Hi, I have this laptop, it is completely dead, no charging light when connected to a working charger.
Can anyone help me with some hints for troubleshooting this laptop?
Thanks in advance...05-07-2024, 05:28 AM -
I bought a T12-958 recently with an M8 handle and until now it has worked very well. The tip wasn't earthed but that was easily resolved.
Now, whenever it is switched on, it heats up to about 70*C then shows an [INVER] error on the screen and stops. In order to fix it I have to either unplug and re-plug the handle, or unplug and re-insert the tip from the handle. While doing that it changes to [ERROR], then it finishes heating up and works perfectly. Until it's turned off, after which it will show [INVER] again next time it is turned on.
Any idea what the problem is?05-06-2024, 01:36 PM -

Hi guys,
i want to challenge myself to fix this graphics card- I know it's low value :-)
01g-p3-1313-kr (GeForce 210)
found 1 blown fusible resistor R56 ( already removed)
1 shorted diode D5 (already removed)
and i suspect short on U2 (ic itself isn't shorted)
i would like to know substitute diode and look at the diagram of that circuit....Today, 08:00 AM -
My laptop is black screen, but have power. HP 14s-cf0121TU.
LED status - 3 long 2 short.
Already replaced with new Ram. Same frequency. But same problem.
Any other solution? I'll just test the bios if corrupted. Thanks.Today, 06:06 AM -
Hi, I have some capacitors that I need to replace on a graphics card.
I've attached pictures for reference.
Please help me to understand the ratings so that I can order the correct replacements:
[B]1. G7 560 2.5E - I believe these are for vcore[/B][LIST][*]Is this 560uF and 2.5V?[*]What does the "E" mean?[*]Is there any relevance to the "G7"[/LIST]
[B]2. ECX 17 560 2.5V - I believe these are on the memory phase[/B][LIST][*]Another 560uF at 2.5V?[*]This is on the same graphics card. If the caps are rated the same as those above, why...Today, 07:56 AM -

Hi
I have a 453 Mini , two of the four Sata ports are not getting 12V . I am wondering if anyone has knowledge on hardware repair on these devices . I have attached an image of the board , it appears the Sata ports are powered in pairs , the right pair are working , left pair no voltage ( 0.2V)
I have tried tracing the 12V rail , though have not been successful . I am guessing there is a Transistor or Mosfet that is open
Any help , perhaps a schematic?
The board otherwise appears to work fine .. Boots up ,

I have an Asus G14 (GA401QM) that has a power issue. Originally the board had a shorted 5V rail and dead EC. I reballed a working EC, soldered it on, and I resolved the 5V issue by replacing the APL6012 and the low side 5V mosfet. Resistances on all power rails are healthy now, but 20V does not make it through the first MOSFET. 20V is present on the drain of the first MOSFET, but there is no voltage on the gate or source.
When diagnosing this issue, I thought that the issue was due to the BQ24800 chip not outputting the correct signals so I soldered on a known working chip and the...05-08-2024, 01:30 PM -

Hi,
working on a ASUS ROG STRIX GL702VSK 60NB0DZ0-MB1260 that does not power on. At the PQ8900 PIN2 (P_CHG_ACMOS_G_20) I am receiving 24.7V and PIN1 (P_CHG_ACMOS_S_20) 20V, however when I place the PQ8901 P_CHG_ACMOS_G_20 it drops 0V. I don't have the replacement mosfets ( N-MOSFET QM3058M6AC PRPAK5*6
UBIQ) however will any N-channel mosfet with similar parameters work ? I also found that PCI8703, PCI8701 are shorted. any help would be grateful.05-07-2024, 04:34 PM -
