Mmmm im newbie with bios programmer but my steps seems ok, i cant read the bios… wrong something? I cant detect bios chip alsoComment

Don't post pictures unless asked.
The bios chip must be unsoldered from the board before writing or reading..
do not use the clip, you may have errors..if you do not have anything to unsolder it with,
solder wires between the programmer and the bios chip..
..here is a video for example..https://www.youtube.com/watch?v=DWWi...nnel=ThisIsHow

Hello,
These files were read from a non working HP 450 G7 Notebook.
The device was shut down during firmware update.
When powering on, display stays black and fan is spinning up.

Is it possible to fix this?
Thank you very much!

Need Clean BIOS/EC Bin File for Lenovo ThinkPad Yoga 11e - Stuck with 0275 Error CMS
Hello everyone,
I am attempting a repair on a Lenovo ThinkPad Yoga 11e that is currently stuck at boot with the error: "0275 error CMS" even after setup new bios battery and will not allow me to enter the BIOS/Setup.
This is a critical issue that I believe requires flashing the BIOS chip directly using a programmer (e.g., CH341A/RT809H), as standard software updates or resets are not possible.
I have opened the laptop and identified the main BIOS chip... -
Hello everybody!
To put you in context I recently replaced the battery from my HP Pavilion 15 bc400ns with a used one, everything was going good. The same day, I decided to update the BIOS, everything went good. The thing occurred after I let the battery drain iddling on Windows 11 for the second time to calibrate it that the screen did not turn on again, the computer was on but the screen did not turn, like it would not wake from hibernation. I decided to restart the computer but got no video.
The thing is that I had installed TeamViewer and could log into the computer... -
Hp Probook 450 G7 s# SCD0348W35 had a locked BIOS. Bought BIOS and EC chips off Ebay that were supposed to match this machine - the 450 G7. Flashed in the BIOS on chip i bought using a CH341. BIOS unlocked next boot. Some error to contact HP. Entered BIOS and reset to system defaults and rebooted. Machine worked fine but every cold boot the contact HP message popped and everything else worked as fine. Assumed the error was from EC chip not matching BIOS that i just flashed in. So i flashed in the EC that was supposed to match from the EBay chip i bought and instant brick.

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.)

Hi!
Went dumpster-diving and found a bricked Lenovo P14S in trash, few weeks earlier. Symptoms - no screen, no POST, no beep, just keyboard LEDs flashing on powerup. Mute button+LED was responding though, and the display self-test was still working (via the key combo Ctrl+Fn+Power held for some seconds, see the Service manual).
Incidentally, Windows 11 have recently started auto-flashing computer BIOS in our region. Even more suspiciously, Lenovo has released a BIOS update just few days before the PC was trashed. About a week later, the BIOS update image has been oficially marked...04-14-2025, 01:56 PM
