Hi to all!
i have ch341a programmer. iam trying to program MX25L6475EM2I-10G chip with 16mb file, bu the programmer software(v1.18) says ''FILE LENGHT, BEYOND RANGE OR IT WILL BE IGNORED''. What should i do? Thanks! -
Following this guide (https://www.reddit.com/r/thinkpad/co...g_and_flashing) i re-flashed my t480s BIOS using an external (CH341A) programmer. The flash didnt work, so i reverted back to my BIOS backup successfully. The BIOS in the chip and the BIOS backup file are identical according to windows' file compare. The revert, however, didnt work: the only thing the computer does is flash the power button 3 times when AC power is connected. I've tried unplugging the CMOS battery, holding the reset button and holding down the power button- no signs of life.... -
My pc updated bios through Windows Update and I was greeted with BLACK SCREEN WITH CPU FAN MAX SPEED. I don't think there is even a screen signal, because it triggers my monitor for a couple seconds and then the monitor turns off. I tried the other outputs as well.- I tried clearing bios, resetting bios, removed the CMOS battery, removed m.2 ssd, wifi, and ram. Still black screen with CPU fan blasting.
- I tried using the Lenovo BIOS CD and BIOS USB, but neither worked. At least I couldn't get anything to work.
- I could only locate two chips that look like bios chips. Could someone verify this

Hi,
I kindly ask for help with Thinkpad BIOS/ME repair.
Thinkpad W541 board bought from Aliexpress, so I have no service tag nor S/N. It is 1GB version Q1 (K1100 nVidia GPU). BIOS 2.23, EC 1.13, ME 9.1.32.1002.
It worked fine until I tried to remove whitelist.
Steps taken:
- battery out, CMOS coin cell out, laptop disassembled; I kept LAN/USB subboard connected
- i took SPI programmer (CH341A with 3.3V mod) and SOIC clip and did a full backup of all SPI flash chips (SPI1 and SPI2 - BIOS, EC, ME, GbE; SPI3 - video BIOS; SPI4 - Thunderbolt fw) for several... -
I have an LG Plasma TV 60PM6700 for the past ~12 years.
In the last ~3-4 months I have been having some issues.- Problem: It started with random picture disappearing (sound still worked).
Frequency: Happened about once a week.
Solution: Had to turn off TV wait a few seconds before turning it on again. - Problem: Then it got worse and the TV started to shut down and when turning on the no picture just sound.
Frequency: Happened about once a week.
Solution: Had to turn off TV wait about 10-20 seconds and turn it on again to solve. - Problem: TV shuts down
