HP G35N no discrete videocard detected
Hi
all working great but GTX1050 discrete graphic card does not appear in device manager (clearly no driver request).
A wrong bios version could be the reason?
Or it is an harware problem?

AOC E2275PWJ dead
Hi
i have 4 of these monitors dead. No sign of life when i press the switch on button.
I think there is a problem with the PSU design.
Anyway, i suspect a sot23-6 chip but i cant find its specs.
on this chip i can read:
fist row:
73108a
second row:
. 559 (dot is the orientation mark).
Anyone can help me to identify this chip?
Thank you in advance

Re: Hp gaming 17-CD not recognizing M.2 HDD
[QUOTE=mon2;1193280]Hi.
1) post full silk screen markings from the logic board so we can try to locate a schematic.
FPC70-LA H472P rev 1
This machine suffered a small liquid damage in the area indicated in attached picture (far from M.2 connector, eeproms and chipset).
So i changed 2 capacitors and 3 resistors oxidated and now laptop runs smootly, if i load OS from USB key.
2) the last bios is probably for a EC/KB controller. Fancy name for a complex device based often on the 8051...Last edited by Slang; 12-31-2022, 05:26 PM. -
Hp gaming 17-CD not recognizing M.2 HDD
Hi
i have this laptop non recognizing nvme HD.
Probably i have an hardware problem, but my question is:
on the MB i can find three eeproms:
qh128ahig (main bios)
25q80 (video card bios, i think)
25q20 (?)
The third one what is for?
Is it possible the MB lost some info from bios/ME/SIO?
TIA

Bios and more for OMEN 15-dc1524na
Hi
i bought this laptop with bios and ME chips badly desoldered from PCB (but shipped with the machine). I repaired broken traces on pcb and read these chips (files are attached) BUT I AM not sure that their content is the correct bios or a wrong one.
In bios file i found DMI 08574. Is it the right one for the laptop?
I'd like to extract the original winkey (but it seems missing to me) and copy it in the new file.
Two years ago i bought a Win 10 license: can i copy my license key in the bios file?
Can you help me with correct files?
Thx

Re: Supplier for M.2 pcb connector HP 15-AX
Hi
thx for your answer.
original connector was broken and trashed.
It was like the one in attached picture: BUT the original one has 4 smd contacts (and not 6 like the one in picture) + 5 through hole contacts in left section; and 29 smd + 29 through hole at right (viewed from top).
Connector height should be 1.8 or 2.3 mm.

Asus mg279q
Hi i have a problem with this monitor mainboard.
I found a missing resistor on PCB; R261.
Maybe a wrong board manipulation and R261 was torn from pcb.
Can you kindly tell me the value of this component?
TIA

MB FPC70 LA-H472P rev 1
Hi
i have this MB (from a Pavilion 17-cd0600ng) with some problems; laptop had a small liquid damage.
I dried the MB and laptop worked some months after the damage, but now it has frequent blue screens.
Opened laptop and found some components with corrosion signs (2 resistors and 3 capacitors). Under the microscope i found that resistors are definitely damaged.
So: i'd like to have schematics (or, better, boardview) to find damaged components value.
TIA
