I covered very early on in this thread, that that option did not work. Indeed, the entire option to go to BIOS did nothing but restart the laptop, and not into BIOS mode, but back into Windows.
I've had time to try again today.
Here is what i have learnt.
The laptops own monitor does not display anything.
The HDMI port does not output anything.
The VGA port does not output anything.
The system fan turns on at power on, but turns off about 7-8 seconds later. I don't know if this is by design (ie: only runs when the CPU is hot) or indicitive of a fault or shutdown.
The DVD drive remains powered, and the button to open the drive works until the laptop is manually powered down again, it still works after the fan shuts off.
The status light on the top of the laptop remains lit throughout the entire process of nothing occuring on either display ports, and after the fan shuts off.It remains lit until the system is manually powered off.
I've used a USB drive with a status indicator on it. It didn't light up at all, indicating it wasn't read.
To check the ports were working, I used a USB checker. All of the ports were receiving power, at the usual 5.0v, and plugging anything into the USB checker, reported a constant 0.00A flow. Which to me seems to indicate its powering the USB ports, but isn't making use of them, if iti sn't passing any current to the device. Which would also explain the USB flash drive not even flashing. Usually when you plug it into a device, or a device first powers up, the light on it flashes as the USB is quickly read one time as it identifies itself.
Unfortunately, I cannot attempt to boot from DVD. It's been a long time since I used optical media or had anything that could burn to them, as I now use flash drives, or my phone when i need to transfer data or boot remotely.
