Re: hp g62 010170100-600-g power on and immediatly power off
Hello there, you should reprogram the bios chip 1st, cause it is a common fault on these kinds of laptops. That being said there is a chance that the machine is in a protected state due to overheating and the north bridge might as well be fried.
And try to be sure of the Charger you are using, it has to be an hp 90W psu, the smart pin thing is a real pain in the ***. -

I thought it was bios but in the forum I did not find any dump, do you have one? when this happened the pc issued a distorted sound and got stuck, when then I restarted it did this phenomenonComment

Yes, nothing chip or component are hot, the laptop power on and off continually when the problem appeared the handset was running properly, I unplugged the power cord, the battery was plugged in and the screen disinked and the buzzer sounded very loud. when I turned off the laptop and restarted it started to do this. Help :-(Comment

it does not seem a Bios issue. it is probably something like a power problem. but I am not sure. the only way is to check mainboard components according to schematics. first check the AC adapter as recommended in post 2.Comment

Hi friends I have measure at coil pin and measure 0V if I take positive from dc jack and negative on coil I measure 19V at laptop switch off and 16,22V on one coil and 14,2 on second coil at laptop switch onLast edited by magnetepazzo; 11-23-2017, 03:02 PM.Comment

I do not know about this method of measurement.
standard method: put black probe on GND and red probe on the point which you want to measure.
If you do this measurement, important faults may be discovered.
Assuming you measured correctly, 16,22v and 14,2v are bad voltages.
please report like this: L1021 = 16v.Last edited by caspian; 11-23-2017, 04:01 PM.Comment

if you have pulse on one side, measure on the other side. Thats normal. All bigger coils are part of switching power mode power supply. Try the board without RAM. Then if the board not switch off immediately, try it with other memory modul.Comment

Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?by Tynan DillI 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.

by PantherDaveHi all!
I'm trying to troubleshoot a Microsoft Surface Pro (5th gen) model 1796 that won't power on. Motherboard model is M1007506-015. My priority is retrieving data, but the SSD is integrated so it looks like if I can't repair it it'll need to go to a data recovery company. I've done a little basic board repair before, but nothing this advanced until now. So please forgive my ignorance in advance. 😅
I found the boardview for this laptop in the forums here, and am able to open it on my PC with FlexBV.

by GLISITHi all,
TL;DR - this laptop is driving me nuts with the oddball power-related behaviors. Appreciate any insight you can provide!

by sam_sam_samI have wanting to do this project for quite sometime now and I finally found a switching power supply that will work on this desoldering gun station ZD-915 that the original switching power supply took a shit and just was not worth trying to fix it because this switching power is not quite big enough to handle the heater element and the vacuum pump
One note when I tested the switching power supply and the voltage control board I noticed that this desoldering gun heat up much faster than the original switching power supply which I was really surprised by to the point that I might buy... -
