id="msg_1476977_quick_mod"></div>								</div>							</div>							<div class="post">								<div class="inner" id="msg_1476977">Hi everyone,<br/><br/>I know that this is likely a futile endeavor, but I have a defective (yet optically pristine) laptop mainboard here which I would very much like to repair if possible. The CPU and GPU are still pretty powerful (i7 4720HQ, GTX 960M) and a replacement would be uneconomical, so it&#039;s at least worth a shot.<br/><br/>Due to the nature of the failure, there may be a glimmer of hope: It conked out under full load while running a game, drawing nearly peak power (around 100W). Now it is completely dead, not even the battery indicator light will turn on when I connect the AC adapter. I am therefore hoping that the issue is related to power delivery. The first thing I tried was unplugging the battery. Then I tried swapping the AC adapter and using this device&#039;s adapter with another device. The AC adapter works fine, but I noticed 2 things when plugging in the other (different model) AC adapter: It started chirping in ~1s intervals. Also, The original adapter (which is not chirping) will provide 19V when freshly plugged into the wall and its voltage permanently drops to a random low value (such as 3V or near zero) when I plug it into the defective board. It does not have a &quot;smart&quot; pin btw, so I am a bit curious why there are 6 wires coming from the jack.<br/><br/>I am not an electrical engineer, but experience leads me to suspect something shorted out? I therefore measured for continuity at the power jack, but my multimeter says it&#039;s an open circuit. However, since 2 wires become 6 at the board, there might just be some &quot;smart&quot; wizardry going on and the short circuit may only occur once 19V are delivered? The 3 cell battery also seems to be very &quot;smart&quot; with 10 wires coming from it and only like 0.01V coming from the 3x2 cell wires while it is unplugged.<br/><br/>The machine saw some heavy use over the last ~3 years, but the CPU was slightly undervolted, the GPU was mostly underclocked, high performance thermal grease was applied, the fans were regularly cleaned and operational and the laptop was even propped up a bit in order to reduce heat/strain, so I don&#039;t believe the CPU or GPU died.<br/><br/>I finally poked a few components such as the VRMs with my multimeter leads and didn&#039;t get any readings I would consider suspicious, but I don&#039;t really know enough about electronics to analyze the readings. I DO know that you can&#039;t really measure much while a component is still mounted though...<br/><br/>Does anyone have a suggestion what I could try next? It would be much appreciated. Besides the multimeter, I have a soldering iron with fine tips and enough experience to remove the bigger components. I do not have any tools for SMD stuff, but I know someone who could help me out with that if there&#039;s something worth trying. The images below are as high-res as the board rules will allow, if you need better quality let me know and I will upload them somewhere else.<br/><br/>Thanks in advance!</div>							</div>							<div id="msg_1476977_footer" class="attachments smalltext">								<div style="overflow: auto;">										<a href="https://www.eevblog.com/forum/repair/help-identifying-the-faulty-component-on-a-laptop-motherboard/?action=dlattach;attach=411480;image;PHPSESSID=6aqov3i1nujn3efk0k4d93esk2" id="link_411480" onclick="return expandThumb(411480);"><img src="https://www.eevblog.com/forum/index.php?PHPSESSID=6aqov3i1nujn3efk0k4d93esk2&amp;action=dlattach;topic=107818.0;attach=411481;image" alt="" id="thumb_411480" data-pagespeed-url-hash="1523862441" onload="pagespeed.CriticalImages.checkImageForCriticality(this);"/></a><br/>										<a href="https://www.eevblog.com/forum/repair/help-identifying-the-faulty-component-on-a-laptop-motherboard/?action=dlattach;attach=411480;PHPSESSID=6aqov3i1nujn3efk0k4d93esk2"><img src="data:image/gif;base64,R0lGODlhBwAQAIABAAAAAP///yH5BAEAAAEALAAAAAAHABAAAAIWTIB2CuvZYlyQTknP1bniu3mcATZGAQA7" align="middle" alt="*" data-pagespeed-url-hash="1056080391" onload="pagespeed.CriticalImages.checkImageForCriticality(this);"/>&nbsp;Bottom.jpg</a> 										(982.81 kB, 3300x1792 -

Good idea, I checked that rightaway, thanks! I Unplugged it from the board, inspected it closely and wiggled it around a bit while measuring, hete&#039;s what I learned: The 2 wires from the AC adapter are just split into 3 wires each and while there is of course continuity between these 3, there is none to the other 3 wires even when wiggled. Measuring the pins on the board, they are also 3 pins connected each and at first I measured a 650 ohm resistance between the pairs of 3. After plugging in the AC adapter, resistance actually went up and there is now no connection between the 3 pairs? Don&#039;t know what to make of that.<br/><br/>The board is from an Acer Aspire VN7-591G. I left that out because it&#039;s a bit embarrassing. <img

That means that something is drawing a high current. After a bit further inspection I noticed something odd looking: On the Top side, on the left half there are 3 similar devices PU8202, PU8203 and PU8205. Can you check if they are looking OK? Especially the 202 and 203 seem to have something on the right side of the device that looks odd. It could be an artefact from the cam. That area seems to have a slight changed colored PCB too. That is an indication of heat. So a closer visual inspection of that area might useful to identify the problem.<br/><br/>But other than the power jack and the visual inspection I haven&#039;t anything I can add here. Sorry.

mentioned. yes, there is some discoloration due to ~2.5 years of being subjected to quite a bit of heat. it&#039;s the uncooled side of the hottest area on the board and acer ran the cpu and gpu <em>pretty hot</em> (95°C, equivalent lenovo machines throttle to only 85), even though the laptop had dual fans and heatsinks where most others only had one. this was nice regarding the noise level, but i was always a bit worried about the temps, hence all my countermeasures. <br/><br/>regarding the artifacts, sadly that was just some residue from a protective sticker. i was able to wipe it off with some naphtha and took some new pictures afterwards. i also poked the 3 devices with my multimeter and (considering that 05 is upside down) they read pretty much the same so sadly, it doesn&#039;t look like one of them burned out.</div>							</div>							<div id="msg_1477192_footer" class="attachments smalltext">								<div style="overflow: auto;">										<a

share them via pm?<br/><br/>Regarding the equipment front, I haven&#039;t been so successful (yet), but I can jury rig a decent magnifier with my phone / have pretty good eyes and the probes I have allow me to reach <em>most</em> of the spots on the board. Stuff like the feet on the &quot;nuvoton&quot; labeled chip or similar components would be tough, but if there is a problem with any of these, I&#039;d have to hand it over to a pro anyway.<br/><br/>So I opened the boardview with BoardViewer and familiarized myself a bit with the software.

Using my two cheap multimeters, I am getting around 0.3 Ohms. Interestingly, the value drops a bit during the first few seconds of measurement, but I am assuming that&#039;s because my multimeters are so crappy (they are also doing this when I am just shorting my probes and I already subtracted the value that remains in that case). Will also measure with a proper ohmmeter at work tomorrow (it&#039;s the first chance I get).<br/><br/>Yes, I do have access to a CC bench power supply at work!&nbsp; <img

rail that provides power across much of the board is called DCBATOUT on my model (see attached screenshot) and there is definitely a short to GND. Using my two cheap multimeters, I am getting around 0.3 Ohms. Interestingly, the value drops a bit during the first few seconds of measurement, but I am assuming that&#039;s because my multimeters are so crappy (they are also doing this when I am just shorting my probes and I already subtracted the value that remains in that case). Will also measure with a proper ohmmeter at work tomorrow (it&#039;s the first chance I get).<br/><br/>Yes, I do have access to a CC bench power supply at work!&nbsp; <img src="data:image/gif;base64,R0lGODlhFwATAMQAAOXl5ebTBa+vr2FaDdfX1xcVBMnJyf7uNv/vR//rF9XEBf/tJvDw8MW1A7anA/7+/v/rC//qBPrlBZSIA6mbA4d+IfPfBEU/AtXJQuPWQ5qQKvf39wAAAP///wAAAAAAACH+HUJ1aWx0IHdpdGggR0lGIE1vdmllIEdlYXIgNC4wACH5BAkAAB0ALAAAAAAXABMAAAXNYNdxJCeeaIqSG0Oq8Pq0hBnH3AzUaTH8g4Iqt9nZRhWEEnE4VI6jB8MoKmCWzcNioRCKSFNeIaNsbreJRMA7CpM0Zc4izUlAIJHJt/TKLup3HHgSFmssDAQGJGYJghERHBGEAQEXRDsGAnJzdo+PkwEKA5eJJJx4npKFCg2jfCVpd6mTrA0XbZiaEpASvYSrHA4OQhxTBpkcExYWHJSUCgrBDgN7rwUKlK/BFBNeJImZmgUO0A3mwtxsI9ojAw3CDhQUozcqBRf4F+odIQA7" alt="&#58;-+" title="ThumbsUp" class="smiley" data-pagespeed-url-hash="2919269608" onload="pagespeed.CriticalImages.checkImageForCriticality(this);"/><br/></blockquote><div class="quotefooter"><div class="botslice_quote"></div></div>That appears to be a real short on the DCBATOUT, usually a faulty MultiLayer Ceramic Capacitor. <br/>A shorted buck regulator high side MOSFET can cause what appears to be a short because the DCBATOUT rail becomes connected directly to the supply rail for one of the large ICs, the CPU for example, which have a low resistance on their supply pins. This can be as low as 5 ohms.<br/>&nbsp;There are various methods for finding suspect shorted MLCCs. I apply 0.5V limited to 0.5A to the rail and track down the shorted part by measuring&nbsp; voltage drops across the ground plane. This might be too complicated for a one off. <br/>&nbsp;I haven&#039;t used other methods, so I should leave it to others to explain first.</div>							</div>						</div>						<div class="moderatorbar">							<div class="smalltext modified" id="modified_1481348">							</div>							<div class="smalltext reportlinks">								<img src="data:image/gif;base64,R0lGODlhEAAQAKIEADMzMwAAAP8zADMKAP///wAAAAAAAAAAACH5BAEAAAQALAAAAAAQABAAQAMxSLrcDlAMFZyCQNq96gIExl0hlgWoR4qNOlJpCb5yWD/Qp+FzuLsiEAuYs7heR5oiAQA7" alt="" data-pagespeed-url-hash="2579805057" onload="pagespeed.CriticalImages.checkImageForCriticality(this);"/>								Logged							</div>							<div class="signature" id="msg_1481348_signature">Hioki AS100D vom, HP 54645A dso, Fluke 87V dmm, AN8008 dmm, Agilent U8002A psu, New!

to power it up and test, as it will just be a power rail filtering cap of some sort. The laptop might crash if it tries to boot, but it should at least power up. But for the longer term you should replace the cap, as it will be a decoupling cap of some sort, and being doubled up like that, it probably needs both to reduce current stress on the cap. A few minutes run won&#039;t hurt the one left, but hours of use may be a different story. <br/><br/>Anyway, nice find! I hope you find the value, and get a replacement. <br/><br/>PS what are the &quot;little brackets&quot; holding it in place you mentioned? Can you take a pic? These components usually just sit on solder pads on the board, and there should only be solder holding the cap onto the board - the metal ends are part of the component. Its the only part of what you said that is worrying me. <img
