Lenovo V14-IILWont Only post with OnBoard RAM
Hi all, need some help, I've got a Lenovo V14-IIL that as total of 8GB of RAM (4GB onBoard - 4GB Sloted), out of the blue it stopped posting, After investigating, found out that removing the RAM stick from the slot, the laptop would post and work with no other issues. So tried with a different RAM stick suspecting that the original one somehow died, but to my frustration the issue remained, so again tried a different number of known working RAM sticks with different capacities and speeds but with no avail.... Unplugged Battery, removed CMOS battery,Reset and Updated Bios, also measured voltages...

Lenovo IdeaPad 100-15IBD Freezes when loading Windows
Hi all, I have a Lenovo IdeaPad 100-15IBD, motherboard NM-A681 Rev1.0 that posts normally, all voltages ok, but when its starts to load Windows after a few seconds the spinning dots just freezes. Unplugged everything unecessary from the board, tryied different ram sticks with no avail. Tried also just booting from the usb stick and the issue persists. There's also an option in Bios to use Intel's UMA only, turned off secure boot also, and nothing...
Please advice, thinking to ask Bios guru's to clean ME region, just to make sure it's not related
Thank you in advance

Asus X551MA-SX051H Turns on and after 5 seconds turns off
Hi guys, need some help trying to figure out what is happening in this Asus X551MA-SX051H - Board X551MA Rev 2.0
So when pressing the power button power light comes on and after 5 seconds goes off, no shorts found on the board, 19v, 3.3v (at SIO) and 5v present. Measuring bios chip at pin 8 (25Q64FWSIG - 1,8V) there's nothing there but here's the funny part if I remove the ram stick and press power button the board turns on and stays on, now all voltages are present and the cpu is getting warm. Tried different ram sticks but no change.

Asus X552EA-SX091H Not powering up
Hello all, I have an Asus X552EA-SX091H, with mainboard X550EP Rev 2.0 that will not power up.
Here's what I've checked so far. 19v is present after the first 2 mosfets and current sense resistor, there's 3,3V present in power button and when depressed goes to zero, but nothing happens, Bios chip as no voltage at pin 8 (3v)?.
Checked all inductors and there's not short to ground
At PJ8102 near the buck converter mosfets there's is 19v coming in but nothing coming out of the inductors which should be the 3v and 5v alwais on.

MacBook Pro A2159 display issues
Hello all, I need some input regarding the flickering / wierd lines / color distortion in the display that these models eventually will suffer from. I've got my hands on a brand new display, and the problem still persists though it doesn't manifests so bad compared to the original one.
I'm guessing that the LVDS cable is also bad, which is a litthe bit wierd because there shouldn't be any movement on this one.
Does anyone had a similar problem that replacing the LVDS cable solved the issue?
Best regards

Samsung NP370E4K No backlight running on battery
Hi all, need some help. I have a Samsung NP370E4K-KD2BR, which as a 5th Gen Intel CPU that works fine when running with the charger plugged in, but has soon as I remove it and it's running on battery the screen backlight goes off.
Tried different battery - no change
Tried different screen - no change
Removed the plastic film from the screen inverter and looked for pwm signal which as about 3.3v when running with the charger plugged in, when I take it off the voltage drops down to 2.232v, so my best guess is that the EC is not providing the correct voltage....

Re: Asus X512F won't hold on battery charge
Hi all, final update on this one, and when you thought you've seen it all, something new will prove you wrong. So yesterday I had a costumer that brought an Asus laptop for a screen replacement, while working on it saw that the battery pack, although different in shape had the same connector and rating, so I thought, why not? let me try this one.
So I plugged it in and pressed the power button, the power led came on, and after a few seconds it started flashing white along with the battery led, nothing came up on screen, turned it...

HP 15S-fq2006np all voltages present but wont boot up
Hi there, I have an hp 15S-fq2006np that had some liquid damage. After cleaning and replaced some resistors and capacitors, the laptop returned to life.
Worked fine. Fresh Thermal paste, ran some stress tests. Prime95 ran for 6 hours straight. Everything seemed ok.
After a couple of hours costumer was playing a game and suddendly the screen went off. Now pressing power button, the power light comes on, all voltages are present but no fan spin, and nothing on screen
CPU doesn't get warm. Changed ram sticks also, but still the same.
Could it be a messed bios? He said...Last edited by Kambi13; 05-22-2023, 12:54 PM.
