[FONT=Lato][COLOR=#141618]Hi, I have a Toshiba Satellite L50 here and its not powering up.[/COLOR][/FONT]
[FONT=Lato][COLOR=#141618]Bought from guy who has no need of bricked laptop
It would give a Power LED and a Charge LED but press the power on button and nothing not even a fan noise or anything.
Tried removing all hardware still nothing
Left the battery on charge all day, the next day it was only reading 3 volts.
Removed battery and still not even a power or charge indicator.
Mains charger giving 19 volt

hello. I knocked off a capacitor on the apu (probably while cleaning off the thermal paste i guess). I have done some google search and i got 2 answers so I'm confused ( 1uf 0201 and 0.1uf (100nf) 0201). i think the ones above the missing are same value but i am afraid to remove it and check due to the tiny size, fear of losing that also; and also maybe scratching or damaging the apu. Anybody has actually measured these caps please help.Today, 08:19 PM

Most Displays I have worked with are of course LCD Or Blueish Fluorescent Types. I Have a Marantz PMD800 tuner with sort of a white display. The display area is a sealed rectangular shape in a Glass Case. Looks like some sort L.E.D. display only not your typical section number type. I picked up this Tuner cheap as the display is very Dim. In front of the circuit is a dull red Plastic lens.
The display is very week and hard to see. I've got my DC 5 Volts allover and also a DC 32 Volt that runs some other section. Power supply looks good front to back. Not familiar with this type...06-07-2024, 07:19 PM -
Yes you don't need to grill me im already the blah blah blah. But anyway...
I was wondering around inside my unlocked advanced bios reading about every little setting and trying to understanding and just learn in general. I changed a few things which I thought would be beneficial.
I've gone to restart my laptop and the recent state was power on, keyboard lights, no display black screen assumed bricked bios. Using all the general methods of recovery remove cmos short capacitor remove battery, ram, ssd all deemed unsuccessful.
With more research and semi knowing what I did...Today, 03:39 PM -
This started a few days ago and does this about every 8 hours
After it does this it goes back to normal no bad battery icon and no weird sounds and it goes to battery backup mode so I am not sure what is going on with this battery backup
The battery backup is about 3 or 4 years old
Dose anyone have any idea on how to troubleshoot this issue I have never had a battery backup do this kind-a thing before so I am not sure exactly how to troubleshoot it and where to start06-02-2024, 02:30 AM -
I found two capacitors on the board and one of the leads on one capacitor had bad soldering joint and the other joint connections not much better and there were several soldering joints that way to much flux around the joint redid several of them
The capacitors were a non brand that I did not recognize they got replaced and now it does not oscillating between relay but what concerns me a little bit is when the voltage is a little bit low the output voltage is around 130 volts and then drops down to 115 volts this happens around 105 to 108 volts if remember correctly
Now...Yesterday, 10:57 AM -
Hi again guys. I have this motherboard that won't show display even tho it was doing it yesterday. I think something could've past away in the circuit.
I'd appreciate if anyone who is used to MOBO LCD voltages and circuits could enlighten me since this is the first time I have to deal with it.
I'm missing [B]+3VLCD.[/B]
This is the circuit

hi again
this time its a mainboard from a mowerrobot, when i connect battery it shorts it, so the bms shuts down battery.
when take the mm in beepmode and measure from the positive to the negative battery terminal on the board it beeps shortly like 0,25 sec, and when i reverse the probes it beeps again shortly 0,25 sec.
when i mesure on the cap thats missing in pic nr 2, the bottom solderpath goes to the negative, the upper one is 1,2 ohm to negative is this a short?
hope Capleaker is still around05-27-2024, 02:33 PM
