remove Cmos battery and main battery before writing bios chipset, then reconnect both, plug in ac adapter and start laptop from power button. At 1st boot press F2 and write service tag, permanently disable absolute, save (apply changes), restart, press Alt+F to exit from factory mode.

Same result. Absolute is still present. and when I put the service tag and restart it no longer turns on.

Volinakis THANK YOU VERY MUCH FOR TRYING. BUT IT DID NOT WORK, THE ABSOLUTE IS STILL ACTIVE, THE PASSWORD WAS REMOVED BUT WHEN RESTARTING IT NO LONGER TURN ON.

I apologize, I wasn't careful to check my keyboard and just typed. I didn't notice. I regret this mistake, I hope it is not repeated later. I very much appreciate the support from all of you. It was just a distraction error.

Ops
i have empty chip already any other way sir , i thought backup is done lol

What do you mean its empty, have you erased it. If you havn`t erased it just make another backup. What programmer and software version are you using, are you using a clip and if so what type, is the chip type SOP8 or WSON8 , is the chip in the programmer support list , did you use Auto-detect or choose the chip manually.

I use 7-zip and winrar, i know how to use both. I`ve already told you your backup is bad. Open the bios with a hex editor and look at it, it`s mostly FF`s which means its mostly empty.

When flashing a BIOS always make a backup first. Take 2 or 3 different dumps and make sure they are identical.
On Windows, you can use the command "fc /b" to check if two dumps are identical.
Make sure that the dumps looks good, i.e. not filled with 0x00 or 0xFF. After compression, if the file has a size of only a few kilobytes, the EEPROM was most likely not read properly.

Additionally, please read the FAQ at: https://www.badcaps.net/forum/showthread.php?t=98665

I assume you`re using a clip and it didn`t have a good connection.

Please post the service tag, it is required. Your backup is not good it should be around 9-10MB compressed whereas yours is only 405KB .
