Model ACW 100 CT (2005)
Board 19050 REV A
P/N 17527
Board functionally dead, the colon ( : ) between hour and minutes in the display the only sign of life.
The 110V AC to 24V AC power supply checks good, power in is the black wires (AC) to the Left of that is 4 diodes bridged into a DC rectifier test good individually.
That's as far as I get with out a diagram, none in the manual.

Anyone familiar or have a schematic please.
Thanks...

Re: Hp 15-dy2087nr white lights blinking
PWR-BT? looks like one. test and check the voltage should be 3.3V. never seen one with a secondary power button before.Last edited by crewdog; 10-26-2023, 12:30 PM. -
Re: Hp 15-dy2087nr white lights blinking
simple test is find 3.3V on your power button and ground it for a second and if the fan begins to spin you have a bad power button.Leave a comment:

Re: Hp 15-dy2087nr white lights blinking
Hi, the SIO or Super on/off as it commonly referred is a multi function chip that manages many of the board systems, its first feature is that when you push the power button it short circuits to ground the constant 3.3V line to it which "wakes" up the chip (see pic, the biggest chip) and its programming kicks in and sends current to the other necessary system controllers and essentially powers up the board.
The most notable feature is the fan spinning which tells the repairman that at least part of the chip is working...Leave a comment:

Hp 15-dy2087nr white lights blinking
Board DAOP5HMB8F REV F
Model OPSH
No bios battery on board
Power at cord 19.7, swapped cord 19.7V just to test, tested lid switch good
Plugged in, battery in, charging port light on solid white, press power button, no fan spin, charging connector
and power on light both blink white, not in sync, battery voltage 12.2 jumps to 13.0 for a second and then back and repeats.
Not plugged in, battery in, press power button, no fan spin, power on only blinks white until battery removed, battery 12.7 - 12.1 for a second and then back and repeats....Last edited by crewdog; 10-25-2023, 03:26 PM. -

Re: Tc-p42c2 code 7
Note: I did reinstall the original SN board back in and code 7 returns with all connectors plugged in, trying to eliminate the installation as the fault. thank youLeave a comment:

Tc-p42c2 code 7
SOS 7, service manual says SN board *, disconnected 2 connectors and ribbon from SN board and get SOS 10, original SN board TNPA5066 (suffix "OK" stamped) unavailable at shopjimmydotcom they said TNPA5066AC is compatible replacement. Received Part, looks the same, installed and now I get SOS code 10 with new SN board installed, removed cables and ribbon from new board and coded 10 as well.
The service manual says (checkpoint) "*use SC jig to isolate the board" which I can find no instruction of this jig in the book.
I am not really a diagnostic... -
