Welcome to Lenovo Community!
Can you try with downgrading BIOS to previous version and check with it, to perform this you have to enable Secure RollBack Prevention in BIOS. Please click the below link for all the necessary details.
Also check performing power drain option, unplug the power cord and remove the battery. Then wait for a full minute. Then try to boot the computer.
Also check with reset the CMOS memory before you give up on it.
Request you to try with this option, if the issue still persists then I will forward it to higher team.
Hope this helps.

Thank you so much for helping me out.
My thinkpad edge E530 is in working condition now after I flashed the BIOS using Phoenix Wincrisis Tool to newer version of BIOS 2.55.
But there is one problem left, Now my thinkpad wont boot without AC Supply. If I try to Boot the device with battery only, It does not boot- No Bios screen,No power to LCD display,only fan works in slow rpm.
But when I boot the device with AC Power is ON the device Boots after a Forced shutdown . And when the OS gets launched the battery is not charging. Then I pulled the AC Cable and re-inserted it. Then its geting charged. There is no problem with the Battery, I tried it on my friend's Thinkpad . It works fine. Is there any solution for this?

I am sorry for the delay in reply!
I am glad to hear that your system is now booting after using Phoenix Wincrisis Tool. But for this new issue suggest you to check with uninstalling ACPI adapter from the device manager. Remove the battery from the system & power on the system from connecting ‘Power Adapter’. Wait till the system boot completely and then go to ‘Device Manager’ then uninstall ‘Microsoft ACPI-Compliant Control Method Battery’ under battery option. After uninstalling shutdown the system, remove ‘Power Adapter’ and insert the battery then switch ON the system and check.
Hope this helps.

Don't be sorry for the late reply, I really appreciate your efforts. Thank you for the reply
Well, I tried your above suggestion about unistalling ‘Microsoft ACPI-Compliant Control Method Battery’ . But it doesnt solve the issue. I don't think the issue has anything to do with the Operating System. Since the issue of Not booting without Power Adapter started after BIOS flashing.
This must be related to BIOS only. Please provide some more suggestions. Is there anything I have to check within the BIOS itself?
Current Status of my Thinkpad 530:
1.When I switch ON the Laptop with Power Adapter Connected it doesnt boot up = Fan is working + No BIOS Screen + system fails to Load BIOS and OS as well
2. then I have to Force Shutdown it and press the power button one more time = System Boots and works Perfectly (No issue with the battery charging)
3.When I try to boot the Laptop without connecting Power Cable It doesnt boot. I tried the Force Shutdown and powering ON one more time. Still no Luck = No Power to LCD + No BIOS Screen + No OS + But Fan is working
waiting for your reply
