    Hello

Now was doing exactly the same music videos and puff again same issue... the ddr3 stick works fine in another mac so there is something wrong with motherboard... tried to adjust screws checked 0.75v present and all is fine... no other mem stick works im any slot of this macbook.... is there a common issue here that you can help me with??? thks in advance guys....

          thanks Mon2 it is very likely that the CPU is bad, since i remember some months ago i did a reflow to it , to make it work again under a similar issue..... the ddr3 sticks are fine, and the contact in slots also fine,,, so they might be the inner tracks inside the board to reach the cpu or the cpu itself semi toasted.... thanks but this willl be trash

              Trying to troubleshoot DDR4 SODIMM slot with slot tester
              by Lifeisfun
              Hi folks!
              I have some kind of memory problem on Lenovo laptop. I was initially able to install windows after several tries since the laptop did freeze in middle of those attempts.
              Eventually I discovered that it was related to moving the laptop.
              Later on it even stopped booting unless I pressed around the memory slot. (no keyboard LEDs only power button responds)
              If I remove the RAM I get the beeps that RAM is missing. Inserting the RAM there is silence and it will not boot most of the time. No picture.

              I removed the board got one of those memory slot testers...

              Need help to replace burned resistor in 350w atx psu
              by mikey5791
              Hi to all forum members,

              Got this faulty 350 watt atx psu dirt cheap from a local online seller as i am keen to use it as a learning tool to repair faulty power supply.
              The faulty part is quite obvious from the burn area near the 16pin KA7500 BD pwm. The fuse is still intact with good continuity.

              Upon power on ac, there is 5vdc standby power on cathode of diode D14 and about 10vdc on cathode of diode D13.(This should be the aux power to generate the 12v and 5v rail.)
              Initially i replace the two burned resistors near my marked red arrow to 200 ohm resistor...

              A1286 820-2915b chime ok, but no image no bklight
              by marce002
              Hello

              I have this a1286 with minor water damage, after cleaned ISL area turns on and chimes , load os but: no image no backlight.... LCD_PWR_EN is 0vol ..
              I have done gmux bypass to many a1286s with gpu issues, so though this would be the case. routed jumpers to avoid the gpu and removed resistor r8911 as usual to disable ati gpu... but still no LCD_PWR_EN signal...

              what can be going on to not have LCD_PWR_EN enabled? i do have 3.3v in pin 4 at lcd connector but not pins 2,3, because u9000 is not enabled by this missing LCD_PWR_EN

              thanks in...

              Lenovo Ideapad 3 15IIL05 working perfectly with onboard RAM but it doesn't start when I add a memory into the RAM slot
              by szepesif
              Hey guys!

              I don't know the solution to this problem, but this is definitely not unique and I would like to figure out the solution to fix these in the future.

              I have two identical Lenovo Ideapad 3 15IIL05 laptops with integrated 4GB DDR4 memory. Both work perfectly with that. BUT... if I add any extra memory to the single RAM slot, it never gives a picture. I thought the RAM slot pins would be the problem but no, all pins are solid (I checked them under the microscope). The RAM in the slot has 1.2V, so the voltage is present on the module. I flashed the latest BIOS, so
