I am having an interesting issue with a Toshiba Satellite Model: S70t-B Laptop I bought 2nd-hand recently.
1. I can start the laptop normally and its boots into windows without issues.
However, as soon as I either restart, shutdown or try to put the laptop to sleep it will perform the action but the laptop won't turn off. The power button light on the keyboard stays on and fan stays on.
2. This also occurs when NOT in windows. (e.g. If I go into the BIOS and change a setting and then save and reboot the machine doesn't turn off)
3. I then have to remove the battery (and/or AC power adaptor) to shut the machine down.
4. When I then plug the battery and/or AC power adaptor in again the machine LED power light comes on however I have to wait for around 3-4 minutes before it will start up again. If I press the power button on the keyboard the white LED power light flashes once only and nothing happens.
5. In addition to this strange behaviour, the Date/time in the BIOS and windows loses time very slowly.
So, I'm trying to figure out what the single white power button flash means. I suspect this is a motherboard issue and possibly a power controller problem maybe? If anyone has any ideas please let me know. I'd like to see if it's a simple fix I can do myself.
This is what I've tried doing so far but it hasn't changed the behaviour described above:
- Reseating the Ram, removing/Checking the HDD
- Checking for overheating issues. CPU and GPU running at around 45-50 degrees. Don't think this is a problem. I have also removed the heatsink/fan and put new thermal paste on the CPU and GPU.
- Turned off all the sleep settings in windows
- Updated the system BIOS to version 5.20 (latest version)
- Changed the CMOS battery to a new one
My Specs are:
OS: Windows 10 Home 64-bit
16GB DDR3 1600Mhz RAM
1TB HDD
Graphics: Intel HD 4600/AMD Radeon R9 M256X
I also have the following issue in Device Manager
Intel 8 Series/C220 Series USB EHCI -8C26 device cannot be started (Code 10)
