maybe i am not seeing good but on the first picture that gpu ram seems blown? also right of that ram i can see mosfet also burned? But maybe its just bad picture...but it is cleary someone worked on that area because there is discoloration and you can see cooper in that area.

So, i have a HP LAPTOP that needs central pin of the specific voltage to be recognized by ite chip as original and correct wattage. My laptop needs around 19v volt and 7 a charger (135 W) and i attached from the schematic Adapter select for EC. The thing is i have only 200 w HP adapter. When i connect it the power led is not showing any light and output on AD_ID 0,56 V. According to the schematic if i replace resistor R5115 17,8k with 100 k resistor, will my laptop work? is that only thing i have to do to be able to power it on with my higher watt adapter?
thx

It could be gpu or something else.. First check if it is gpu.... when laptop is stuck at the logo try caps lock on/off...if lights turns on/off then your laptop is ok but gpu is dead. If you can not turn it on/off then something else is wrong and it will be very difficult to find, because when loading windows the windows will stuck for many reasons, maybe not working memory, try checking memory connectors on the board, semi dead pch, cpu, or any of the chip on the board...very hard to find.

Here it is, you should have 19 v on both side, and that fuse has to be shorted (between pins 0 ohms)

ok, thx and what about that mosfet?

First, i dont work on monitors only on laptops and that also for a hobby. So, i received this monitor in the title and it was completely dead, and power supply when used was going off to a power protection. I found that one of the voltage regulators for backlight GS9238 is dead, so i replaced it and monitor is working fine now. But...on the main motherboard first thing i tested was a main power rail and after power jack there is one mosfet Nikos PD537BA. The thing is when i tested all pins of that mosfet are shorted in between. Now when i plug the adapter the monitor just goes on. I dont think...

This Lenovo laptop is like new, used once and then was not used for three years. Laptop is working fine but the battery is not charging. When i measure with multimeter while charger plugged in, the voltage on battery connector jumps to 15 vol to 0,8 vol, then again 15 vol to 0,8 and so on. Left it over night but same thing. When battery removed it shows 0.00 vol on battery. I was thinking to use lab power supply to try to revive it but i must say that i have a little experience with fixing batteries and that i never tried to charge this long dead battery that shows 0.00 vol. I thought i once...

Looping is fine if you removed bios battery, the system is trying to read the bios and adjust some seetings, and that probably means that cpu is ok also. I dont know if this model has integrated gpu. Try this, after laptop makes several boots try pressing caps lock key on keyboard...if you see light goes on and off then your cpu is fine and you have a problem on gpu area.

Re: how to remove black glue in edges of chips in Lenovo laptops?

That is the exact reason why I also don't work with lenovo boards, either fixing them or using them for donors. If someone do know how to remove it he probably enjoying and keeps it to himself...There are some videos on youtube claiming they done it..but it seems fake.

asus gl504gm clean ME

Can someone please clean ME region of this bios attached. thx

Serial number is J6NRCV00H419269

The problem with this laptop was dead pch. I replaced it but had two problems ..first, on startup the screen would turn on after 10 seconds and when try to shutt it down it would hang on shutting down but would not shutt it down( restart was ok). Now i used that bios with cleaned ME and copied my bios data with hex editor ....and now laptop is shutting down without problems but when powering on laptop i still have to wait like 8 seconds to...

Re: OMEN LA-H482P not passing after bios

You were right...the problem was exactly ram slot. Thx

i dont like semi working laptops because it is very hard to find a fault.
This laptop is working in bios with no problems regarding graphic card there is no flickering and so on. But when i insert installed nvme disk or usb stick with windows installation it just freezes on apple logo and that white circle. So, i was thinking its probably gpu but...i also noticed that when it freezes it stays one and the caps lock light is not turning on/offf anymore...I could turn it on/off in bios or on startup but not any more. So it seems it is not posting after trying windows load...but that means...

Please CLEAN ME on this bios. Its from asus g752vsk i7-7 gen. thx...

I received several dead laptops with nvme disks showing in the bios that are ATA locked. Is there any way to format and use those disks or they are just trash? Thx

I have Alienware m15 R2 Compal EDQ51 LA-H351P with one of those connectors to a usb/power bords damaged behind repair (many pins missing...)
I was looking on ebay and Ali and they are very expensive but i found that dell precision 7530.7540.... laptops have maybe the same connector but i am not sure...So anyone tried this replacement before?

First link is to a connector original for alienware and second link is from dell precision laptops.

Re: Asus GL553VD, need expert advice !!!

I dont know why you played with BQ24735RGRR chip and power main mosfets...because according to measurements from your first picture the BQ chip and mosfets are working fine and you have 19.7 volts on +AC_BAT_SYS main power rail. So, your problem, why motherboard is not turning on is somewhere else.
And now, because you have lights, ite chip is probably fine. Check pch chip and every coil on the board...if there is no short, maybe its bios issue. And please keep in mind that short on cpu and gpu coils are only if resistance is lower...
