Dell Vostro 5470 Not getting Dell Logo after bios upgrade in Windows 10

Dell Vostro 5470 Not getting Dell Logo after bios upgrade in Windows 10.

Notebook rebooted:

1.Fireed power led,

2.Powered up hdd led for 2sec. Turn it off.

3.Stops ...

No Dell Logo, no beeps, can't go into Bios.

LCD test works OK.

Remove Ram module, powered up and listen beep's

Pressing END key and power Notebook does nothing.

Any idea?

Hi paryav,

Good work on troubleshooting. It seems like there was an incomplete upgrade of the BIOS due to system shutdown or wrong BIOS file updated. You will need to replace the system board on the computer to fix the issue. Please private message us the system service tag of the system. So that we can check and assist you further. To send a private message, click on my name and send private message.

Yes. I did it.

Laptop have Phoenix bios.

Phoenix Bios have has restored procedure from USB Flash.

This steps to restore BIOS:

1.Get USB flash below 4Gb.

2.Format it to FAT.

3.Get your flash update from Dell Store - xxxx.exe

4.Run cmd.exe and in command prompt run xxxx.exe /writehdrfile

5.Copy extracted Bios.cap to flash drive.

6.Turn off laptop.

Next step 7,8 may be not needed but I did it.

7.Disconnected all perihpericals including battery and charger.

8.Disconnect HDD

9.Plugged the usb drive on the laptop at the right side.

10.Hold END key

11,Pluged the powercord and relase the END key 1 second after the power cord is in.

12.USB led on stick blinked fast and we see Bios Recovery Process on screen.

13.After finish notebook reboots and worked fine.

Hi. I have the same problem that you had.

What does bios version you used? Can you send me the link for download?

For me, the recovery process is intialized, but after some time it displays: "Error 100 - Invalid BIOS Image".

Thanks.

Hello PARYAV


I did as you explained but nothing happened.

The differences are that my Vostro 5470 reaches the Dell logo. It starts loading that blue bar below Dell logo and also you can see the message "press F2 to setup and F12 to boot options". However, after it the laptop turns off and then turns on and keeps doing the same, as an infinite loop.

Once, I got to run ePSA Pre-boot System Assessment but it found no errors. But now I can't run it. If I hold any key (like F12, F2 or even Fn) the ePSA appears and tries to start but following, after 1/2 seconds the computer returns to the "looping".


P.S. I used a 4GB USB flash.

Hello

I tried this method but flash link didn't blink so that mean the laptop didn't read the flash

What is the solution

Sincerely

I have the same issue after upgrading Windows 10. I tried this but nothing happens, do you need to make the flash drive bootable or something like that? or simply copying the file to the drive will do?

I can get into the bios recovery tool through the flash drive but it says

system pfat was enabled. please enter the signed image

ERROR 100 - Invalid BIOS image!

How can I fix this? Why is it asking for signed image, isn't the .cap extracted from the dell bios signed?
