      Your bios backup is 1MB should be 8MB, so either you've dumped the wrong chip, or the chip is not read properly. Try again. Post SPI chip markings.

          Hello, My bad, wrong ch341a software . Here is a good backup and i have succes to flash the clevo website bios.

          Now the laptop stay on but always with fan at full speed and no picture. All power supply is up and running. Bios pin have 1.8v except pin 4 abd 7 so i thin no bios problem am i right ?

          I doesn't find any other n240lu bios file, only the file of clevo website, just other on vinafix but i'm not no registered.

          And no shortcut on the board.

          In the zip file from clevo there are an ec file, i think i doesn't need them but maybee i'm wrong ? Peraphs with bios update i have to update this ec file ? If yes is this possible with ch341a ?

          Thanks for any help.

                          Notice to users of XGecu TL866II Plus / T48 / T56 / T76 programmers regarding BIOS backup file size
                          by m1ch43lzm
                          Hi everyone
                          I noticed on the Xgpro software the BIOS backup files have extra bytes at the end when reading some chips, this is because the Xgpro software also reads the OTP region of those flash chips, and by default will append that region to the saved file
                          Programmer models: XGecu TL866II Plus / T48 / T56 / T76

                          Example: GD25LQ128D (1.8V), IC size is listed as 0x1000000 Bytes (16777216 bytes) + 0xC00 bytes, those extra 0xC00 bytes will be appended to the end of the saved file by default, resulting in a file size of 16780288 bytes
                          There's also an extra OTP Secu.R...

                          Hello,

                          i hope to find help her in the forum. It is a littlebit tricky. I searched many Days about disabling IntelME that was may major task. So i have a Clevo PD50PNN motherboard.

                          At first i tried to Backup the BIOS with tools direcly from Windows(normaly i am a Linux user). But no full success because not every part of the bios was readable. So i bought a modified CH341a for a Backup.

                          Backup worked but since the backup the Laptop is not booting anymore. I flashed the newest Version oft the BIOS with success, verfiy everything ok.

                          by Citymin
                          Hi all,

                          My Samsung Galaxy Book 2 Pro 15.6-inch laptop has no display and won't boot.
                          The charging red LED lights up, but the charging screen doesn't show any indication.
                          When I press the power button, the blue LED cycles on and off three times, then the screen doesn't turn on, and the device won't boot.
                          (I've tried removing the battery and resetting the device, but the issue persists.)

                          NoteBook Model name : Samsung NT955XED-KK51G(Galaxy book2 pro, i5-1240p, 15.6inch AMOLED)
                          PCB model name : Venus2-15-5G(REV1.2), Venus2-15 ADL NPC
