It has been more than a year that the bad bios updates (from update 1.2.3)  started problems like the crashing of graphics hardware, overheating, low performance, and cracking audio on the battery. Now even 1.3.1 is out but Dell didn't fix the bios, and now there is no way to downgrade below 1.2.5 (which also contain the same issues). Is Dell even working to resolve the bad bios updates or it's just a cheap business trick so that people will buy their new products because it doesn't make any sense they just add issues with every bios update
