    Toshiba C660D-13Q BIOS

    Hello

    I bricked my laptop (using the BIOS provided by Toshiba ) and desperately need help.

    Laptop details:
    Toshiba Satellite C660D-13Q
    Part No: PSC1YE-00G009GE
    Serial No: 3B55884K

    Motherboard details:
    Hannstar J MV-4 94V-0 1052
    PWWBE LA-6849P Rev 1.0 2010-11-25

    I tried to reflash it with a CH341A programmer but without success... I am not sure if I have the correct BIOS...

    I believe I am flashing the correct chip, which is labelled U13. The chip details are:

    TS25L020A -VCF 1103W 108F34 (Terra Semiconductor, 256KB, 3Volt, SPI)

    If someone could send me the correct BIOS, and also recommend me a software for my CH341A device (it doesn't recognise the chip), I would very much appreciate it. If that would be of any help, there is a sticker on the motherboard that says "PWWBE v1.40 BIOS U13 CB5".

    Thanks

              The bios for this should be 2MB .The extracted update from tosh and all bios dumps around the net are 2MB. The schematic does show a 256Kb chip, which is wrong.So you need to source a 2MB chip first .

                  Thanks a lot for your reply.

                  There is another chip, U55, which actually is 2MB (see attached image). It is labelled:

                  Winbond 25Q16BVSIG 1103

                  Please note also the white sticker above the chip that says:

                  PWWBE v1.40 BIOS U13 CB75

                  I was trying to flash the laptop with v1.60 from Toshiba, so since that didn't work, I guess I must use V1.40

                  I was just wondering, in the official Toshiba v1.60 update (I managed to extract with the UniExtract utility), there are 2 folders, DIS and UMA and each one has 2 files: BIOS.rom (2MB) and EC.rom (128KB). Which file is for which chip?

                                  ASUS TP500LA BIOS request/repair/merge?
                                  by jbonavita
                                  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

                                  1- Update / clear ME: Took the non working bios, made a backup, and did this: https://www.badcaps.net/forum/troubl...theory/trouble...

                                  Lenovo Thinkbook 15 G2 ITL i5 (serial number: MP2BFZEF) bios request
                                  by Wahaz
                                  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....

                                  Flashing ASUS UX51VZ with correct bios
                                  by Flyview
                                  Hi!

                                  Happy to be part of this forum for my first post!

                                  Short story:
                                  I believe my dad's UX51VZ has an incorrect bios (v207) for a UX51VZH flashed onto it. I'm not quite sure what the differences are between UX51VZ, UX51VZA, and UX51VZH. The serial number of this machine is D5N0CY845932229 and comes up as a "UX51VZ-DB103P" when checked on this ASUS website. All of the bioses can be found at this ASUS website.

                                  1) Do I have the correct bios or should it be the v205 for UX51VZ? Is there something I can check inside the machine to make sure?
                                  ...

                                  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...
