i have v1.01 bios do i really need to update to 3.00 the update only says (Fix CPU temperature between T1(50¡ãC)~T2(90¡ãC) does not meet the fan duty.) my laptop does get hot but never shuts down plus i have a laptop cooler.
Most people don't have an EEPROM burner with the software necessary to program the BIOS chip.
I have bricked a couple of motherboards from this - and generally the manufacturer will charge you $40-$50 for a new BIOS chip (with the latest BIOS installed). 1) If you dont want to be afraid of updating your BIOS, or you bricked your laptop and don't want to pay $40-$50 to a greedy manufacturer for basically nothing, I recommend that you buy USB SPI flasher + SOIC-8 test clip (which cost is less than $10 from China) So that if you bricked your laptop you can tear down your laptop and use these tools: attach SOIC-8 test clip to BIOS flash chip on a motherboard, test clip connects to USB SPI flasher, which is plugged in to other computer.
That other computer, after the installation of necessary driver and flashing program, can either read binary images of BIOS stored in this BIOS chip, or write your own BIOS image that you have to that BIOS chip.
Basically all these "repair services" are ripping off people because people are stupid and dont know how to fix their computers for themselves...
On virtually every computer available, the BIOS makes sure all the other chips, hard drives, ports and CPU function together.
Every desktop and laptop computer in common use today contains a microprocessor as its central processing unit. To get its work done, the microprocessor executes a set of instructions known as software (see How Microprocessors Work for details).
You are probably very familiar with two different types of software: It turns out that the BIOS is the third type of software your computer needs to operate successfully.
2) - you could get a Coreboot open source BIOS (which supports Lenovo G505S) and flash it to your laptop!

Because its open source, you can modify the source as much as you want, everything is unlocked, performance is improved, as well as a speed of booting, and no Wi Fi whitelists or other stupid restrictions!
One of the most common uses of Flash memory is for the basic input/output system of your computer, commonly known as the BIOS (pronounced "bye-ose").
