How To Fix Laptop Power Board

TIP: You should click here to fix Windows errors and optimize system speed.

Working on a laptop computer gives you flexibility and portability. Since it is prone to frequent transfer, manufacturers make sure that their systems can withstand almost every risk including spills, transport and jostling. However, laptops are still prone to wear and tear both inside and outside. Laptop errors may include hard drive failure, system crash, not enough memory and virus infestation.

Apart from the time delays on your computer work and the lost productivity, there is also the issue of expenses to fix the errors, not to mention the calls to tech support. For fatal laptop errors, some cases may require you ship your laptop back to the manufacturer for repairs.

From the Forums

A user in the forum details it further:

After having talked to the manufacturer service dept and finding out that they will charge about twice what I paid for a repair, I took the thing apart and found a smoked capacitor on what appears to be a power supply board. The next boot it came up black. Call the manufacturer again and ask them to sell you just the part as long as you know what it is. Most of them will be glad to send you one or point you to a depot center where u can buy one.  

When I booted it up I heard a "hissing" like noise and the display came up dark but under a bright light I could see the wallpaper and icons. I have a CompUSA notebook with a screen that has gone black. Does anyone know of a source for parts?

What causes Laptop Power Board

While laptop computers may be prone to errors, there are also quick fixes to most of these ailments. If your laptop experience slow hard drive processes like a sluggish file transfer or program load times, your solution is disk defragmentation. Upgrade your RAM if your computer needs more memory and has a slow performance when using several applications. If there is excessive pop-ups, your computer may be infected with a virus.

Run a free virus scan or install an anti-spyware program. When your hard drive failed and create a loud clicking sounds during data access from the hard drive, replace your hard drive or use an online backup site.

Laptop power board issue

It seems as though there are problems with the power circuit board and/or DC jack because the computer does not know when it is plugged in; the battery icon in the taskbar always shows that it is plugged in and because if that I cannot tell when the plug has wiggled loose and so if I am using the laptop for any prolonged time and the plug does wiggle loose (it does not take much for this to happen) and I don't realize it, I don't receive any low battery warnings or anything; the only way I know the plug has come out in this case is when the computer completely dies and shuts off.

I have an Alienware Sentia M3450 and for a while now I have been having problems getting it to charge. Does anyone know why this might be happening?

If it helps, the area of the computer where the DC jack is located often becomes extremely hot-- to the point where I can't even touch it.

Dead Laptop Power Regulator on M/board?

Do I have to get a new laptop or can that part of the board be replaced? When I plug in the power supply to the wall outlet the battery lights up but as soon as I plug it into the laptop the light on the battery goes out. Your help would be greatly appreciated.

The part on the laptop where the battery is plugged in also smells burnt when I plug it back out. Is this a battery problem or is it as I feared, the power section on the board is fried?

Welcome to the forum! Any other signs of running, media drive spinning..? Good luck and let us know. 

Can I replace a Dell Inspiron 15 5000 Series power board with a Dell Inspiron 15 7000 Series power board?

This is a Dell Inspiron 5559.  I also have an Inspiron 5547.  Not sure which exact 7000 model I should get the part for... Are they compatible? Like how Fn+H turns on the hard drive indicator? Is there an easier way?

I want to fix this, as my laptop is no longer returnable and a power indicator is absolutely necessary.  So the only thing I can think of is replacing it with one from the 7000 Series somehow (with some help probably). I don't think Apple has produced a Macbook with a power indicator -- the PC vendors are playing follow Apple.

The systems use different case and mainboard designs -- and may even be made by different companies.  The answer in all likelihood is no.

So Dell made a really terrible decision.  They have a transparent strip in the power button for an LED light to indicate if the power is on.  A power indicator is a given in any laptop, no matter how cheap it is.  However, Dell in all of it's genius decided to not include an LED bulb on laptops up to the Inspiron 7000 Series, despite leaving a transparent slot for it.  Seriously, what happened to this brand?!?  Do children make these laptops now?

my hp tx1003au not on with power without power with battery even another adopter some says short circuit in mother board which

Power light won't come on, power to board

I don't have a multimeter to test the system with and I don't know if it's more than a passing problem. I remove the cable and molex plugs from both HDD's after the power is off and set it back to the way it was. Okay first I extra a harddrive from an HP older system that had just recently crashed. Weird, never saw that before, I think crap maybe the IDE cable is set wrong or something.

Very strange. Now I want to read that drive right? I put it in as a 2nd drive in my Dell Optiplex system, set the jumper to cable selected, go into BIOS and select my 1st drive to show it as AUTO.

I undo the front panel and work to see if the cable is worn but it is not and it appears to be fine. The light to the signal will not work to go green at all. Now the system won't even power on. I have never encountered anything like this were a system worked fine then you attempted to just read a 2nd HDD and it started to cascade a bunch of problems to the system.

Well I go back again to check my work and see it is fine with how the IDE cable is sitting and the Molex plug.

Older Dell Optiplex GX260 tower model. I hit Save changes, upon rebooting it, it gets to the end of logo display and freezes. What do you think could be most common issue of this and why?

The light to the MOBO is on but the system won't start. When I reboot I get to the end of the logo again and it freezes and I can't even get into BIOS.

More power to the board to help?

I am currently using an Asus Sli-deluxe motherboard with an x1800xt videocard. I already have a 6-pin connected to the videocard but theres also a spot on the motherboard for a standard 4-pin connector from the psu. (4-pin just like the hard drive power connectors) Will connecting my psu to this 4-pin plug be helpful to maximize and stablize the performance of my card or am i fine with the direct 6-pin already?

plug the 4-pin plug in, it is suppose to be there and will help every thing and yes the 6-pin needs to be plugged in.

Board has power but nothing else, what's going on?

I know that it is good because as I said it was working only moments before the transition. I am using a NVIDEA FX 5200 128mg video card that was working on my previous board moments before install on this board. The power button for the case is not working at all...on or off.

Is the CPU installed correctly and is it's fan plugged into the motherboard?

I know this has got to be something simple that I am just missing but I am completely baffled. Please help!!

Have you remembered to plug in the auxillary 4 pin 12 volt power connector to the socket near the CPU if it has one? The most baffling part is that I am not using the power button..It is doing this when the switch on the back of the power supply is flipped.

I am also putting it in my case that I have been using with a ANTEC SP350 power supply. (the previous setup was a 2.4ghz setup so I am sure it is enough power)
The problem is that when I turn it on everything seems to get power...the fans start and the hard drive light stays on but no video, no post and NO BEEPS.

I just bought a Soltek SL-k8av2-rl Rev:LB for my brand new AMD Athlon 64 +3000 Socket 754.

Different power board on monitor

help please with usb/power board question

However if this daughter board is a combination USB and Laptop Power connection type daughter board, the USB portion can be disconnected  where you have your arrow pointing to the connector of 4 or 5 wires and leave the 2 wire red/black portion of the cable connected so that you can still charge your battery and run it off of the wall outlet etc. Without a view of the ports on this daughter board I figured I'd mention that. The other one with 4 wires is the USB cable which is both USB Power and Communications. *From the looks of it, they are powering this daughter board for the USB through the Red/Black  2 wire plug that has no problem from what you stated. The laptop will run without this cable, but the USB port will not function.

Some are USB only and others have multiple purposes such as Ethernet, Audio, DC Power to Battery Charging Circuitry, etc and are designed this way with featrures on daughter board so that if cable(s) are yanked from laptop, its not damaging the main motherboard, but instead an inexpensive daughter board which makes for a cheaper and easier repair.I bought a USB daughter board with cable for a Toshiba on ebay to replace a busted USB port for a customer and it cost me just $20 for a good used one with free shipping. But if you have no need for this USB port and do not wish to replace the damaged cable, I would remove the cable to avoid damage to the laptop.

Power supply without the board

I have a power supply and want to see if it works without having to disconnect my power supply presently in my computer.

I know this is a windows forum but there are so many people who are hardware guru's as well as windows' so sorry for those whom are offended... AT supplies don't.

I remember when I bought it from the display at the store where it had a little jumper wire somewhere on the terminals to simulate the board being plugged in.

Any one know which 2 terminals get jumpered to make this work? oh yeah it's an xt power supply. Or perhaps where I can get the information?



An XT power supply has an on/off Switch attached to it.

Power Box Or Mother Board?

you might have cracked the motherboard and cant see it Only lights come one.  Could the mother board of cracked and i just cant see the crack? Could i have gotten  bad power supply? Could something of fallen off the motherboard that would make it not run? So i took a good look at the mother board, it isn't cracked and nothing looks fried. It was a goner.

When i found out i opened it up to see if any other pieces had fallen off, nothing looked unusual on the mother board.  I have an E Machine W3507 it has a Celeron D Processor 2 gigs ram ( upgraded ) ATI Radeon Xpress 200 video. I replaced the power supply and now the power light and a light on the mother board are the only things that come on. Nothing turns, the fans don't work.

A friend suggested a piece feel off that i didn't notice. I took out the power supply to see what the damage was. Every thing but the ram is factory. My husband had it in a questionable position, and it fell and the power box plug-in shattered.

Board doesn't power on

If I remove the power cable, it can boot up and works fine. The power supply is ok (it outputs 19V, as it should). First I want to thank you for the great job you do in this forum!​ ​ I have a PackardBell Vesuvio laptop. If a laptop boots with/without a battery, or with/without AC connected, it typically implies a motherboard malfunction.

All other components seem to work fine. Hopefully someone with more experience can confirm.

I'd be grateful if you have any ideas about this problem!​

I don't work much with laptops, but power related issues are generally a motherboard function. I had problems with the previous motherboard (it couldn't power on) so I bought a used board in eBay.​
But this one has a strange problem; it can't power up if the power cable is plugged in (with battery inserted)!

After powering on successfully, I can insert the power cable and battery begin to charge without any problem. I don't know if the used motherboard I bought was faulty or something else is happening. Is it possible that something inside the laptop is being shorted out when I plug the power, preventing the laptop to boot up?

new board wont power up

when i turn it on the cpu cooling startd to spin then stops. is it the power supply or motherboard??

i just purchased a new P4-2 with a new fucture motherboard FP-i845P4 and a new powersupply. Nothing else from there.

if i let it set for 1 minute it will whirl the fan again, then nothing.

Alienware X51 R1 power board

I've tried to chat to Dell support North america, so thay told me it's not a problem to buy it in US and Canada, but they cannot sell and send it to me... So I've already know that I just need to swap poverboard from R1 to R2. I've decided to upgrade my Alienware X51 R1 (i7, 16Gb RAM, GTX 660) to a latest videocard that my system can use: GTX 970. The art of it in Dell spare parts is D85RT.

So where, how can I buy it in Russia and what's the price of it. But I know about some problems with this: the original powerboard that came with R1 version is not proper working with theese videocards.

cpu would not switch on, but board gets power.

Provide links to the components. post the EXACT make and model.

please help me guys....

You need to post your system component specs. Motherboard; EXACT make, model and revision (if applicable).

Power Supply; EXACT make and model. No one can possibly diagnose a problem without knowing the EXACT components you used in the build. Graphics Card (if installed); EXACT make and model. Memory; EXACT make and model.

If the machine is a mass produced machine such as Dell, Gateway, HP, etc. can anyone tell where the problem , in PSU or motherboard or the HSF or any other place so i change it . my cpu is not switching on , but the motherboard get power , which i can say since , the keyboard ,mouse light glows and i can charge thorough my usb ports , but the cpu fan starts to run and stops abruptly .

Processor; EXACT make, model and stepping.
