Hi everyone, Dell inspiron Duo PIM00 LA-6471P.19v only on power connector and 17v on power switch. No 3.3v or 5v.I do not have schematic so it is very difficult trying to trace power lines. Any help will be appreciated.

Re: DELL INSPIRON DUO: No power, 17volts on power switch.
Well it turned out that upon closer scrutiny, PD22 was missing [don't know how] and PU10 and PQ18 was shorted so laptop works fine now and power switch voltage gracefully dropped to 3.2v. :mrgreen: -

Hi Siddiq. Would you remember how you fixed the short. I seem to have the same problem with a laptop my friend brought me. Thanks. [IMG]

Hi everyone, I have an Inspiron 7506 laptop I've had for a few years, and it'd occasionally have a problem where after I'd power it off, it wouldn't turn on again unless I disconnected, drained residual voltage by pressing the power button, and reconnected the battery. It now seems to be occurring every single time I shut down the laptop and attempt to turn it back on again. I have done all the common troubleshooting steps, such as completely disconnecting the battery & CMOS battery and draining the voltage and leaving it for an hour, and I've even replaced the battery. This is definitely...10-17-2025, 05:33 PM -
Hi Everyone. First official post so fingers crossed I conform and also manage to get photos to work.
So I am requesting some help from anyone who happens to have one of these motherboards to hand and perhaps a multimeter.
My board has a single row of header pins for all the front panel stuff (have seen others where they are grouped together differently so thats no help) and the two pins for the power on switch had been previously repaired and I am trying to make a better repair. There looks to be pad and trace damage and im happy to relocate the header pin/pins to...06-24-2024, 01:24 PM -

Ill try and give as much info as I can.
Dell Inspiron 17 (7786) Laptop
Service Tag: 5J0NHT2
Bios: 1.9.0
When I received this , it would only flicker on the KB backlight for a second, then off and on.
Then it started getting weirder!
Sometimes when attaching the AC power supply, and pressing various pre-boot diagnostic keyboard keys... it did try to boot, in fact out of a hundred attempts, the laptop did actually boot into the Bios ! but never has... -
Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?I was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.
Upon bringing it home and plugging it up, it showed a standby light.
I powered it on and without a flashlight, the display showed the "V" but the lighting is very dim, but visible.
The screen seems to blackout and stay black, but with a flashlight I can see the display.
With my Playstation 4 connected via HDMI, and running a game I can hear sound.

Hi everyone,
I have a Dell Inspiron 15 3511 that stopped turning on after my friend plugged in the power adapter.
Here’s what I’ve checked so far:
No reaction when pressing the power button (no LEDs, no fan).
The power adapter works fine (tested).
One chip gets extremely hot as soon as I plug in the charger.
The capacitors around that area are not shorted.
I’m attaching photos of the board to show the issue.
Based on this, what kind of fault or defective component could be related to this overheating?...
