I've a doubt about one component but could be the hard disk controller, it hasn't 28 pins and any label on top, i've signed in red on pitcure. Yes they are pulses that you can hear with an audio signal-tracer. This component has 28 pins, on motherboard there's not nothing to similar. Thank you very much for attention and excuse me for my bad English. Now i must know and try which of these are equivalents. With battery plugged the charge circuit works and charge led is on, the laptop starts but the screen doesn't turn on and the cpu fan doesn't work. That battery may be a rechargeable type, not needing replacement.

At the moment my suspicions lie on the charging control circuits and the mosfets nearby, still, it would be great to have a proper schematic or layout to know what I'm doing The laptop suddenly and abruptly shut down while watching a video file. I've read they are in the order of khz. I've a doubt about the schematics because i don't found the same name and type of device on motherboard. I've checked voltage up to the charge controller and the 19v its ok. I think there is some bad component on line that supplies power directly the motherboard because when i put the battery status led is on, when i put off and insert only the cable all leds are off and the all circuits look dead. Medion Akoya P6648, it doesn't turn on at all.

I've found another laptop similar to my model and i've charged the battery. I know it's very difficult, but you can post your results, and ask for help. When i've pulled in and out the ac power cable few times the laptop stops. Check the owner's manual on reset of those modes. When i'm remounted the battery on own laptop i've seen that it works fine but not charge. Most laptops have three, one being the main power battery.

Due a jack repair the polarity has been inverted so the lapotop, when there's no battery plugged, doesn't turn on, dead, no led blinks, no fan. I have another one of these with a similar problem. Moreover, i've test all components in the section, there is only one zener that i'm not sure. If laptop runs with charger, it's obvious that it has 19 volts in all circuits, then probably the problem is in the chip that controls the charger circuit. You can get ideas from Internet. I've find this service manual It's right? From there, try to locate the chip than control the charge circuit , and look for its data-sheet over the Internet, then study it and try to find out all the information you can.

In the photos seems to be that it is right. I've found 1v without battery and 3,25v with battery half charged. If left in 'sleep' or 'hibernation' mode too long, it could have shut down or lost its restart cache. In the evening i would reopen the laptop to follow Francisco's suggestions. The logo on them should be a white or silver color. Meanwhile it protects adapter when system or battery is shorted.

Could be an another model of smbus controller? I have since my last post tested the motherboard while plugged in, and there are no 3. When i insert the battery all the leds are on and the icon on windows bar shows the charge state on. If i try to follow the circuit the components don't match the schematic. Whit diode test i've continuity in bias and in reverse bias value readed more higher. Have noted some replacement E89382 motherboards listed from a search. When i've remounted the laptop, it started and worked for 2-3 hours without recharge the battery even if on windows status bar the plug-in icon was in ac mode.

. I'm not sure i can ear something with this frequencies. Also, how was the laptop shut down from its last use? The frequencies you mention, refers to the Buck Converter, not to the communication bus. There are at least two schematics. Today i am going to show you How to Download Schematics Using Motherboard Part Number or motherboard model number Laptop Schematic Diagram is easy for repairing work.

So i can say it's an issue on charger circuit. Hi, I don't think problem is due to reverse polarity, in page 38 we can see that this circuit is protected for this kind of issues. If the heat sink and cooling system was not up to par, then a possible cause. Quote: Due a jack repair the polarity has been inverted I think, I misunderstood you. The laptop suddently and abruptly shut down while watching a video file. I've attached pictures from front side and back side, too. .
