I asked for consumption on your dc-supply. Are you powering the mb from adapter??

Hello.
I have a problem with this laptop DELL INSPIRON 15-3521 (Motherboard VAW01 LA-9101P REV 1.0).
At first it came with 1 beep code continuously and no picture. I flashed the bios with programmer and it turned on but now some times, not always, it does not turn on and gives 5 beep code, which Dell states it is Real Time Clock Power Failure. The cmos battery is new. If it boots up correctly, it stays on and works perfectly.
Do we have any idea what it could be or where to start diagnosing? I have schematics and boardview.
Thank you. -
I saved the bios dump (attached), i checked it with uefi tool to get an idea of the cause, but i have no idea what to look for.

For the future adventurer: Before someone gets confused like me for a second, the bios chip is U49(SPI FLASH 16Mb), do not mistaken it with UT2 (8Mbit Flash)... -

Hi,
I try to repair an old Intergraph TDZ 2000 from 1998. It is a dual Pentum II machine based on Intel 440LX chipset. There is a non-removable bios chip named PhoenixBios B1787840. I cannot see any physical damage to the board. All caps look OK.
It shows no picture and POST stops with code 2F/2E regardless whether or not any graphic card is plugged in. If memory is removed, it stops on previous code 28/17 and stars beeping. I tested both CPUs in another machine and I also use RAM from another machine.
When I recorded video of POST card and played it in slow...
