Replaced Motherboard for Acer Aspire V5-573P. Current BIOS flashed to V5-471P. How to change?

Hello everyone,

I replaced the motherboard on my Acer Aspire V5-573P. The replacement went smoothly, but when I booted, the BIOS displayed that the laptop model is a Acer Aspire V5-471. This comes to not surprise as the same DAZRQMB18F0 motherboard is shared across different models.

Can I flash the BIOS to my current model, or would I need a different BIOS chip? I did attempt to flash the BIOS to the latest available on Acer's website, but an InsydeFlash error popped up: "The version of ROM file is not newer than that of BIOS."

One of the big motivators of changing the BIOS is the V5-471 does not have a numpad, but my laptop does. When I hit NumLock, the keypad works, but the O, P, etc. keys start typing numbers, so I can't keep the keypad ON while typing letters which is quite annoying. Unforseen consequences!

Hopefully this is a solvable issue. Thanks for any assistance!

Do NOT continue to try to flash the 471 BIOS with the 573P firmware or you risk bricking the machine to try to fix an annoyance. While the mainboards might share many of the same components and form factor, the BIOS hardware is not one of them. If the 471 BIOS firmware version already on there is the latest available, then if it were my machine I'd put up with the annoyance. Hey, I'm already putting up with it on two of my laptops without numpads and can't say that I miss them that much or even that annoying. But I suppose if I was a CPA who just had to have a numpad, and didn't want to keep trying to brick my machine, I might be tempted to buy a bluetooth numpad from Amazon for less than $30 with free shipping.

Thank you for the reply. Fortunately the numpad works, I just need to toggle the numlock key each time. Maybe I'll just live with it. I should be able to just replace the BIOS chip though, right? I have a soldering station and am fairly proficient at soldering.

No. Live with it. UEFI bootstrapping involves more than just a gigantic single IC that you could manipulate like in the olden days if you weren't ham-handed. Pretty sure you'll be looking for another mainboard if you try to do so. Jack E/NJ
