Hi All,

I'm having a problem any expert help me please.

Samsung NP-R620, laptop is turning on but no beep and no display, no external display and no fan spinning. I can turn the laptop on with the power button and can turn off.

I replaced the ram with working one but problem is same. The battery connector getting 3.3V all around the motherboard has power GPU getting warm so its working but to me feels like the CPU not getting warm at all but around the CPU has voltage. So I thought it must be the bios problem.

Before I turn on the board the bios chip doesn't have any power, when I turn on the board the bios chip has 3.3V leg 1,2,5 and 6. I think this is way of this board works.
Bios-MX25L1605D, 2MB, 16MBit.

Seems the bios chip is working. But what is the problem that can go wrong. If you guys have Bios bin please give me so I can flash and try.

The actual bios.bin I backed up:

Please help me.

Thanks again.

Well, if you are flashing BIOS, then you are doing fine on your own, and we do not have the time to find the correct revision number of the bios you should be running, considering you have not posted the CPU TYPE, CHIPSET or REV!
