No luck with above flash. Hit power button, keyboard lights up as do WiFi and Spk buttons.. Orange charge light flashes 3 times then stays solid.

Re: hp 640 g2 need bios dump

After finding a Flash in the forum called 640OK I loaded the chip, now the laptop has different symptoms.. Cap Locks key flashes 5 times.. keyboard lights up for about 10 seconds, CPU fan Hums.. but nothing on the monitor.

Is that bios you posted at #31 the original.Whats the history of the laptop ,has someone tried to fix it before ? .The 640 g2 has 2 different bios versions , N76 and N87.The bios you posted has version N76 .

Is this the 640OK bios you tried, post #1 - https://www.badcaps.net/forum/showthread.php?t=82222 .If you open that bios with MEAnalyzer you`ll see that the ME firmware is "Initialised" which means the ME FW is "Dirty" as its already been booted on another machine and married to the chipset.Thats why your results are different now.You need a bios with clean ME firmware.

Is the BIOS original.. No.. The BIOS has been replaced at one time before. After the BIOS was changed the laptop ran for a couple of months. The BIOS chip was purchased programmed online. Popped it in and it worked.

The BIOS I posted in 31 is what I read of the chip in the laptop.
The 640OK Bios is attached here.

Try these.If they don`t work theres others (N76) in this thread with clean ME firmware.

Not a bios issue. Try another charger for a start,a genuine one with enough wattage, and clean the RAM gold fingers with an eraser if they`re tarnished looking .
