Hey guys, I have a Lenovo Ideapad 320-15ikb NM-B241 rev:1.0.
After turning it on, it runs for a few seconds then shuts off completely. No screen, no fan. After shutdown, a red light comes on and off fast. I've been trying to troubleshoot this for days now. It's never been opened up; the Lenovo sticker is still intact.
(!)I tried with a different BIOS battery, without any ribbon cables, on battery power, without the keyboard, and it's always the same.
Any insights on what might be causing this?...

by E--ManHi All,
Thanks for reading. Based on the interesting fact that the vertical lines issue don't seem to effect the menus whatsoever but rather everything around the menu regardless of video is shown, I'm trying to set mine whether the issue is the main board or the t-con board.
Again what's baffling is that the menu is not effected whatsoever. However, any other video displayed regardless of inputs or when no inputs exist exhibits the vertical lines and seem to effect black areas only.
The lines are green in color when the tv is in "Game Mode" and...5 Photos05-12-2024, 10:52 AM -
by copeHi everyone,
I have been working on a no power issue with my personal ASUS gaming laptop. It went dead a few months ago.
Some history:
Since then, I've found a blown mosfet on the GPU line which I replaced. It started up without a battery, then when I added the battery back it wouldn't start up again.
As a result, there were some blown components around the BQ chip. (The BQ chip itself - BQ24780S, the low side battery mosfet (shorted), and a resistor -> all replaced)
Now, with a new battery the system will start up and run off...Yesterday, 09:40 AM -

by tuankietkietWhen plugged in (no battery installed), the battery light on the motherboard lights up and then turn off. When powering on, the same and light and the power button also light up in a white color but no output on the display. It stayed like that for a few seconds before shutting down. I also seem to ruined a connector that connects to the WLAN, 2 USB and audio board, the same board also have a melted 2062A IC. I will post pictures in the reply section05-11-2024, 04:40 AM

by RunlincHi everyone, the tv was in a continuous reboot cycle. To get the best screen image i can I taped the VGH and VSS pins on the left side buffer board joining ribbon.
I am left with a good image apart from the black horizontal lines that I cannot get rid of.
I cannot find anything on the buffer boards that has shorted.
Do you think there is anything i can do to eliminate the lines, or are they caused by an internal panel short and the image cannot be impoved.

by fharris1977I have a MacBook Pro Touchbar A1706 that won't turn on. With the board removed I'm getting 19.62V and an average amp draw of 0.300A. When I first plug in my ampmeter it goes from 5V to 19.62V after a second or 2 and the amp draw starts at about 0.688A and up to about 0.790A and then it gradually goes down to about 0.155A and works it way up to around 0.330A and then it fluctuates in the range of about 0.200A-0.350A. The voltage stays at 19.62V. Can someone with any experience with this issue help me out. I checked all the main power rails and they were present. Anyone know it would be greatly...Yesterday, 12:39 PM

by RomanSko1Hello, gentlmen!!!
My HP Probook 430 g2 does not detect battery. I tested the battery on another laptop and it is OK.
I believe smth is wrong with my PC ((.
Searching this forum I found some nice suggestions.
So, I tested Battery Connector pins (charger in/battery out) and here are my results:
pin_1 0v (-)
pin_2 3.30v
pin_3 0v
pin_4 3.38v (SCL)
[B]pin_5 2.55v (SDA)!!![/B]
pin_6 2.25 (+)
As far as I understand SDA pin must be ~3.3v???
Are there any other tests I can do before disassembling motherboard?
