Lenovo Ideapad S145-15IIL BIOS

[SMDFlea]

Hello, i have problem with BIOS in S145-15IIL. Laptop had problem with blinking power button. I've tried to copy DMI 622000 - 623FFF, but it doesnt work. Without editing BIOS laptop is working fine, but i dont have serial number etc.
EC DKEC24WW
I've used DKCN55WW.

I suspect my DMI may be damaged
Original BIOS in attachments.

Try this one, if it doesn`t work i`ll post another version.

Clean DKCN55WW works good, but laptop is dead when im trying to paste my DMI.
I used DMI from another laptop and it works, but i want to have my DMI




Is this file you uploaded with my DMI from ori bios?

Yes. Try it, and if it doesn`t work use the DMI from another, then change DMI with Lenovo Golden Key U1 tool https://www.badcaps.net/forum/troubl...24#post1622424

Hello colleagues, I'm also having problems with the BIOS of a Lenovo S145-15IIL Placanm-c711 serial number PF21GTSC. I'm sending you the original BIOS because I'm not very familiar with the hexadecimal tool yet.

Thanks for answering and helping me. I went to the link you mentioned in post 33, but it's not working. I get this message: "Invalid File Specified."

Try it again. If you can`t add the DMI yourself let us know

Hello, I have reprogrammed the file but I still have the same symptom, the processor turns on, heats up but I have no video, the screen doesn't even flash, I have tried with an external monitor and nothing, it is strange in this model because I have had the same problem with many Lenovos and entering the BIOS solved it but this one is making me sweat, as for entering the DMI files, I can't find a tutorial, can you help me?

It should boot ok without the DMI, check hardware and if you fix that can add DMI later

[diegito11]

Well, I've checked all the subsources. CPU, memory, always 3V and 5V source and everything is correct, the processor heats up quite a bit so I think it's because of the BIOS, worse as I told you, it's strange that I've tried several and it doesn't work.

Backup the bios chip again, open it with ME Analyzer, if it says the File System State is Configured then the PCH hasn`t even read the bios chip, if it`s Initialised the bios has been read. You can try another chip, look carefully at your soldering and for missing parts, then keep checking hardware, get the schematic if it`s available and look at the power sequence.

This image is the one that appears when I execute the original file, so I don't know if it was copied correctly or if that bios was already damaged. Regarding the chip, normally the reprogrammer detects when the chip is bad and this is not the case.

Let's see if I make a copy of the one I had later and look at it with my analyzer to see what comes out.

I put in the second photo the result of the bios

Your ME Analyzer version is very old, update to a newer one.

Well, one of the things I had in mind was to deactivate the RAM on the motherboard but I wanted to leave it for last as a last resort. Well after all I decided to reprogram a file to deactivate it and I see that another colleague has also put it in, and surprise it gave me a screen and bios light.
My next question is, since the integrated memory has been disabled, it would only work with the memory slot I put in it, right? And I couldn't update the bios to the latest version, right? Since I would deactivate everything again? it's right?

Yes and yes. Attached is bios version DKCN55WW (the latest and last one from lenovo support dated 22 Jul 2022) with your DMI + ram disabled.

I'va also a problem with this model:
Ideapad S145-15IIL- Type 81W8
s/n PF1BY7NE
Mainboard: GS44D/GS54D NM-C711 Re.v 1.0

I tried to program BIOS using the virgin one on post #7 but witout any success.

Power works and battery charge but if I press ON, white power ON LED start to blink and stops only if I keep pressed power button.

I also tried to use an other DDR4 on RAM slot and removed it.
Reading other posts make me feel that problem may be in the BIOS so before to erase chip I made a backup copy fo the original that attach here.

Continuing reading the thread I wanted try the one of #33 and machine finally worked but was really instable and sometimes fan did not spin and machine was blocked with black screen. I sorted out that maybe this was a problem with defective onboard ram so I wanted to reprogram BIOS with the BIOS of # 77 No screen output - cap prob? At first it seems that this fixed the problem but while I was testing with Windows running it shut off for itself and I took a lot of tries to make it work again.
I really didn't know what was going on because mainboard was in good status but while I was examinating I saw just near the CPU a sort of dirt. (see pictures before and next with microscope).
I claned it carefully and next laptop started to works properly.
So I reprogrammed BIOS with the last one of post #33 and next I updated it again via Windows so it update also the EC part.
Finally with U1 Tool I was able to insert DMD.
