  1. On a laptop, your BIOS is probably soldered in.
  2. Here's some info:https://www.pctechguide.com/how-to-update-your-system-bios/replacing-your-bios-chip-how-to-update-your-system-bios. Per Kanewolf above, in a laptop it's probably soldered down. If the chip is in a leaded style package, such as a QFP, you may be able to replace it if you have good soldering skills. Otherwise, you're going to have to replace the motherboard.

    Hi, yeah I realised mine had two in-fact, was hoping that I could access the second one to fix the bad flash but haven't had any luck. http://www.ebay.com.au/itm/Dual-BIOS-CHIPS-for-LENOVO-B430-Y400-Y410P-Y430P-Y510P-Z710-G710-Z510-Z410/131142954077?_trksid=p2481888.c100675.m4236&_trkparms=aid%3D111001%26algo%3DREC.SEED%26ao%3D1%26asc%3D20160908105057%26meid%3Dbdc8db4e88cc4e7595cdec5cfc9cb519%26pid%3D100675%26rk%3D1%26rkt%3D15%26sd%3D131142954077&_trkparms=pageci%253Aacb0950f-3cb5-11e7-9c22-74dbd180d795%257Cparentrq%253A21ade79515c0a866eb330233fffd9a9c%257Ciid%253A1

    These guys meanwhile assure in their description that all one needs is an adequate soldering ability, which I believe I have. Was just wondering if it was worth purchasing.

    Hey Scott thanks for the reply, the bios chip I have is the one on the right of the following image (Winbond 25Q128FVSG

    Has 8 feet soldered directly onto the board, I was assured it was an easy fix by the Taiwanese reseller, who even offered to flash it for me. Was just wondering if you'd agree it's worth the $35 fee.
  5. Go for it. Be sure it gets flashed to the bios version you need. $35 is a whole lot cheaper than a new mobo!
