asus K52JR not starting. need 4MB bios rom

[ktmmotocross]

Have this asus k52jr that have some problems with 3.3v that loks like shorted. but after flash bios it came ok, but not starting. i measure that PM_PWRBTN# signal from ITE 8570 did not some but PWR_SW# did come to them. i think that ITE could be a problem but i can be even BIOS. Have somebody tested BIOS rom for K52JR with 4MB bios file?

Hi
Please help.
I have a laptop K52F and K52F.
After programming bios programmer through my notebook boots up fine, but I have a problem in that the CPU is overheating.
After 10-30 sec. I turn off the notebook.
There are still some special setup or BIOS CPU?

Thank you very much

Chip on board
A52F-SX627D_MB-K52F_rev2.0_ver.zip
I have now programmed this.
Everything works. The problem is LAN / can not run / error in the driver.
CPU still has 80 to 90 ° C fan is noisy around 4000 rpm.
But notebook is turned off or fall.

seems to me bad cooler , and only after cooler replacement we will see if fan is still high , if still high , then bios must be with clean region

For LAN card to work you need to copy MAC address to new dump. MAC address is printed on a sticker on the mainboard, find it in the old dump in hex and replace. It should be there 2 times sequentially, change both of them.

if the sticker is missing from mainboard then you are in trouble...
