X550 Craziness - Need help before my head implodes!

Level 7
I press the power button on my X550L laptop and it doesn't start

Sometimes I press it and it does start

Other times it starts 5 minutes after I press it

And sometimes it starts 30 minutes to 1 hour after I press it

It's random!


I do a variation of removing battery, or mains power, and holding down power button for up to 1 minute etc.. Reconnecting battery and or reconnecting mains power and pressing start again

It's just as random. Sometimes it starts, other times delayed again

It's really hard to work with. I just don't know if or when it's going to start up


Anyone else had this trouble?

I was thinking of upgrading the firmware but I cannot find X550L firmware updates anywhere


Perhaps I should reset the BIOS to default?

I just don't know. And I just don't want to make anything worse

Thanks for your feedback!!

Its looks like a bootup issue! there can be a faulty hardware which is causing this bootup issue, and when it starts working your system gets boot up.I think you should check the other hardware parts like ram and hardisk before updating your bios.

I ran Windows Memory Diagnostics Tool. It reported zero errors

I checked my Hard Drive via Device Manager. It says that there are no errors

I'm looking for a more substantial ASUS Diagnostics Tool that will help me check the whole Laptop but there doesn't seem to be one available???

Only one I found is a few years old ASUS PC Diagnostics Tool v1.45

Are there any others out there?

I feel as though I cannot do a proper hardwarre component check

Can anyone help with some advice please?

might be motherboard issue or devices nor connected properly on motherbard
or heat sink is not proper
