Have EliteBook 840 G1 but do not know its BIOS password.
Tried resetting BIOS by removing both CMOS battery and the laptop battery for hours but the last BIOS setup still got loaded from somewhere and keep asking me for password.
I am now planning to flash BIOS with "HP Notebook System BIOS Update 01.48 Rev.A" from:
Considering that It looks like the Secure Boot is activated in BIOS my question is:
Do I risk having the laptop bricked after flashing BIOS in case Secure Boot and any other malware prevention related security options are ON?
If so, how can I flash BIO safely in that case without bricking the machine?

First off, removing any batteries in a laptop, either the CMOS or the main battery, will have no effect at all on any BIOS password.
Second, if the BIOS is password protected, you will not be able to flash it, as then what would be the value of assigning a BIOS password if you could simply run a file and reset it?
To resolve a forgotten BIOS password issue, a system board replacement is required -- and additional customer costs apply, HP has issued this post about BIOS passwords: https://support.hp.com/us-en/document/c06368824.
In addition, according to the Community's Rules of Participation (which you can read from here: https://h30434.www3.hp.com/t5/custom/page/page-id/hp.rulespage😞
4d. No posts shall include instructions or directions intended to bypass or subvert security measures, including passwords, locking mechanisms, fingerprint scans, etc., or to bypass any safety measures.
For assistance NOW, you have to contact your regional HP Customer Support location directly as they will confirm ownership of the PC before providing any assistance -- something we are not able to do from here.

Thanks for clarifying few things about this.
I will try the approach you were suggesting and see what happens.
As for the HP Support Community Rules of Participation around BIOS passwords, while I do appreciate the fact they exist and what they wish to accomplish, for this particular issue I think HP went too far and I do not think this is in the best interest of HP laptop owners. Forcing people to replace the system board due to this is just ridiculous. I do of course understand you have nothing to do with making of those rules.
Thanks again for taking your time to respond.
