DELL Alienware x16 r1 bios dump or clearME
Hello friends,
Alienware X16 R1
MB: IDP60 LA-M418P Rev1.0 (A00)
ST: 4MH6RV3
black screen, power led swapping colors, then blinks 4 times blue and turns off
I attach the original bios and a modified version with System BIOS replaced from the latest official file. (it seems the original bios is 1.14)
I need to clear ME for both. Found the MFIT and the required ME firmware version but i'm not experienced with version 16.1.
Thank you... -
Here i am too. PPVCC_S0_CPU to GND 0 ohm.1V injection while the phases coils are removed drops to 0.75V @ 5A. There is a thermal production on or around CPU but i can't say that the CPU becomes hot. tbh nothing that is connected to PPVCC_S0_CPU becomes hot. Even after 5 minutes of 1V injection. any idea? Device had only a small spot of corrosion on R7673 and C7673 just next to U7650.Last edited by incorrect; 11-25-2023, 03:33 AM.Leave a comment:

Re: HP LA-D711P no power after not charging
update.
while i plug the charger i see a spike of 0.5v on the gate of the first mosfet.
seems like somethings turns the gate off.Leave a comment:

Re: HP LA-D711P no power after not charging
ACDRV and CMSRC still 0V.
I removed the 2nd mosfet and shorted source with drain. ACDRV and CMSRC went to 0.8V.
Also, i found that BATDRV is 1.5V. not sure if it's normal...Leave a comment:

Re: HP LA-D711P no power after not charging
I took a look to the bq datasheet yesterday already. I believe that the ic needs replacement, because of the shorted pq4 earlier.i will replace it as soon i receive a new ic and i will keep you up to date.
@mon2 the voltage on vcc seems normal.Leave a comment:

HP LA-D711P no power after not charging
Hello,
my LA-D711P stop working. found and replaced a failed ceramic at 3VALW.
after that, battery couldn't charge but laptop could turn on.
found that PQ4 was shorted. I replaced the PQ4 but no voltage on gate.
Any idea will be welcome.
Thank you -
Re: Surface pro 4 backlight issue
Back to my own post, i just removed the MP3388S and the voltage on Vin came back to 8.5V. So it seems that the Driver ic failed. Waiting for the new one to replace it.Leave a comment:

Surface pro 4 backlight issue
Hello all,
a dead surface pro 4 arrived at my place some days ago.
It had a blown fuse (0ohm Resistor) and i replaced it.
After resistor replacement, i connected the display and checked the device and the device turned on. i just unplugged the power at surface logo and assembled the device back.
After that, i turned on the device again but no backlight at all. The LED Driver IC - MP3388s Vin is 0.35v before power on and 1.5v after turn on but still not enough to turn on the LEDs i think, as the driver ic needs 4.5V+. I see some spikes from 1.5V to 4V some times but... -
Re: ISL95833 +VCC_CORE ok, But no +VCC_GFXCORE_AXG.
Back to this post. I have the same issue. No +VCC_GFXCORE_AXG. No UGATEG signal too. everything else is working fine, or i think so. I didn't replace ISL yet. Already tried 3 bios dumps. The device starts with 5 beeps but of course no display. it is UMA. Any suggestions?Leave a comment:

Re: gl702vm 6th gen for service - No Post
yes,it is the one with the 1060 6gb gpu.
thank you very much for the info you shared.
i believe that if the problem begins from the vram block, the laptop should stay on while no voltage on vram block rails.no?
i would probably cut the power on gpu rail and check if the laptop stays on.Leave a comment:

gl702vm 6th gen for service - No Post
greetings all,
i have a gl702vm 6th gen for service.
the laptop turns off after 3-4 secs.it doesn't even post.
i tried some bios dumps but the problem persists.
the cpu insta overheat but the gpu stays cool.
i think the laptop turns off because off the cpu insta overheat.
1.06v on cpu is ok btw.
any ideas are welcomeLast edited by incorrect; 05-20-2020, 03:16 AM.
