Hi,

I have an issue with my aunts HP 840 G1 - she brought to me to fix it after when she left over night it in sleep mode plugged into charger. Laptop decided to stop giving any signal and would not even boot and turn on LED.  I have checked everything, cleaned every single connector with IPA and have managed to have the LED to turn on and charge (there are no visible signs of any kind of damage inside btw). Now the laptop gives such error codes:

Could anybody tell me what they mean and how to approach it? The only thing I found is https://support.hp.com/us-en/document/ish_1997719-1528356-16. Is iGPU failing and whole CPU needs to be re-soldered?

Thanks for your help!
