MS-17E71 VER: 1.0 EC and BIOS dump needed (MSI GL75 LEOPARD 10SFR Laptop)
Looking for an EC dump for MSI MS-17E71 mainboard (KB9028Q EC chip)
It is in MSI GL75 LEOPARD 10SFR laptop.
BIOS dump might also come in handy.
Thanks! -

Does anyone have a different dump I can try?Leave a comment:

Same thing. Tried it without the HDD installed...Leave a comment:

Need a HP 255 G8 (HPL51 LA-L021P) BIOS
Looking for a BIOS for HP 255 G8 (HPL51 LA-L021P).
The main problem is that the laptop will crash while booting to OS. Will crash even on booting from USB, like a Ubuntu or to a Windows 11 installer.
Before junking the board I would try the new BIOS if it does anything.
Thank you!... -
Anyways, I marked all the pots with sharpie and started turning them slightly. The one marked 3537 is clearly the G2 voltage control as I was able to crank it up so the retrace lines started to show up. This is the third one from the rear side...
Now the image is much brighter, and still very sharp. So most likely the tube is in a pretty good condition stillLeave a comment:

Vintage Philips 4BM2797 CRT BW monitor repair/tuneup
I have a Philips 4BM2797 black and white VGA CRT monitor that is very dim. If I put the brightness at medium (indent at the pot), the text is barely visible in a moderately lit room.
I looked around for a service manual, but was unable to find one. Also there are no G2/Focus adjustments on flyback...
There is a row of adjustment trimmers, but they aren't marked..
Anyone has any info about it?
Thanks... -
Anyways, I replaced the U3200 (the most likely suspect) and the board is working now

Here you go:
PP1V1_UPC_XA_LDO_BMC: 0.550V
PP1V1_UPC_XB_LDO_BMC: 0.550V
PP1V8_UPC_XA_LDOD: 0.512V
PP1V8_UPC_XB_LDOD: 0.511V
PP1V8_UPC_XA_LDOA: 0.554V
PP1V8_UPC_XB_LDOA: 0.553V
PP3V3_UPC_XA_LDO: 0.525V
PP3V3_UPC_XB_LDO 0.525V
Both read exactly the same...
... on the logi.wiki it says: PP1V1_UPC_XB_LDO_BMC (On active port after reading TBT ROM). So that means if I get a 0.98V on inactive port, and 1.1V on active, that the inactive is dead? Connected other way around, I do get 1.1V on active and...Last edited by mitchw; 01-09-2024, 08:34 PM.Leave a comment:

I did rotate themLeave a comment:

Both measure the same.
Found next (possible problems):
- PPBUS_G3H is 12.3V (should be 12.6V I think)
- PP3V3_G3H is 3.3V
- PP5V_G3S is 0V
- PP1V8_G3S is 0V
No shorts on those two, which makes sense as the laptop worked fine on battery when booted to OS install after DFU.
On battery of course there are all voltages present...
I also did another quick check of the LDOs of the CD3215s.
All of them are fine, except there is a bit strange behavior of the PP1V1_UPC_XA_LDO_BMC and PP1V1_UPC_XB_LDO_BMC voltages:
If the charger...Last edited by mitchw; 01-04-2024, 06:41 PM.Leave a comment:

I'll check it out, thanks.
Anyways, if I have battery connected, it gets to 20V, but stays at 0mA.
With battery disconnected, it only gets 5V, but draws 230-240mA.Leave a comment:

MacBook Air 2018 A1932 820-01521 stuck at 5V, but succesfully does the DFU and boots into OS installer
I have a 820-01521 that is stuck at 5V, and drawing just 230mA.
I did some troubleshooting, and managed to charge the battery up (was at 0%) using a different logic board.
Also I ran DFU and it did it successfully. Had to use a PMU_FORCE_DFU jumper to do it.
At this point the laptop started up and it successfully boots into the OS Install.
The charger is now at 20V, but drawing 0mA, so the laptop is essentially running off the battery. It doesn't detect the charger...
I think there could be a problem with one of the CD3215s, but all the LDOs are the... -
I am also looking for schematics for DABKLMB28A0 (for GL703V)Leave a comment:

Re: M1 MacBook Air 820-02016 possible to swap ROMs to unlock a locked board?
I took the battery out and on the bottom side of the battery PCB there was some corrosion.
One resistor was particularly corroded, and it later fell of when I tried to measure it. It read OL even after off the board.
I guess there isn't much to save with this battery. Or if someone has the value of the resistor and I can resolder it back......Leave a comment:

Re: M1 MacBook Air 820-02016 possible to swap ROMs to unlock a locked board?
Oh ok, didnt know about this, despite having a 16 inch M1 MacBook for a year now.
I managed to restore it now. The battery says “Service now”. So I guess battery is itself bad..?...Leave a comment:
