Backup and try. Confirm results. -
Re: need bios dump (EC+MAIN ) of toshiba C55-B1336
Thanks for your answer but unfortunately the same State...
Please give me important signals to measure tham
right Now ihave:
vin:19v
+3VPCU +5VPCU in stepdown section
Pin8 of bios: 0v
RSMRST: 0V
if you have schematic for this board please give it to me....Comment

Re: need bios dump (EC+MAIN ) of toshiba C55-B1336
Is the mb switching?? If so, then measure voltages at all coils first and report. There are lot of experienced members here who can help.Comment

Re: need bios dump (EC+MAIN ) of toshiba C55-B1336
Vin in SIO:
EC:
PIN1,PIN2,PIN3,PIN4,PIN7:0V (GND)
PIN5,PIN6,PIN8:3.3V
BIOS:
ALL PIN : 0V
Please Help me.... WHAT CAN I DO..Comment

Re: need bios dump (EC+MAIN ) of toshiba C55-B1336
It seems you have 3VALW And 5VALW at coil. 3V AALW should go to sio and from there you should get 3v at power button. Check SIO for corrosion,shorting or any componenets which looks suspect. Check 3 & 5v SUS voltageComment

Re: need bios dump (EC+MAIN ) of toshiba C55-B1336
SIO is getting 3VALW but One of SIO vin pin 88 there is no voltage Normly we get 3.3v there
and this pin is directly related with pin 8 of bios chip and other comp.
maybe there is a short
the resistance of this pin i get 10 ohm
3 & 5v SUS voltage available in the tow mosfetComment

Re: need bios dump (EC+MAIN ) of toshiba C55-B1336
Did you check pin 88 of SIO chips has continuity with other pins or 3VPCU_EC line?
Maybe line of 3VPCU was broke inside layer of PCB.
Did you measure resistance with plugged adapter? if pin 88 have connect to pin 19, 46, etc, could be the IC (RT6575A) get warm or hot
- Only one of 3 ICs (RT8068AZQW, with mark 13, PU4, PU5 and PU6) should be have voltage 1.8VPCU. Read schematic Quanta ZHK or ZQM. Easy to finding on google or s-manual
- I don't see IC charge pump (G5934RZ1U) for load switch, maybe only use double of Diode as charge pump.

Re: need bios dump (EC+MAIN ) of toshiba C55-B1336
After a lot of test this is result:
I measured resistance with plugged adapter pin 88 with 16.46.... i get 52.5OHM
Voltage Existe:
+3VPCU
+5VPCU
+5VS5
Voltage NO Existe:
+1.8VPCU
+3VS5
*** And i get S5_ON VOLTAGE IS: 2.56V Is it normaleComment

Hi all,
This is my first post here (I am very new to forums!) and I hope someone can help. I am looking for a full dump of the BIOS of a HP Proliant Microserver Gen 8 so that I can get this mini server running again. (BIOS version J06 2019-04-04, chip 25Q064A). I think my board was partially bricked after a failed BIOS update.
I got it second hand in this state and all the normal attempts at bios restoration have not worked. I have even desoldered the chip and tried to load the actual BIOS from HP, but it is missing some parts needed to boot the system.

The Samsung S49CG934SU monitor does not power on - no LED indicator activity and no response to power button. However, when 21V power is connected, it immediately draws 0.8A of current with no display output. The motherboard processor gets warm, and there is continuous reading activity from the W25Q128BV BIOS chip.
Suspected Cause:
I suspect the BIOS may have been corrupted during a power interruption while updating the firmware. The official website provides firmware updates, but they can only be installed via USB flash drive.

Hello engineers 😀,
I’m kindly requesting a clean and unlocked BIOS dump for the following HP laptop, as it’s bricked after flashing SP152727. The system now keeps rebooting, and the original issue was an Administrator / Power-On Password that I can no longer access.😏

- Model: HP 15-da2007ne
- Product Number: 8XF55EA#ABV
- Serial Number: CND0338P0D
- CPU: Intel Celeron N4000
- EC/BIOS Chip: [Add chip number from the motherboard or BIOS chip]
💀 Problem:😅
- Device shows “Administrator Password”... -

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.)
NoteBook Model name : Samsung NT955XED-KK51G(Galaxy book2 pro, i5-1240p, 15.6inch AMOLED)
PCB model name : Venus2-15-5G(REV1.2), Venus2-15 ADL NPC
