    HP 840 g1 6050a2560201 ram error

    Hi this unit has black screen, caps lock blinks 3 times (Ram error) and fans run full speed. I have tried flash the bios/clean ME region/flash Ec but still the same.
    It has DDR3L which is 1.35v and vtt is .67v . Any ideas welcome.

        DDR3_DRAMRST is 0.126v on both slots.

          ddr3L ram it uses, so DRAMRST should be 1.3V approx. So your reading is definitely wrong.

          Hp site has only update and not full bios. You can post your dump here so that someone can merge it with official update to rule out bios issue.

                but it will not last long. may be a month or so and it will come back. You need to reball the cpu.

                  Sharp 80” long short flash backlight error - Help
                  by Superbee_dad
                  Hello Sharp TV experts
                  Our Sharp LC-80LE642U displays one short one long flash error code which is a backlight error. I went into service mode and there were 8 lamp error counts recorded. I reset the count to 0 and did a reset. The last monitor error cause was 16 B00014639:12. 16 is the code for backlight error. I tried to power the tv up but went back into error mode.

                  > I checked voltages on the power supply board and they all check out .. including 3.28 volts at the error pin.
                  > There is power to the cpu and T-CONN and no faults found there. The cpu has a flashing...

                  How to program a specific flash region of a Nations N32G455RE MCU?
                  by Nikan.e
                  Greetings and salutations!

                  I have a device that uses an N32G455RE. Unfortunately, its flash got corrupted. I have a dump of a working chip.
                  How can I program a specific region of the flash or the whole flash without touching the RAM, option registers, etc.?
                  I do not have a J-Link debugger and won't buy one, as I am not rich.
                  I have flashed a Nucleo board with an ST-Link to a J-Link just to find out that the ST-J-Link only supports ST chips.

                  What would be the cheapest and easiest option to program the Nations chip's flash without touching registers etc.?...

                  Flash LG PK5 DEMO - CH431A ERROR - verification error on address 00000000
                  by kyrios
                  Hello!

                  I apoligize for my English. I need some help.

                  I have an LG PK5 in demo version and trying to repair it, I found the original firmware in this forum to flash speaker to the original version.
                  Without having any idea about these things, I give thanks this forum and other tutorials, I bought a CH431A programmer and I have tried to do all the steps but after reading the new firmware, in the "verification" step I get this error: verification error on address 00000000
                  Could someone help me to solve it, please?

                  Thank you so much

                  [Help] Lenovo Yoga Slim 7-14ARE05 (DA0LS3MBAF0) – 25Q80DVN1G Flash Is All FF, USB-C PD Stuck at 5V
                  by ekozeko333
                  Hi all,
                  I’m trying to recover a Lenovo Yoga Slim 7-14ARE05 with board DA0LS3MBAF0 Rev:F. I’ve run into an unusual issue where USB-C PD is stuck at 4.7–5V and the system won’t boot (keyboard lights flash briefly, then nothing).
                  🔥 The Problem Started After Suspected ESD/PD Fault
                  I experienced a power issue or ESD event through a USB-C charger
                  After that, the NX20P5090 power switch was visibly burned and was replaced
                  Now the PD controller always negotiates 5V @ 2A, even with known-good chargers
                  🧠 What I’ve Done So Far
                  Flashed...
