Hi, I hope some one has some advice for me. I searched the forums but didn't see anything relevant. I acquired two identical Dell 9010 Mid Tower computers from a business office upgrade (they were going to throw them out). Both of them have the same motherboard (00F82W). One of them works flawlessly. The other one had a corrupted BIOS. I tried flashing numerous main BIOS and EC files from the internet, but none of them worked. I decided to copy the main BIOS and EC from the working 9010 computer and successfully flashed the corrupted BIOS. This got the computer able to boot again and run norm...04-23-2025, 04:30 PM -
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).

When I turn on the device, it displays the message:

Hi folks,
My son clicked “Update and Shutdown” on a Razer Blade 14 (2022, RZ09-0427), closed the lid, disconnected the charger, and put the laptop in his backpack. The next day, it wouldn’t boot: only the green LED blinked, no fans, no keyboard backlight, no display. The chassis does get warm, so the CPU/GPU seems to get power.
What I’ve tried so far: disconnecting the main battery, CMOS reset with power drain (30s), using a different power adapter, and connecting to the monitor - same result.
I assumed that Windows Update was interrupted due to closing...09-14-2025, 03:46 PM -
