Dell Inspiron 5402 Bios Password

[Chaminda4191]

Dell Inspiron 5402-5409 and Vostro 5402-5409 models may encounter an issue where the service tag cannot be saved after reprogramming the BIOS. The solution is to use attached BIOS images. 😁 But even after trying this, you might still encounter the same issue, right? 😁😁 Don't panic—the trick is to try pressing the ALT + F keys several times, perhaps up to 10 times, until you see the prompt 'Please select your laptop model.' After entering the model number, you will be prompted to enter the service tag. 😀😀 Good luck
