You have posted to a forum that requires a moderator to approve posts before they are publicly available. The price for a new battery and ac adapter is ludicrous anyway but I'm certainly not going to be buying new ones when the help topics needed to test them say they are both working fine. I also updated my BIOS but both times I opened the downloads it blue screened my laptop and shut it down. I have a dell studio 1555 and replaced the battery, months ago i would sometimes get messages that my ac adapter could not be recognized, but i would just unplug it and plug it back in and it would be fine, but a few months ago my battery wore out, so i just no replaced it but it will not charge now. Quick question I bought an universal battery for my Inspiron 1545, battery works fine but now that I plugged in the adapter the laptop does not recognize it..do I need a new adapter or is it the battery? Dell battery is not recognized by the laptop and is not, Original title: battery wont charge my dell laptop will not reconize the battery in it therefor will not charge it also.
Plugged in but not charging the laptop battery - battery, I purchased and installed a replacement battery for our 2012 hp laptop, but it wasn't charging. If the adapter tests fine and output correct voltage, disassemble the computer and remove the top cover. As you see on the first picture, in my example the power adapter plugs into the DC-IN power jack which is connected to the motherboard via a harness.
Plug in the power adapter and measure voltage at the point where the DC-IN jack or DC harness (like in my case) connected to the motherboard.
If you are reading the same voltage as on the AC adapter, it means the power jack or harness works properly and the problem is related to the motherboard. If there is no voltage, most likely there is a problem with the jack or hardness and it has to be replaced.
I have a gateway mx6214 laptop, i was plugged in using it one night and all of a sudden the charging to the unit stopped, it kept working but would no longer recognize the charger.Would a bad motherboard function properly like this or should i have the jack checked?
Somehow, the DC-in jack is loose and will only register the adapter if it’s pushed in a certain way. Hi,on my laptop hp dv9005us, i have a light in power jack but don`t have any light on front panel,no light like charging, when i try to turn it on i have no response. I have a Toshiba laptop that is also given me stress The Led comes on and the computer does not come up and sometimes if you try to put it on it will come on but it will not booth, what could be wrong with it. The power light and the wireless light stay on when the power button is pushed and the fan comes on. I’ve read though some websites and found that it might due to the condenser on the motherboard. I have a HP pavilion ze4600 (ze4610us) WhenI plug it in the battery charge light is flashing.
If the laptop is absolutely dead even when you use a know good power adapter, most likely you have a problem with the motherboard. Any input is helpful, as long as it does not involve using multimeters and tinkering with the motherboard. Having same problems with the toshiba screen, m305d-s4380, the screen flickers, i have found that applying a bit of pressure on the borders of the screen the flicker is gone, so i have done a research, everything seems to be a problem of the lcd cable, Question.
Now when i try to turn it on, the lights all come on and the fan starts up….but no screen or anything??
Iam Gordon from Uganda, East africa, i do have a tropix laptop, it doesnt show anything on screen when i start up. Now when i try to turn it on, the lights all come on and the fan starts up….but no screen or anything?? Any second opinions would be greatly appreciated before I go and spend a smaLl fortune on another notebook…..
I have a acer aspire 5630 for while, but now its not working properly, when I tried to start it, the fan runs only for 5 to 10 seconds and after that there is only power led on but nothing else is going on, i can’t hear hard disk sound etc, any suggestion???

Before replacing the motherboard, I would suggest testing the laptop with another AC adapter.
It’s not necessary to buy a new motherboard directly from Dell but buy it from a reputable seller. This is actually the 2nd motherboard I have come across with the same fault & still cannot solve this problem. But I can’t locate the fuse on the motherboard, anyone has a pictures or a website that I could use? But I can’t locate the fuse on the motherboard, anyone has a pictures or a website that I could use? I can’t find the fuse on my HPDV 9000 do you have any website or manual guide I could use to locate it? In order to start any laptop with video you need three main components: motherboard (with video card), CPU and memory. From my experience, CPU failures are not common, so most likely it’s either motherboard or memory failure. If the problem is still there even with a new AC adapter, probably it’s bad motherboard. I have an HP Pavilion dv6500 laptop, it does work with charged battery but not without battery and with charger on. Could it be the power connector board (DC input jack and circuitry that transfers the power to the motherboard) or the motherboard itself? The voltage outpot on the replacement adapter has to be exactly the same as the original adapter.  The amperage on the new adapter could be the same or highter.


Took apart a dead Dell battery just to show you how it looks like inside.  Connected this battery to the laptop and the laptop did not detect it. Use a current limiting power supply to power the +5V rail, and using a millivoltmeter, attach the + lead to the +5V rail and use the – lead to probe all the +5 V nodes of the board looking for the voltage increase as you get close to the short. The Dell™ Latitude™ D430 laptop is an ideal lightweight solution for business users who travel frequently.
The maximum current drawn from the AC adapter is programmable to avoid overloading the AC adapter when supplying the load and the battery charger simultaneously. Press the F2 key to enter computer’s BIOS Setup during Power-On Self-Test, or POST, process  while the Acer logo is being displayed. Press the F10 key and then press the Enter key to save the changes and restart the computer. Original Title: battery wont charge my dell laptop will not reconize the battery in it therefor will not charge it also. I have recently replaced the battery on my Acer Aspire 5742z laptop because the OEM one was going bad (30-40min life at 100%).
You plug in the power adapter and press on the power button, but the computer will not react.
It’s very likely that there is noting wrong with the laptop and your problem is related to the power adapter. Do you see any LED light flashing when you press on the power button or plug in the AC adapter? I assume you tried replacing RAM with a known good module, so it’s not the RAM problem. Somehow, the DC-in jack is loose and will only register the adapter if it’s pushed in a certain way. So, I unplug everything for 5-10min to discharge that condenser than carefully starts again. I push the power button and then both the blue power light and the yellow charging light are flashing on and off.
Usually it’s integrated into the motherboard and your description sounds like a problem with the motherboard.
When i plug in my adapter, the laptop doesnt respond(does not charge battery, doesnt turn on, leds do not respond…etc). I think in the comment 24 you asked about the power button board but called it power board.
When i plug in my adapter, the laptop doesnt respond(does not charge battery, doesnt turn on, leds do not respond…etc). When turned on, the screen shows “Sony” logo and then a short blinking “-” at top of the screen and then nothing, screen dark. When I connect the power lead the battery charging light starts to flash, If I press the on button the charge light stops flashing with nothing else happening. I turned it off 1 night and started it up like normal and it froze as soon as i opened a program, now when i turn it on there is no Bios screen and it just keeps restarting itself. The power, and battery lights show, DVD rom runs but shows nothing, i have tried to observe it and it runs then stops, removes the power light then starts again but without displaying anything.. It wont power on with battery or mains supply, At first it would power on after waiting 5 mins , this then extended to hours then days and now its weeks before i can power it up again.
When I plug the ac adapter into the wall ac power outlet; the light on the ac adapter is solid green at that time. If you still experiencing the same problem with another adapter, most likely this is the motherboard failure. Usually in Dell laptops you can find the motherboard number on a sticker glued to the memory slot. The problem I have is the compter wil not charge the battery or work when plugged in (if the battery is removed). After that I tried to boot it but no reaction just the blue light where you plug the adapter.
Whenever I hit the power button, the thing turns itself on and off several times before it finally reaches the POST and boots. If you still experiencing the same problem even with known good memory, this could be motherboard failure. If you have two memory modules installed, try removing them one by one and test the laptop with each memory module individually. It’s possible the laptop will not turn on because the AC adapter is dead and the battery has no charge.
Soon as the current drawn about an amp or two, place your finger to any electronic components in the main board. Try removing DVD drive, hard drive, other devices you can access and start the laptop without them. Maybe there is a short inside the cable and when you move the plug, you actually shorting wires inside the cable. It would overheat aLOT and then finally one day while I was sitting with it on a board on my lap while playing a game, it just went out.
Ive tested my adapter with a multimeter and it shows the normal voltage,ie, the adapter is good.
I opened it and noticed that fan comes on for and then stops, and the housing containing the fan heats up tremendously with fan not working.
If one of the memory modules is bad, the laptop should start with video when only a good module is installed.


It’s very unlikely that both memory modules failed at the same time, and if your problem is memory related, the laptop will start properly when the bad module is removed. As soon as I connect the ac adapter’s plug into the laptop the light on the ac adapter blink and make a clicky noise until I unplug the ac adapter from the laptop.
Ill try another AC Adapter but I dont think its the problem since I can’t start it with the battery. Ill try another AC Adapter but I dont think its the problem since I can’t start it with the battery.
Occassionally, when power light on, the fan rolls for 5sec, with no sound and nothing on display. There is a long string of number on the sticker separated by dashes and one part of number will look like CN-0MD666.
In order to replace the fuse, you’ll have to desolder the failed one and solder a new one.
The center pin on the AC adapter connector is an identification wire connected to an IC chip. After that you test the fuse with a multimeter and if it’s open, replacing the fuse might help. If you still experience the same problem, apparently you have a bad motherboard or video card. One thing I want to make a point here is about testing the output of the power supply or adapter.
I let it cool down for a good couple of hours or more and went to turn it back on and nothing.
I inserted the Recovery DVD to re-install Vista, and I could hear the DVD being ‘read’ by the laptop, but nothing happens. The adaptor light blinks when I connect it to the power supply, but as soon as I plug the jack into the laptop socket, the light on the adaptor goes off. I have removed various caps, coils, resistors etc but still cannot work out where the sound is coming from! The only thing that changes anything is when I push the function buttons media keys over and over and pretty quickly it changes the flashing blue power lights flashes it will start flashing with how I am pushing these keys.
Same thing as you, the lights would come on and the fan would run briefly and then off again and nothing else. Runs normal when powered on, and if I do a soft restart, it shuts down and powers up normally. I have tried listening all over the board by ear but the ticking sound seems to be the same – neither louder or softer. Means they must be connected to the laptop and the laptop must be ON then you can actually use your multi-meter to measure the voltages.
But if I shut down completely, the next time I hit the power button I have to hit it over and over until one time it works.
I have tried removing the battery and running only on AC power, but it shows the same symptons. Are there components on a motherboard that would be more prone to tick when they have failed? If battery is charged i get 7 led signals when trying to switch on and power led blink and go of again. However, do you realized that all the desktop computers used switching power supply with cooling fans attached to it? He says it would basically cost me as much to buy a new laptop as to replace the mb in this one. I have tried removing every component and powering the motherboard directly, but with the same results. I am assuming that the motherboard is faulty; where can I directly purchase a new one; can i purchase a particular model of motherboard directly, or will i have to deal directly with Dell? Now I sit and wonder if this really could be the problem or if it is the power supply as mentioned in a few other articles above. If a particular component soldered on the motherboard (like power jack) is faulty, is it possible to remove it, purchase a new one and solder it back?
Now think about this, why in the world that the power adapters for laptop has a sealed enclosure and no ventilation system? The more you use your laptop, the more you ruin (not knowingly) your adapter because of overheating. That’s why after one year, you will experience some problem with the laptop just because of the lack of ventilation of the power supply. The switching power supply inside the adapter is composed of a transformer, diodes, capacitors, resistors, transistor and voltage regulator. The last two components are the one resposible for discharging HEAT into the two metal heatsinks. If there is no ventillation inside the plastic enclosure, this two semi-conductors will suffer and the mother board will be affected. These holes will help to dissipate the heat inside the enclosure and will reduce definitely any electronic problems of the laptop.
