Now I want to change my SSD configurations but I cant so help me with that to unlock.
Kindly let me know the steps...
Serial Number: PF0ZHQGC
BIOS Version/Date LENOVO 4KCN30WW, 8/31/2017
System SKU LENOVO_MT_80WK_BU_idea_FM_Y520-15IKBN

Hello,
I have a Lenovo Thinkbook 15 G2 ITL i5 Laptop (serial number: MP2BFZEF) that when I turn it on, the led on the power button lights up for 5 seconds, then goes out. There's no display and nothing happens.
So I thought it was a Bios problem.
I found 3 bios chips on the board, which I read with a bios programmer: two XMC model bios chips and a Winbond model bios chip. Each XMC model bios chip has two partitions named XM25QH128A [3.3V] and XT25F128A [3.3V]. And the Winbond model bios chip has three partitions named W25Q80BL 3.3V, W25Q80xV 3.3V and W25Q80DV 3.3V.... -
So a couple of years ago i got a bios update through Lenovo Vantage, so i installed it and bricked my whole BIOS, so i couldn't fix it so i put that ideapad in a box, 3 years later i found that one PC and want to recover it to switch from a 2014 hp laptop to this one.
I found a method to recover the BIOS of many lenovo laptops tha consists in pluging in a USB Flash with the BIOS files and power on the laptop with Fn + R keys pressed until fans go loud and start beeping loud, but nothing worked, so i think filename is wrong, i tried naming the bios file as 07WW.BIN, BIOS.BIN, BIOS.fd,...10-11-2024, 03:12 PM -
Hey guys,
Hope you all are doing well. I come here from Win-Raid because I am having issues disabling Flash Protection Range Registers so I can flash my BIOS from within Windows using Intel's IFW tool/using flashrom within Linux, however I cannot due to the above mentioned error.
Here is my thread on Win-Raid detailing the whole process I went through: https://winraid.level1techs.com/t/re...h-gen/95478/27
Essentially I managed to boot into Windows while shorting PINs 1+5 of my audio chip to disable the HAP bit... -
my laptop is lenovo flex 5 14ITL05
recently my power supply for this laptop developed a fault.
which caused a short in my usb c port -- verified with a new charger.
rant: so, i went to the repair tech in my country, he asked for a huge repair cost when i decided to get it done someplace else this "great person" nicked my bios chip, asked me to be aware for repair scams lol.
I was stupid and unable to find the flaw at the moment. Another repair tech told me that my bios chip was stolen and an 8mb bios chip is in place of that. he told me that a 32... -

Hi, my laptop suddenly shut down while it was running. When I try to turn it back on, the screen stays black and it emits a melodic beep.
I used Lenovo's SmartBeep decoder and it returned error 0284:"TCG-compliant functionality-related error (possibly BIOS code validation failure)"
I then tried to enter crisis BIOS recovery mode by pressing Fn + R at boot. The melodic error code changes, but nothing else happens regardless of whether a USB is inserted. I receive another...06-16-2025, 12:06 PM
