Hello, I received this laptop with no power issue.
Originally short on mosfets of 1D05V_PWR
after removing mosfets I do not get the 3V LDO from TPS51225R(PU4502 3V/5V IC) (see on the attached image what I get in blue).
I have replaced 2 times the TPS and same issue, the 19V line from the charger is steady, my undestand is that the TPS only needs the 19V to provide the LDO but I get that noisy voltage.
I have cut the LDO trace coming out the TPS and same issue measuginr on the IC.
Any help?
thanks

HP Omen 15 DAG3DBMB8D0 strange 3V power rail
Hello
I have this behavior on the 3V rail (PL101 capacitors side) (See attached image and Boardview).
-I thought it was the 3V IC and I changed it and it's still the same.(PU101)
-I injected 3V into the 3V coil and the PCH got hot (very slightly, 170mA). I removed US4 and the 3V power rail stabilized (3.3V stable) so I changed the PCH but it's still the same after replacing PCH. (Also replaced US4)
-The enable of the 3V rail (3VS5EN) is following that pattern to.
-The 3V LDO (+3VPCU) is stable.
-I measure...Last edited by Vesko356; 10-22-2023, 03:56 AM. Reason: Attached boardview removed and replaced with link.

Distorted video on Alienware with LA-F551P
This one has some history, display replaced, video flex replaced, somework done around the GPU area.
See attached picture. Seems like VRAM issue right? Is there a way to know which vram could be the problem?
I have not reflow the GPU/VRAMs.
Any recommendation? Thanks!!...

Re: IC Marking Codes and Datasheets #2
Hello
Could you help me with this one?

I think it should be a RAM IC.

Dell G3 3590 MB: 18839-1 No video
Hello guys,
This laptop arrived from another shop, it had shorted the 19v line due to a PWR_CORE_PH1 shorted mosfet, I replaced the mosfet and the computer turned on without video, suddenly the PCH died!! (3V shorted to ground) I replaced the PCH and the computer is turning on again but NO VIDEO!
Currently:
-System diagnostic lights blinking: 2,7 (indicates LCD Failure).
-Caps Locks and ctrl+alt+delete respond.
-Tested 3 different BIN files (Also 1 clear ME)
-Tested 2 known good LCDs
-DCBATOUT_LCD: 19.V
-3D3V_LCDVDD_S0:...

Thanks friend, I will do it, but before that.
Could you create another BIOS version to test? If possible...

Re: asus vivobook s433f x421fl r2.0 bios
Thanks friend, did not work. Same issue: power on but NO video.
I have all coils voltages except for VCCGT. VCCGT: 0V.
I still think it can be a BIOS issue. Any help?...
