Do I need to update the BIOS and why?
Updating this program is a deeper process than ordinary computer programs. This implies a short algorithm of changes. Basically, this is a fix for the incorrect operation of any rare components of the system or the addition of support for the latest processor models.
In the event that the computer works without problems, it is better not to deal with this program. And you don't need to update it.

- It is necessary to replace the outdated OS on the computer.
- In the event that you plan to overclock your computer.
- The system functions slowly or incorrectly due to errors in the BIOS code.
- The version you have installed is broken, causing the system to not function partially or completely.

I have an indestructible Dell Vostro 500 (pp29l) in my household, it lives and works for more than 5 years, but the trouble is that the battery stopped working in the first years of the laptop.
So it was operated as a desktop computer without a battery. But since the hands "itch", a battery was ordered on Ebay from DELL INSPIRON 1525 (this is practically a more powerful copy of the Dell Vostro 500). And we all know about the dislike of business laptops for non-standard equipment (even for chargers and batteries). In general, as I was afraid - the new battery did not work ... The laptop simply does not see it and that's it. Here I was upset and began to look for ways out of this situation. There were thoughts of opening the battery cases and changing Li-ion banks, but this is a collective farm, and it’s not a fact that the battery controller will work. Then came the happy thought of updating the laptop BIOS firmware. Moreover, in the description on the manufacturer's website, it is written about adding support for fresh processors and batteries to the new BIOS revision (this is Dell).
Now it's time for the update, and then an epic bummer happened ... The BIOS updater does not want to update the BIOS until you insert a working and charged battery for safe flashing. So, vicious circle. In order to install a new battery, you need to update the BIOS, and in order to update the BIOS, you need to install a battery ... Well, then I got a little stuck, and thought bad words about the manufacturer.
But it turned out that not everything is so bad, a firmware version without a battery is provided. Just need to do it with the key /forceit and it only works from under DOS.
We burn the bootable DOS image on a CD, as much as 17 Mb (). Boot from it, follow the next steps:
D:\>500_a03.exe /forceit(I put the firmware program and the firmware itself in the root of the disk)
After the firmware, the laptop automatically reboots and pleases with the further work of its owner.
