HP 15-be002tu BDL50 LA-D702P Rev 3.0 Power's On But No Display!

[m041633n]

Tried Flashing the Bios from HP Website with CH341a Programmer
(Extracted the BIN File using HP's "Copy BIOS image in order to use it on other devices" option)

Tried the First One 081EC From the 5 BIN file's (081EC, 081ED, 081EF, 081F2, 081F3) which was extracted and decrypted already with the BIOS Update Utility from HP.
But still the Same issue
the Laptop's powering up, the HDD is not spinning nor the hdd led is blinking nor the Caps Lock led is blinking nor the cpu is heating, there is no display! Cleaned the RAM and the RAM Slot with IPA. Tested powering up the Motherboard alone without connecting any of its spares but still no luck.😛
No RAM Beeps! 😀

I will be happy 😊 if someone 😌 could help me on this issue! And it's very urgent! Thank you 😊 💓 ☺️

HDD not spinning is of concern. Test on another machine to confirm the drive is not defective.

Is it a SSD or a mechanical hard disk drive? Disconnect from the logic board and test again.

Hi I've Explained you everything in the post

Tested powering up the Motherboard alone without connecting any of its spares but still no luck.😛

Tried removing these things from motherboard and turned on

HDD (HDD is working fine on a different computer and its intact.), CMOS Battery, Ram, all the flex connectors, WiFi Card, Battery, including the power button flex cable (shorted the power button connector on the board to turn on) still no display! Connected the display cable only for display.

The 15-be002tu has a Braswell (BSW) N3710 CPU -> https://support.hp.com/au-en/document/c05161809

The 081EC bios has ME 11 firmware,so it is the wrong bios. Check all of the 5 extracted bios with ME Analyzer ,the chipset support should say BSW/CHT

[m041633n]

Tried it! But it didn't work 😕 😪

It's still the same.

Checked the Old Bios Backup with ME Analyzer it says BSD/CHT on the chipset support and checked the New BIOS 081F2.BIN it was matching the same chipset support

How to start checking with the multimeter on which component with what settings on the multimeter. I don't know component level checking. It would be better if someone has the same board and same issue like mine and explain how did they resolved it. Please Help 😊 desperate to solve this case.

😊 Thank You 😊

[m041633n]

Any solution 😉??

[m041633n]

Any help

There`s a power sequence on page 4 of the schematic,measure all voltages until one is missing https://www.badcaps.net/forum/troubl...hematic-needed

On which component SMDFlea?? I am really sorry 😞 that I irritate Professionals like asking these silly questions. Would you Please help me on this?? Thank you SMDFlea.

BTW I didn't flashed the SIO and I don't know how to flash the SuperIO using CH341A Programmer. Can you guide me on this please I don't have the Keyboard Flex Cable

Thank You SMDFlea!

[m041633n]

I tried reading the SuperIO ENE KB9022 Using CH341A But the IC Was not detecting! In neo programmer using these
pinouts

KSO3 GND PIN 4
KSI4 CS PIN 5
KSI5 CLK PIN 6
KSI6 MOSI PIN 3
KSI7 MISO PIN 2

Please Help me. I tried reading in TL866II ➕️ ICSP with no SPI DRIVER HEADER. But it shows only zeros. What should I have to do??

[m041633n]

Please help??

Are the Connections are correct 🤔
