I managed to wrte the bios data, unfortunately it did not help
I'll try to flash the version I extracted from the sp155608.exe (downloaded from [url]https://support.hp.com/gb-en/drivers/closure/hp-envy-13-ay1000-x360-convertible-pc/2100744992[/url])
the exact product code is 13-ay1003nc, the 13-ay1000 is the closest version I have
compared to both my old and your version, this is different
will keep you posted
thank you for the help,

Thanks SMDFlea,
here are details I was able to find[LIST][*]HP ENVY x360 Convertible[*]Model 13-ay1003nc[*]ProdID 58W53EA#BCM[*]SN# CND1442RZ4[/LIST]I am having difficulties reading the BIOS chip GD25LB128DSIG, my EZP2010 reader can't detect nor read it when manually configured as GD25Q128.
It's 1.8V chip, I am using the low voltage adapter.
The laptop can't read the chip as well IMHO, so it might be dead or unreadable.
So I wonder if there is a chance to get a binary and flash it into a new chip.
Regards,

HP ENVY X360 13-AY Ryzen7 5800U board LA-J482P M76378-601/ M76376-601 BIOS
Hi all,
I have a HP ENVY X360 13-AY Ryzen7 5800U computer here[LIST][*]shows 5 long, 3 short capslock flashes when the WIN+B is pressed[*]turns itsef off after 2-3 secs otherwise[/LIST]based on the 5+3 flash code, I believe it's a BIOS issue
so I wonder if some of you guys have the LA-J482P BIOS on hand

Apple MBP A1398 EMC 2881 No backlit, PP3_G3H drops to 10.8V after start, 0V on LVDS pin 1
Hi all,
I have a MBP A1398 EMC 2881 here, it chimes, boots and shows picture on external screen
there is an apple logo on the display, no backlit
I measured the PP3_G3H on the backlit fuse - it's 12.6V when not powered and it drops to 10.8V after startup.
Is this OK?
Also measured the LVDS connector pin 1, there is 0V, could that be the backlit driver chip?
Also checked all 4 "backlit" capacitors, all OK, not shorted.
Thank you very much,

oh, the PCH is getting hot when the board is powered
also, as [USER="149220"]mcplslg123[/USER] mentioned [URL="https://www.badcaps.net/forum/troubleshooting-hardware-devices-and-electronics-theory/troubleshooting-laptops-tablets-and-mobile-devices/3247738-hp-13-ad017nc-doesn-t-start?p=3249181#post3249181"]here[/URL], the 1R4 to ground at 1V rail is "considered too low indicating perhaps towards a shorted PCH"

Raspberry PI-TOP v3 schematics
Hi all,
just wonder whether the Raspberry PI-TOP v3 schematic is available?
not the Raspberry PI itself, but this little add-on board:

that would be awesome @mon2,
if I can identify the rail, I may find the mosfet and the corresponding controller, one of these may be bad IMO
I wonder what rail is missing... could be something like B+?
the board is not labeled (no silkscreen), the coil of missing rail is R47 (0.47uH?)
this is actually an ebay find, not a clear history, not many signs of misuse of water damage

Thank you very much @mon2,
here are the measurements:
[ATTACH=JSON]{"data-align":"none","data-size":"medium","data-attachmentid":3263872}[/ATTACH]
I'm testing the board outside of the laptop, with no battery connected, this may explain the low voltage on the BAT line (?)
the resistance to ground on BAT is almost 500 ohm, looks OK to me
the VIN is 20.1V, sounds good to me either
