Re: Presario CQ62 won't power on
Please explain more details on Laptop behavior after plugging in and also after pressing the power button.
Any LED on or blinking?
In addition, explain the voltage measurements you did so far.Last edited by caspian; 03-20-2016, 03:19 PM.Comment

Re: Presario CQ62 won't power on
We dont know, what model exactly you have as well. As we dont know, if it is AMD or Intel one, some schematic attachement would help.Comment

Re: Presario CQ62 won't power on
This is a CQ62-423NR, product # XZ199UA#ABA. I hope that is enough to identify processor type, etc. I bought a new power adapter to eliminate a bad adapter as the problem. There are no lights when plugging it in. Do I need to open it up and take pictures? As for reflashing, I don't know how to do that. I haven't made voltage measurements, I need direction on where to measure.
ThanksComment

Re: Presario CQ62 won't power on
Agree with Passete, flashing BIOS would help.
You need external SPI programmer. There are some topics here how to do that so use searching.Comment

Re: Presario CQ62 won't power on
dnixon , not much , 80% thats its bios problems , very hard doing it via crisis rec , so you will need to open it and flash bios
you will need a rom programmer , if you don't have any , try to find any local store that can program it for you , or in last case , buying a programed rom for this modelComment

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 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.

Hi all,
TL;DR - this laptop is driving me nuts with the oddball power-related behaviors. Appreciate any insight you can provide!
I'm experiencing a power issue on an Asus Probook P5440UF-XB74. Although I've worked with electronics and computers for decades, this is my first attempt at getting into motherboard-level component troubleshooting. Any help the community can provide is greatly appreciated!
A few weeks ago I was using the laptop (on battery power) for a Zoom meeting. The battery was running very low (long meeting) but I wasn't worried about... -
I 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... -
