The Register (aka El Reg) reports:
Many [who installed the latest Dell BIOS update] now cannot boot up their machines. One typical explanation posted was: "Add me to the list Dell Inspiron 20 model 3052, updated on the weekend, woke up to a solid amber/orange light and a dead computer. Contacted Dell on facebook and this is what I was told "The updates Dell releases don't affect the system. But it would enhance the performance of the system" ummmm no....if they broke they need to fix it."
[...] Some users complained screens cycled through red, green, blue and white while others saw nothing but an amber or red power light and a dead screen.
The main model affected by the allegedly dodgy update is the Inspiron 20 3052, although a few users reported similar problems with Inspiron 3252s.
[...] Dell's initial reaction was to tell customers they needed to buy new motherboards.
[...] Although complaints in the forum date back to May 12, Dell took four days to offer up a possible solution... which users subsequently said didn't work. Dell has yet to send [El Reg] a statement.
Have we saved anyone from a big headache?

There are ways to program a BIOS EEPROM despite computer hardware lockout [github.io]. Preferably one might as well install a switch on the "write enable circuit wire".
