Re: bios lenovo ideapad 330-15ikb
Hello everybody.
I'm in need of help with a Lenovo 330-15IKB-81FE-NM-B452. Mosfet PQ1005 toasted and PQ1001 open and I have already replaced them. Notebook now turns on when plugging in A/C, turns off and on again with 70mA, no video and cooler running at maximum after staying on. (continuous behavior when connecting A/C source). PL1001 without voltage, everything else ok!
There was oxidation on the PU901 pads, it was removed and resoldered.
Attached BIOS for analysis and possible ME cleanup.
Thanks to anyone who can help..Last edited by Inforprint; 05-08-2022, 03:36 AM.Comment

Re: bios lenovo ideapad 330-15ikb
Hello Peste!
I tried, but with no good results.
I still have no voltage on the PL1001, with a resistance of 7.5ohms. PU 1001 is 2.0V pwm, and according to this datasheet (NCP81253) the output is low, but I don't know if it would be normal on the NM-B452.
In the PL 1002/1003 connected I have 0.853V in both, with a resistance of 0.2 Ohms. Processor heats up normally, but the board always turns on when plugging in the power supply, turns it off and on again keeping 0.77mA and fan at maximum after a few seconds.Comment

Re: bios lenovo ideapad 330-15ikb
I used this BIOS and it worked nice, thank you very much!
I have dumped the same bios.bin to 5 laptops ideapad 330 and everyone worked perfect.
How can I barecode the serial number, UUID, Computer Name for each laptop? (in the BIOS it says INVALID to these fields).
Every tool I tried does not work (H2oEZE, H2OSDE, Lenovo manteinance Disk). Is possible to unlock the EEPROM or edit the BIOS file before dumping it to a laptop? I tried UEFITools either but no success.
Thanks in advanceComment

Re: bios lenovo ideapad 330-15ikb
Hello Peste,
Thank you for the response. I'm pretty new on this and I have no clue where is the DMI stored, I have to know the offset or address range to extract that DMI you mention before, right?
Where or how can I find/know the hexadecimal range of the DMI you mention in the BIOS file? I tried but I get lost on that huge amount of hex numbers, I tried to find somethin like "serial", "uuid", but no success at all...
Thank youLast edited by Nordlig; 10-17-2022, 09:16 AM.Comment

Re: bios lenovo ideapad 330-15ikb
The DMI is in the interval from post#12
DMI 234000 - 235FFF
on this laptop model the DMI is coded..
enter both bios in the HxD program, search the original bios by the word (LENV), check the box and transfer this interval with (copy-paste) to the other bios...Attached Filesif you find these attachements useful please consider making a small donation to the site

Dear all,
I have recently fixed a Lenovo IdeaPad 3 15 ALC6 that was not booting due to a BIOS issue. After flashing the BIOS, the laptop boots up, but hard disk is not recognized in BIOS. Is says "Hard Disk : Not Installed". I have tried with 2 different drives (one that I know is working on another laptop) but I get the same result. I do not know if disks were recognized before I got the laptop and fix it, but I don't see any reason why not. I can boot on USB though.
Here the steps I have taken to fix the laptop:
- downloaded latest BIOS from Lenovo Website... -
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 -
