Clevo N150SD powers on for 10 secs

Re: Clevo N150SD powers on for 10 secs

The ME,or Management Engine is a part of the bios that often gets corrupt. Your bios is split across 2 chips,sometimes the bios is just on 1. The clevo bios you downloaded has 2 bios files,1 is the 4MB bios the other is the full size 6MB bios.That 6MB bios has to be split into 2 seperate files using a hex editor to get the 2MB bios. Your bios backup has the new 4MB bios so just flash the attatched 2MB bios and verify its flashed ok. If it boots its fixed ,if not its back to testing .

Re: Clevo N150SD powers on for 10 secs

I flashed your U18 NEW to U18 with no difference.

For U17 I opened N150SD.01 from the downloaded bios and flashed it to U17, is that correct? If not, could you send me the correct bin file for U17?

Re: Clevo N150SD powers on for 10 secs

N150SD.01 is the right one for 17 .As you`ve flashed a good bios now to U17 and U18 you can rule out the bios being a problem,the other members will tell you what to test next .

Re: Clevo N150SD powers on for 10 secs

After opening N150SD.01 in the program it would show this message, after clicking ok it showed up in the hex side looking the same as my dump, is that all good?

Re: Clevo N150SD powers on for 10 secs

I opened N150SD.01 with my CH341A software and got the same message,closed the software opened again and the error message was gone. If you read the bios and compare it with the file N150SD.01 they should both be exactly the same,just to double check that verifying after programming worked. Use a hex editor to compare the 2 files or a hashing tool,such as hashcalc (ok on win 7) https://www.slavasoft.com/hashcalc/

Ok great, it should be all good, thank you. :-)

Re: Clevo N150SD powers on for 10 secs

Stated in the first post CPU Vcore is 1.69V, PL1 & PL2 coils, isn't 1.69V rather high for Vcore?

[piernov]

Re: Clevo N150SD powers on for 10 secs

1.7V on VCore is perfectly fine for Haswell.

Ah good :-)

Where do you think I should start next?

Re: Clevo N150SD powers on for 10 secs

check PL8 1.5VS
all pins of U10 excepte 15 & 11
check PQ35/36 D1 D1 for 19V in

For U10
pin 3 dGPU PWR EN pull up from R157
pin 5 3V3 MAIN EN come from U7 BGA

PU4 pin 3 EN missing that why PL9 PL10 no out put
test PQ9 gate ?
may be it's BIOS or BAD BGA some one else can help ?

Re: Clevo N150SD powers on for 10 secs

I'm not sure where we are at.
Does it have PLTRST#?
Was a known good BIOS tried?
Does it have activity on BIOS CS# pin?
Does it seem to POST?

U17 CS# pin1? 3.2V

Here is a video of what it does: https://youtu.be/BGkaSCkJktk
Power LED goes from orange to white
CPU on the left, no fan spin
GPU on the right, short fan spin (heatsink currently off, stays cold)
Stays on for roughly 15 seconds before turning off, orange light.
There is no video out on display.

What should I do next?

Re: Clevo N150SD powers on for 10 secs

Guys what will happen if he remove Q9 R157 bypass dGPU PWR EN to R158 to Enable to output 3.3V AON at page 73 3.3V AON become 3V3_main_EN with a 10K Resister ???

1.7V on VCore is perfectly fine for Haswell.

You mean the input or similar? Because the last Intel processor rated at 1.7V Vcore, was a Pentium III, LOL.

Looks like the processor will get damaged.

Re: Clevo N150SD powers on for 10 secs

Bump.

Re: Clevo N150SD powers on for 10 secs

You are using a known good DDR3L RAM stick right?

If it still has VCore but is not POSTing, you can probe BIOS CS# pin with the oscilloscope and LPC bus too (on LFRAME#) to see if there's any activity but it won't help much anyway. It can be almost anything, EC, PCH, CPU, maybe GPU, random stuff going on somewhere…

I'd try another known good BIOS.
