12 flashes I believe.
Now it wont power on at all.
Anyone know of a schematic on this set?

As the Elitebooks (820, 840 all gens) only show flashing Power LED and flashing CapsLock (continuously) + a very soft "ticking" noise near the DC Jack,
I wonder if re-flashing the BIOS might be of any use here.
As far as I understood, steady flashing either means insufficient power or a CPU/GPU/Motherboard issue. I use the original 65watt power supply.
There are so many threads out there, but most of the solutions involve flashing codes, which I dont have or claim that you MUST use the original power supply, do a hard reset, reseat the RAM, clean the RAM,... -
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... -

Hi everyone. Yes, another Samsung question. Sorry for those of you that have seen your fair share.
Background: I wanted another project to take some free time up and was looking in the free section of the local internet and saw a posting that said “free tv. Won't turn on.” I went to pick it up and at that point is when I got the word that there was a lightning strike close to the house and it hasn't worked since. At that point I really didn't want the tv but after making the trip and having the guy help me load it in the back of the truck I felt I should just drag it home.... -
Hello guys, i need help with this problem, I have a NM-D041 mobo, it came with low impedance in 3v linear regulator rail, the cause was a damaged EC controller ITE8227e-192. I ordered a new one and replaced it. This laptop have a different chip for keyboard management and it8227e pins for programming ITE chips are not accesible through keyboard interface, I flashed it using i2c interface pins with vertyanov programmer because laptop was dead and SPI flash didn't have power (only 3v EC) so it couldn't access firmware stored in SPI memory. I read SPI and extracted it8227 firmware from original BIOS...
