So this problem started following a full system reset using the windows recovery utility. Now, the laptop will only boot when the AC adapter is plugged in. If the adapter is then removed, it works fine on the battery, however if booted without the charger plugged in, the power button LED will light but the fan or display do nothing. The button then needs to be held down for 10 seconds to switch the LED off. I have already purchased and installed a new battery, and the same happens with the original or replacement.
I have tried re-running the recovery reset a few times, playing with BIOS settings and uninstalling/ reinstalling the battery in device manager but to no avail.
Any suggestions on what to try next?
Thanks for any suggestions!

When you start up your laptop the battery needs to supply sufficient power to the hardware components to boot normally. The same goes when the charger is plugged in. However, based on your description, it indicates that the battery is not supplying enough power. It sounds like not the battery, but other hardware components or sensors on the laptop. We can update the BIOS first, and see if that addresses this issue. To update the BIOS, please enter the serial number here https://support.lenovo.com/gb/en/, then go to the Drivers & Software tab, select the correct Operating System and Component. After installing the BIOS firmware, reboot your laptop and observe. If the issue persists, we recommend contacting our phone support to get it repaired. As this issue, needs a physical diagnosis of the technician. You can reach them at +44 333-777-3991 (National Rate), option #2 9:00-18:00 Monday-Friday.

Please access BIOS and set the Boot Mode to Legacy then save it. Switch it back to UEFI mode then save. Load default settings by pressing Fn + F9 or F9 only then save and exit by pressing Fn + F10 or F10 only. Wait for it to boot up, shut it down again and turn it on without charger plugged in. Update us how it goes.
