Samsung Laptop Boot Issue

[omega7441]

Hey guys and gals, got a fun one!

Customer computer is a Samsung NP300E5C laptop.

BIOS sees the hard drive and optical drive.

When the power is pressed, it fires up, shows Samsung splash screen, and then reboots itself. On the second boot it shows the Splash screen again and then shows a boot menu with no hard drive or optical drive listed at all.

Hard drive tested good on our testing rig. Replaced RAM = no difference. I've disabled secure boot and a bunch of other options with all the same results. Removed CMOS battery to force BIOS reset with same result of no boot devices.

A brand new hard drive doesn't show up as well and a boot-able flash drive does not show as well.

I'm thinking motherboard, customer doesn't strike us as being competent enough to have done a BIOS \ Firmware upgrade and have it screw up. They swear it did windows updates (windows 8) and then the issue occurred.

Anyone got any ideas?

UEFI is supposed to be an improvement!

I see you tried disabling secure boot. Did you enable CSM? Every damn BIOS I see handles this differently and just disabling secure boot doesn't always work on some mobo's.

Go thru all the options and see what's up.

Yes, maybe legacy boot needs to be enabled?

Yes I did this.

Doing some digging on the other posts I am seeing that its the UEFI issue. I'm going to leave CMOS battery and all power removed from the system for a few hours and see if that makes difference. Everything I am reading so far says the mobo would have to replaced or the unit sent back to Samsung for repair.

Wonder how much that will cost.....

a customer recently returned a samsung laptop under warranty and they had to replace the motherboard...

One way i would try tackling this is to remove that drive, put in another blank drive or any working drive even if it has os on it, and turn off secure boot and see if it will restart or not, if it still restarts then try legecy and see if that works, if indeed it doesnt reboot and gives you some error of no os found or even tries to load some old os on there then you know the mobo is ok and this issue resides on the windows 8 harddrive software wise, uefi issue which i believe gets stored on the hard drive itself, if thats corrupted, then its the hard drive uefi thats buggered and you need to restore it somehow or just install os again, there is some kind of boot cd for win 8 that you can make and go into diagnostics there and do a repair. I have done this once and it was a pain to make the boot usb, but it worked. Hope this helps
