computer normally.

If the above procedure helps, even once, then accumulated charge is indeed the problem.

You may solve the problem by buying an anti-static mat, or by grounding the static electricity by touching the internal metal frame of the computer's case while it is plugged into the electrical socket. It is also possible that this is a problem with your power cord not being properly grounded - use a three pronged plug and a grounded outlet (and if that helps then you have a short-circuit or a non-isolated power cable touching the motherboard).

A better solution may require help by a professional.

You have mentioned that you remove the BIOS battery (this is generally called the CMOS battery), and I assume you put it back in. Have you tried replacing the battery? It is usually a CR2032 lithium battery, which you can pick up quite cheaply online - make sure to check the battery on your particular device and ensure it is the same.

When the CMOS battery is flat, it generally just means that the stored settings in the nonvolatile BIOS memory are erased every time the device loses power, but I have seen a few examples of it causing a device to fail to power on.

I would also recommend checking the power adaptor, power supply unit and battery for damage or defects and consider obtaining replacements if necessary. If there are no obvious defects, check each components individually (e.g. try to use the laptop with only the battery, use the power adaptor to charge another laptop if possible, etc.).

Try press and hold the power button about 5 seconds to power it off. Then press it again, this time in a normal way - don't holding it.
