Toshiba C660 Laptop does not wake from sleep on Windows 10 1909
Hi everyone,
I've been trying to setup an old Toshiba C660 laptop with Windows 10 (version 1909). The one problem that I've encountered is that the laptop does not resume from sleep. The fan spins and power light comes on, but there is nothing (no backlight) on the screen and the num lock and caps lock keys do nothing, indicating that the laptop is completely frozen. Therefore, I have to perform a hard shutdown (pressing and holding the power button.) When I go to turn the computer on again, nothing comes up on the screen and the machine does not appear to post, although there is fan spin. The only way to revive the computer is to reinstall the battery.
The specs for this laptop are:
- AMD Athlon II P360 Processor
- ATI Mobility Radeon HD 4200 Graphics
- 2GB DDR3 1333Mhz RAM (soon to be upgraded to 4GB)
- 240GB Integral SSD
- Windows 10 version 1909
This problem does not occur on Windows 7 and Windows 8.1. I don't believe this is a hardware issue, given that the RAM has been tested using MemTest x86+ and the SSD is brand new (I've also tried a different brand of SSD.)
So far, I have tried:
- Reinstalling Windows 10.
- Using Windows Update provided drivers
- Installing the legacy Windows 8 ATI Mobility Radeon HD 4200 driver (via device manager)
- Disabling hibernate via CMD
- Disabling fast startup
Nothing I have tried has worked yet unfortunately. Could anyone provide any further suggestions please? If it comes to it, I may just install Windows 8.1, as that seems to work fine.
Thanks a lot, Ben.
