1 Laptop won’t turn on - fans go full blast
Hi and thanks for any help anyone can provide.
My laptop is a Dell G3 15. When I turn it on the fans go on full blast and the keyboard lights up. The power light flashes amber 3 times then white 5 times.
I have tried the following;
- Disconnecting the power supply, the battery and the coin battery and holding the power button for 15 seconds and re-assembling
- Holding D on start up and the display test does work.
- On separate starts removing 1 at a time; removing the hdd, the ssd, the ram, the keyboard and light, trackpad, fans, display and speakers
- I replaced the motherboard with one bought from a reputable company and still no success at all

Hi,
Are you sure that it is a 3:5 blink error code as it's not shown in the service manual diagnostics list ?

Hi jayeff. I am sure. I have a video of it but do not know how to show it. Thanks

Don't know the laptop but is the CPU removable?
Given that you've replaced the motherboard and disconnected everything else, one at a time there's nothing much left to try.
Does it do this on the battery only as well as on the charger?

I tried adding the video following that and got an error code. Made it into a gif and got the same error.
It does it on battery as well as charger.
The motherboard is part of the motherboard so was changed when I swapped them
