    CH341A programer (Not responding) , Freeze

    Hello

    I took the bios from my motherboard - succesfully can read the data from bios chip (Saved backup file on my PC)

    Downloaded new bios bin here but i cant write that to the chip (I have tried Asprogrammer, Neoprogammer) as soon as i click "write ic" the programs goes "Not responding" state and hangs there.​

      Check your write protection flag for this memory.

          The chip needs erasing before you can write to it.

              Thank you for the quick feedback.

              Just tried once again , connected the CH341A and verifyd the IC , read the IC info - all working good.

              When i clicked on Erase IC , Asprogram freeze and goes to "Not responding".

                  What about the protection flag?

                      CH341a can erase and read but can't write and blank check
                      by hasel17
                      So I am trying to repair broken thunderbolt FW on X1 Yoga Gen 2. The EEPROM chip is WINBOND 25Q80DVNIG. I already do a back-up and erase. But when I try to wrote new FW, it was successfull, but when I tried to read it, it still blank. when I try to do a blank check, it gave me instant error in address 0. I already tried two CH341A, already did the 3.3v fix mod, using AsProgrammer, NeoProgrammer, Colibri, and CH341A 1.29. But the problem still occurred. What I did wrong here? Can anyone help me? Thanks in advance. Here is the log in Colibri :

                      [Question] Ch341a and 5v to 3.3v with logic converter
                      by md500
                      zz0.8tpitu4y0i8zzI bought a ch341a (I'm waiting for it to arrive) and I noticed that the programmer has a bug that the data pins go to 5v when the VCC pin is at 3.3v (which is the voltage I'm looking for).

                      Instead of doing the 3.3v mod, I'm thinking of converting the 5v to 3.3v with an 8 channel TXS0108E through the ZIF socket but I don't know if that would work, because it has to circulate voltage and also information.

                      What I am looking for is something that will convert from 5v to 3.3v but without modifying the ch341a.

                      I can't buy the ch341a 1.6v that has...

                      bug of the month: write caching setting for the hard drive in device manager
                      by ChaosLegionnaire
                      i recently bought a new wd re4 2tb with 2014 datecodes. when i got around to testing it tho in victoria hd tester, the write speed was very slow at 14 mb/s with a 256 sector transfer size. when i increased the transfer size to 1024 sectors, the write speed increased slightly to 44 mb/s. read speeds and sector verify speeds were fine and at normal speeds.

                      so i just ass-u-med the drive's poor performance was due to it being an advanced format drive and i was using it on winxp. when i tried cloning my system disk to this wd re4 2tb drive and writing to it in linux, the write speed...

                      Thinkpad T440P bios repair after WIFI whitelist mod
                      by helpmepleasethanks
                      As per the the rules, here are the specifications of my laptop :
                      • Make and model number : Thinkpad T440P
                      • Serial number (S/N) : PB-03A7V7

                      2. Reboot and use the laptop for a bit : everything is working fine
                      3. Shutdown (no power) and upgrade WIFI with unsupported chip (AX210)
                      4. Boot up the device : bios warning, as expected
                      5. Shutdown the device again (no power)
                      6. Connect the 8-pin clip of a CH341a
