Re: Lenovo L430 won't turn on
I said something wrong about the measures I had done.
I measured all voltage with the charger plugged without battery (dead). What I wanted to say is for Pl4301,pl4302, PL4601 and PL4501 I got voltage for 2 seconds and after 0V. I had to plug/unplug for this 4 coils to get Voltage.
I can't turn off the laptop with the power button. I plug it in, it starts to on. The startup button comes green fix, battery led is orange fix without battery inside and mute sound button comes orange fix after the fan starts spinning 1 sec. Then those...

Lenovo L430 won't turn on
Hello
I plugged a L430 which I didn't use for 4 months. And it doesn't want to power up.
I tried another charger, replace RAM, clear cmos, whitout hard drive and nothing.
When I plug it in the startup button comes green fix, battery led is orange fix without battery inside and mute sound button comes orange fix after the fan starts spinning 1 sec.
When i tried without ram the fan spin but no beep song. I don't know if there are beep song on this laptop.
Do you have an idea please? -

Re: Dell inspiron N7010 won't turn on
I do a "home made reflow" with a gun heater (I had nothing to lose). It works!
But I got 8 beeps at startup. I checked on dell website and it's a Display problem. I changed the Screen, still here. Perhaps the cable is faulty (I don't have spare) or my "home made reflow" doesn't work well
Edit: I forgot to say that I have a display with an external screen....Last edited by Smilo_; 10-29-2015, 02:08 PM.Leave a comment:

Re: Dell inspiron N7010 won't turn on
I need to go further in my research. I think, if I know how to read an laptop schematic should help me a lot. Because I have some problems to link the pages.
A lot of coils on the pcb beeps but maybe only one component is short and this one link a lot component to the ground. I need to probe to the beginning of the schematic, but I don't know exactly where to start. From the power, but I have some problem to follow. I will try to understand how to.
But thanks a lot, I learnt something. Perhaps I should find another...Leave a comment:

Re: Dell inspiron N7010 won't turn on
I put my multimeter on Ohm meter and probeb all coils (I hope). I probeb all coils called PLx (X for a number) that I could see in the schematic.
If was there a short, I should find 0 ohm or 0.001 ohms.
The lowest coils has 32 ohms and the higher has more than 2Mohms. So all coils should be ok?
I attached my shematic...Leave a comment:

Re: Dell inspiron N7010 won't turn on
I don't know if what I did it right.
I took a picture.
I tried all components encircled. I hope there is no more coil on the motherboard, but to be fair I am not sure.
So I tried both side of each. So, with a black circle no beep, and purple circle, all beep....Leave a comment:

Dell inspiron N7010 won't turn on
Hello guys.
I have a problem with my Dell inspiron N7010.
When I want to turn it on, it doesn't work.
When I push the power button, the led power turns on for a second then the led battery blinks once.
I tried to find the "led code" on internet to diagnose, but I didn't find for this model.
I have already tried a CMOS, new charger. I took off the memory and no sound at start up, even without the bios battery no sound
I disassembled the laptop and tried the power plug. It looks fine.
I don't know what to... -

Screen problem Compaq CQ60
Hi everyone,
I have a Compaq CQ60 and since several days it boot but a strange thing happens. I have never seen that before. Maybe this is a GPU problem but to be honnest i'm not sure.
My english isn't very good to explain, clearly, what happens, so I made a short video of my screen.
[URL="http://www.dailymotion.com/video/x2aremo_00010_tech"]http://www.dailymotion.com/video/x2aremo_00010_tech[/URL]
As you can see, after my computer turns on there is different screen color. It looks like a GPU test.
