    HP 15 power led blinking .

    hi everyone
    i have HP with motherboard DAR62CMB6A0 rev:A
    the power led turn on and off (start and restart no fun spinning )
    3.3v on ec bios but not exist on main bios ,
    but after i press the power button the 3.3 v appears on main bios
    i try to flash the main bios but the bios programmer can't recognize it i try with different programmer and the same problem ; i think the bios ic(EN25Q32B) is damaged , i use MX25L3206E as replacement but the same problem .

      Usually on a R62 mb , dc jack light blinking is due to resistor failure. I solved this case few months back and it was resistor for sure. Dont remember exactly but the resistor was located somewhere between power switch and vga port. Hopefully, you can find out.

                  Have you taken the main bios chip from the motherboard ??And then tried to flash it with the programmer ??
                  What programmer are you using ?

                  Sometimes it is not possible to program the bios chip (sitting on the MB) with a cable and a clip ...
                  You may need (to buy ) another programmer to do it in this way ..

                                  Greetings badcaps community,

                                  I havent done this for a long time and want to start it all again, after some evil and annyoing illness.
                                  So I apologize in advance, if some phrases might sound a bit like gibberish or illogical to you.

                                  Im trying my best to fully describe what I plan to achieve and hope I was choosing the right sub-forum for my new adventure.

                                  I have a Elitebook 820 G1 and a Elitebook 840 G2 here.

                                  These ask for a password when entering the BIOS, but boot just fine from the internal SSD.

                                  I learned that desoldering...

                                  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.
                                  1. I tried clearing bios, resetting bios, removed the CMOS battery, removed m.2 ssd, wifi, and ram. Still black screen with CPU fan blasting.
                                  2. I tried using the Lenovo BIOS CD and BIOS USB, but neither worked. At least I couldn't get anything to work.
                                  3. I could only locate two chips that look like bios chips. Could someone verify this

                                  Intel Arc A380 videocard power limit remove - BIOS needed

                                  Hello everyone!
                                  The Asrock A380 low profile card (ID 8086 56A5 - 1849 6006) have an power limit of 45W. Intel removed the possibility to increase power using the software utility, anyway the card is in an proxmox machine that doesn't run windows.
                                  The same hardware is in another form by the name Asrock A380 Challenger that have the same VRMs and the power limit is at 60W. I searched online and found on another website an .bin bios file from the Challenger variant, that I flashed using an CH341a. Flashng worked well, I put the card in PC and booted. GPUz shows that new device ID is 8086...

                                  Hi and thanks in advance for any input you might provide!
                                  I have a Sceptre U550CV-UMRD8POTV83BB 4K LED (this is a dumb tv) that I bought new in August 2021, so It's just completed 3 years.

                                  Last Sunday I was watching a dvd and fell asleep for about half hour, when I awoke the tv screen was black and couldn't get the dvd menu to show, so I changed the input to antenna and had sound but no picture, turned it off. I then got online and found this great site! ....read many troubleshooting tips and this...

                                  Microsoft Surface Pro (5th gen) model 1796 - no power
                                  by PantherDave
                                  Hi all!

                                  I'm trying to troubleshoot a Microsoft Surface Pro (5th gen) model 1796 that won't power on. Motherboard model is M1007506-015. My priority is retrieving data, but the SSD is integrated so it looks like if I can't repair it it'll need to go to a data recovery company. I've done a little basic board repair before, but nothing this advanced until now. So please forgive my ignorance in advance. 😅

                                  I found the boardview for this laptop in the forums here, and am able to open it on my PC with FlexBV.
