I haven't done anything out of the ordinary. The computer works fine even with this issue (when it ocassionally turns on), I just can't shut it off, then the booting issue becomes a problem again. Thank god for sleep mode, however, this time I forgot to plug it in and it must've shut down during the night. And no, I haven't been travelling around with it in sleep mode.

There's no problem with heat, it's not slow, there's nothing out of the ordinary. It's performance is the same as the day I bought it.

Thanks for your help.

Mulhollands, if you haven't updated drivers, this sounds like the Bluetooth driver bug that messed up boot/shutdown.

If you disable Bluetooth, and power off / power on, does the problem stop?



If that does/doesn't do it, try doing the Windows 8.0 updates, then download the latest Windows 8.1 drivers (they should install on Windows 8 too), and see if that fixes it.

Then try upgrading to Windows 8.1, and do all the Microsoft Windows 8.1 updates - and double check the driver versions to make sure the Windows 8.1 upgrade didn't downgrade some of the drivers you updated before the upgrade.

If it isn't any of those, it might be a hardware problem, and all that above has given you a good base to report in a Technical Inquiry to Asus for an RMA.

Here are the Windows 8.1 driver update links:

Let us know how it works out 🙂

I'm currently trying what Darnassus recommended, "Try take battery out and leave unit without power for a day, then try turn it on", but what you're saying sounds very plausible. Hopefully I can boot it up and attempt to disable it.

The computer is already upgraded to 8.1 with all of the available windows updates (even the optional ones) as of the 15th of July, and the driver versions I'll be sure to check once I manage to turn the computer on.

Hopefully that won't be necessary 😛 I have a good feeling about the bluetooth thing. I'm quite sure I haven't ever updated the bluetooth drivers, since I don't even use bluetooth. If only I had bothered to turn it off.

Thank you for the links and the help!

Also, the pattern of the flashing lights are 2..1......2..1.......2..1......, where 1 is the drive indicator and 2 the wireless/bluetooth indicator, and not the other way around as I wrote in my original post. Which makes it even more plausible that it's the bluetooth acting up.

Mulhollands, the bluetooth bug was when using older BT drivers, downloaded from the JW download area, instead of the newer ones available in the JM/JS/JZ - or BT area listed above. What version driver are you running?

I can't be sure if I ever updated the BT driver from the factory default, but if I did, I definately downloaded it from the JW area. That's where I got all of my driver updates from. I can't check what version yet. 5-6 hours left until the computer has been without a battery for 24 hours. I'll attempt to get it working again and I'll update you on that information later.

Mulhollands, you can check what driver you have in the Programs and Settings Control panel, then find the same named newer version drivers in the JM/JS/JZ or general/central repositories for drivers.

Asus has a tradition of not updating drivers for products once the new versions/models come out, so you need to figure out what new products use the same hardware components in your model and hunt down the latest version. Especially for Windows 8.1, bugs were/are still being fixed and improvements made, so the drivers in the JW/JX/JH areas that haven't been updated much since release are out of date.

Have fun 🙂

I just plugged the battery back in and I can confirm that leaving the computer powerless for 24 hours made no difference whatsoever. Also, after having thought about the driver thing, I doubt that's the problem seeing that the computer fails to boot even up to the point of drivers being loaded. There's nothing but a black screen, the power button, the power indicator and the number lock indicator glowing (as well as the battery charge indicator (dependent on if I have the power cord connected or not (as it should be)), and the drive indicator and wireless/bluetooth indicator flashing in the aforementioned pattern.

Connected USB devices do receive power (tried with a phone and a chill pad), so at least it still works as a pretty large phone charger. The fans are blowing at idle rates, the external temperature of the case and the air from the fans are at "idle"-temperatures. However, the other day when I left it on for 20 minutes, just to see if it would start by itself, the fans began spinning really fast and it got quite loud, but I'd say that the temperatures of the case and the air was the same, if not even a bit cooler due to the increased fan speed. I just turned it off and have been unable to replicate that behavior.

There's no sound coming from the mechanical harddrive (the only harddrive) to indicate that there's any activity. If there was, I'm sure the drive indicator would function normally.

I don't know if there's anything else I can do to troubleshoot, but if anyone got any ideas, I'd greatly appreciate it.
