    This is a new HP 15 BS576TX Intel laptop with Insyde F.22 (version) BIOS-UEFI provided by HP. The laptop has hybrid graphics - Integrated Intel HD620 and AMD 520 radeon 2GB dedicated card. So, HP Support Assistant showed a BIOS update to F.24 and I clicked download and install. Installation menu showed flashing went 100% as well as verification. However, there is only a black screen now if I press the power button ON. I tried these steps and none of them worked:

    1. Win Key+B + Power button

    2. Win Key+B + Power button with USB recovery BIOS

    3. Removed battery and AC power. Pressed the power button for 30seconds, 1 minute and 2 minute.

    4. Win Key+V - and does the same thing. Pretty much nothing is shown.


    During all these steps, laptop switched on and hard drive led is blinking once in a while (I imagine it is in a gap of 4-5 seconds). I remember BIOS flashing showed 100% and verification also confirmed.

    Well if it is brand new... Contact HP and get a Return Merchandise Authorization. You'll probably get another replacement laptop

    Since it is 14 days over, HP is telling only repair service. :(

    I have removed the battery and plans to keep the laptop this way for few hours and going to try again. If CMOS battery voltage gets lowered, is there any hope the BIOS will restore? //Sorry, I'm not that knowledgeable regarding BIOS-UEFI. Is this a sure case of Motherboard replacement? :eek:

    As regarding warranty, HP chat support has assigned a case number and technician may come for repair. I'm thinking of taking the laptop to the reseller from where I bought

    HP has DoA policy of only 14 days here. After that they offer only motherboard replacement in case of BIOS corruption.

    Back up any data you have on your hard drive. They'll probably come out to look at it and determine you need a new board and take it with them. There's a very high chance that you will lose anything currently on your hard drive so if you need anything, connect it to another pc and back up what data you need

    Gave it to HP service. So, they are replacing mainboard/motherboard as the guy said something similar to bad flashing problem common with hp laptops with dedicated graphics card. So, it is a week's time for replacement of the board. I see that there's some chances for replacement laptop too. Learnt the lesson the hard way, still : if it ain't broken, don't mess with it. Truly! No more BIOS updating from my part.

    Actually I've most of the data in my desktop pc and still some personal datas are left in the laptop. HP service said, if you want, you can take the laptop any laptop repair service and do manual backup from hard drive, if it's critical data. I think they may not do a DoA replacement now. Will update once I get back the laptop.

    Even if they just replace your board, it's not unusual that they will wipe your drive and put in a fresh install of HP bloated Windows

    The laptop came with FreeDOS only. But, I got a legal copy of Windows 10 and Ubuntu Linux installed..took time to install and configure all these. Let's see. Will update.
