Re: Blinking Power Button on Lenovo IdeaPad 3 15ADA05 GS450/GS550&GS750 NM-C821 Rev 1

Completely lost here. Have this Lenovo GS450/GS550&GS750 NM-C821 Rev 1.0, which turns on sometimes and works ok, and I can go to bios, although the power button is flashing.

Other times it will just won't pull any current above 0.01A from the PSU, ON LED is lit up and the power button flashing.

I have tried to flash this bios via SPI https://www.badcaps.net/forum/showth...ighlight=GS550 it fired up and informed that needs to reser nVRAM and wont keep TPM settings and just hanged there. After restart no picture as with the original bios.

I have Reverted the original bios and loaded up at first when I resoldered the BIOS (i went to BIOS and reset to defaults), then on reboot won't turn on or will pull 0.6A but won't show any picture or keyboard response.

I am attaching the DUMP in case you find issues with it.

I must add, no liquid damage or corrosion on the board or foul play.

Just note that some Lenovo laptops flash the power button when no battery is detected or battery is below 20%. I can probably create virgin file from official website, but you must provide me serial number, and be prepared to flash main bios and kbc controller as well. If you have the necessary tools for that, quote me with the serial number.

You can use the virgin bios from post #12 .To add your DMI (the serial number etc) from your backup you can find a text file at post #1 with the offsets to enter it manually with a hex editor, or you can use the attached CopyDMI script and some software,there`s a link to a Guide

"Guide: Copy DMI info easily with Hex editing software and Macro script"

You can use the bios from post #12 and add your own DMI info (seriel number etc) using the info at post #1 .Its essential though that you make a good backup.If you`re unsure if your original backup is good or not post it here on badcaps in a zip or rar ,don`t post it to an external site.If you didn`t make a backup before flashing another bios then you will have to use lenovo DMI tools, try the U1 tool https://www.badcaps.net/forum/showpo...43&postcount=5

I don`t know which dmi tool will work then. The bios you posted has no DMI, you could use the dmi from the bios at post #65 at least then you will have a working laptop with windows key
