Notebook Boot and Lockup

I contacted support - "Janet" cut me off twice - she should be fired!
She didn't even point me to the right direction!
SO here I am now with my issue - I see a lot of people have had this same problem...this issue is caused by BIOS and it could easily be rectified if my laptop would have a CMOS battery but HP design team didn't include one. So now the laptop is simply out of warranty for 3 months and this happens - the laptop is blinking white led 5 times long 3 times fast. 
I have tried all the suggested methods already.
Long press on button and win+b
Long press on button 15-30 sec.
Disconnect charger , etc .
Disconnect battery...drain everything
Remove accessories etc.

Nothing works... simply overnight my fully maxed out specs HP Consumer laptop became a paperweight.
And to make things worse ... okay I'm out of warranty ... so support doesn't care anymore but I am willing to bring it in for repairs to a authorized service center nearest to my location but it turns out they only sell laptops here and won't repair them.
Even if my consumer product would have warranty then there seems to be nobody who even repairs them. No authorized service centers that have seen the issue before. And have the knowledge to repair it. I will not bring it to a third party repair center either because they will say probably that the motherboard needs replacing, simply because they don't have a fix.
