    Need bios for la-b091

    Need bios for Lenovo B50 mobo la-b091p.

    I've already tried some dumps, but none of them seems to be the correct one.

    (BIOS LENOVO A8CN33WW(V2.01))

    I've also reprogrammed the Nuvoton embedded controller NPCE288N.

    Problem is that doesn't post correctly. has no video on lcd nor external connector.

    thanks.

    This is the bios backup:


    Forgot to mention that it behaves the same with or without ddr3 memory.

      Hi, thanks for your dump.

      It doesn't works for me.

      I don't know if it is a compatible dump. I can not find the original one.(A8CN33WW(V2.01))

      I've also tried other dumps like $A8CN53WW(V3.06) and not work either.

      When power-on, input current raises from 13 mA. to 220 mA. ant past 5 seconds input current goes back to 13mA.

      CPU voltage are OK, but it stays cold.

      Any comments will be appreciated.

          Hi, there's only one bios inside the rar file, and as I commented at the begining, I've also reprogrammed the Nuvoton embedded controller NPCE288N with a file from another website.

          Thanks.

          Pd: this is the file programmed to kbc:

              There is no difference with this nuvoton 288 file, it behaves the same.

              It seems like main bios is corrupted or cpu/memory problem.

              Main bios receives pulses at pin 1, but seems to hang in the process. (only a few pulses, I think not enough to complete POST)

              Perhaps with the correct dump, it works.

                                    Hi, my laptop wont boot at all
                                    With original bios no POST, only LED lights
                                    With alternative BIOS from model TP500LN (flashed via programmer) the notebook works again
                                    Some issues
                                    A- with bios from 500LN, it won't update from bios of model 500LA (from 500LN v203 to 500LA v300)
                                    B- If updated from 500LN version 203 to 300, the battery stops being recognized

                                    Things I tried

                                    Hello, I have an old Dell G3 3579 (ST: 2WQ7LP2-8FC8) with a newer 8FC8 BIOS password. I have successfully attached to the flash chip (W25Q128JVSQ) on the motherboard with a CH341A programmer and made several modifications using Intel FIT (e.g., allow software SPI write) without bricking. I was also able to boot to a modified GRUB shell where I attempted to edit many BIOS security related options like BIOS Guard/Lock, Flash Signature Override, ME FW Image Re-Flash, etc.

                                    Unfortunately, some of these modifications like to Intel BIOS Guard failed because it is fused into the PCH. Also,...

                                    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....

                                    Hi everyone,

                                    I have been doing hardware repair as a hobby for some years now and recently decided to learn about repairing laptops as a fun challenge.

                                    I managed to get my hands on a "HP Pavilion Gaming 15-ec2523nd" notebook that only shows a white power LED and doesnt respond to anything.

                                    After initial testing I concluded the bios seems to be corrupted since all voltages are normal and there are no shorts. HP has a feature for a bios restore from USB with winkey+B for this model. This did not work.

                                    I have desoldered the bios chip (GigaDevice...
