Hi all,
Model: HP Pavilion 14-ce3010nh 8BV97EA
Board number: DAG7ALMB8C0 - G7AL REV C
Issue: I have an HP Pavilion 14-ce3010nh 8BV97EA laptop. When plugged into the charger, it turns on, but there is no display, the fans do not run, and the processor gets slightly warm. Unfortunately, I haven't been able to figure out what the problem is. I've reflashed the BIOS twice without any success. No post. Already tried out with another ram stick with no luck
I measured the voltage with the HP turned on in red, and I measured their resistance with the HP turned off in green....

by dclass-proHi guys, I have this macbook a1278 which doesn't have any image on the display, but when I turn it on I hear the chime.
I found the L9008 choke open and reset it.
When I turn on the macbook I have about 3v on pins 3 and 4 of the display so everything is ok but I still don't have the image.
On the backligt pin 21 and 22 I have 0v but the fuses are all ok.
What can I check?
I tried another display from a macbook a1278 but from the previous year and it still doesn't work.Yesterday, 02:17 AM -

by s_henyaHi guys,
Anyone ever worked on this board before?
Few issues im trying to resolve:
1. Laptop will not power up without main battery connected (missing 3.3v line)- measuring on the 3.3v coil i can see 0v but for split second it jumps to 3.3v and drops again.
Is this laptop supposed to power on only with battery connected?
2. Battery voltage + line is getting 19v, for my experience 7.4v battery isn't meant to be charged with main line voltage- is this normal?
3. No display on laptop screen, if i disconnect the LVDC cable and connects...05-27-2024, 02:50 PM -
by mrfree2itaHi all, I'm looking at what seems to be a nice puzzle
A ThinkPad T14s Gen 1 that stopped working more or less a month after the warranty expired. I tried to boot both Windows 10 and Debian 12 from a USB stick. In the first case, the system just reboots after showing the Windows logo for a few seconds, while I'm able to see the Linux kernel crashing if I boot the second in failsafe mode.
Interestingly, some times (unfortunately it's difficult to replicate) I manage to boot into Debian 12 live. Moreover, the kernel doesn't seem to crash always at the same point during...2 Photos05-25-2024, 03:43 PM -

by Luke11037Hello everyone,
I have an ASUS Vivobook 14 OLED M3401QA which is not posting. Currently when plugged into power/turned on the power indicator will illuminate and the battery indicator will flash white roughly once every 3 seconds. Leading up to this it would sometimes turn on and then other times not turn on, furthermore it also showed a screen saying "new cpu installed, fTPM/PSP NV corrupted or fTPM/PSP NV structure changed" and then a screen telling me to recover the bios however it is no longer even posting at this stage.
The diagnostics steps I have attempted...05-25-2024, 02:34 PM -

by valente222I have this equipment that leaked moisture from the bottom, which the PQ3201 damaged the track and does not turn on the machine. remove all two mosfets from that area such as PQ3201(high) AND PQ3202(low). these feed the VCCSA rail. but on this track it has a very low resistance, approaching my absolute zero of my tester to ground (1.3ohm). Could the CPU be bad? I have made this measurement by desoldering the PL3201 coil, taking that measurement on the CPU side.
On the other hand, on the mosfet side, the PU3201 controller, which is the pwm controller, appears to have a damage since...Today, 12:52 PM -

by Dallen BryceHello all,
I just finished flashing a new bios on an HP EliteBook 650 G10, and everything works except wifi and bluetooth. After installing the necessary drivers, the wireless card reports code 43 in windows. When restarting the computer, i get a code 10 (could not start) on the wireless card in device manager. I suspect that this could be a mac address issue, but I don't know what address to set it to in the bios, or if this is even related to the problem at all. Any insight on this would be appreciated.Today, 04:05 PM -

The result of the logic board check is as follows.
