How To Fix Laptop will not power on

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:

afew days ago i was using my laptop as normal running on AC power, but after it being on for about 30 mins the backlight started to dim and brighten quickly and the icon in the system tray was also quickly changing from the Ac icon to the battery icon, after about 10 seconds of this it automatically switched off. (backlight was changing because its set to dim during battery usage) i left it alone for a good hour or so, when i tried to turn it back on it would not power on. when the power button is pressed the power light sometimes flashes on for about a second before turning off again. and also some laptops do not even power up even if the cord is plugged in if the battery is not in good condition.   No charge = no power.

Make sure that your charge indicator is blinking when you have the cord plugged in. It may not be charging the battery properly. any help would be great, or even ideas what it could possibly be, if you need any more information please ask.   your cheapest place to start is with the charger, then the battery.

Having said that, if the battery is not functioning as it should, it will not charge. also when the battery is connected and the power cable plugged in the battery charge light is lit. it is a HP laptop, and nothing new has been installed/changed recently, its 2 maybe 3 years old.

What causes Laptop will not power on

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.

Can't power on the laptop and battery power icon is not shown though laptop is plug in

How can overcome the problem?

My laptop ( Dell Inspiron Nseries N4110)   cannot be power on though adapter is plug in and even power is not displayed in battery icon.

Laptop not receiving power. I see power was coming to AC adapter but laptop was not receiving power.

I tried connecting the charger to the laptop and removed the battery to check whether power is getting supplied then i came to know that power was not getting supplied to laptop. Charger is working fine but battery was not getting charged. Do I need to change the charger socket in the laptop? 
Please help me to fix the issue.

I am using Inspiron 15R 5110 Laptop.

My few days my laptop was not receiving power.

Laptop Power adapter doesn't work when laptop is on. But it charges the battery when laptop is off

Could be a bad power adapter. Obviously, the battery doesn't run forever. its almost a year and half old. When the laptop is off, the adapter works fine and it charges the battery.

It may charge, but it doesn't have enough power to keep the system running, so it switches to your battery. I have a HP laptop (G62). I'd look at getting a new power adapter.

Everything was fine but I am having problem with power adapter for few hours. Anybody had this issue before or any suggestion? But when I turn it on, its fine for first 5-10 mints and then power adapter stops working and the laptop runs on battery. So after a while, I have to turn it off to charge the battery.

Power Cord Short > Laptop Worked While Battery Lasted > New Adapter No Power

The original adapter cord for my T61 laptop shorted and sparked right at the base of the laptop connector where the cord had apparently cracked through from too much bending.  Then the laptop worked fine on the battery until it ran out of juice.  There is no indication of power to the laptop on the replacement power adapter cord though.  I verified power at the laptop end of the replacement cord with a multi meter. I think this pretty well isolates the problem to between where the cord plugs in and where the battery power joins the circuit, right?  Would that be in the power supply?  I've read that there is not a "power supply" per se in laptops but that it is integral with the fan kit.  So should I just be ordering a replacement "Thermal device and fan (Integrated)" to fix this problem?  I see in the part list that this is marked as "not to be replaced by the customer".  Is that just a warranty statement, irrelevant outside of warranty, or should I be looking for a good repair shop? I have some experience with computer repair, but have not dealt with any repair shops in years, and have never dug into a laptop myself.  What I think I know to this point, as stated above, is based on a bit of web searching and general experience.  In reality, I'm very unsure of anything I've said regarding diagnosis or next steps.  Please advise. Thank you, James

Dell Laptop Power Supply Fading In and Out--power jack is bad or loose?

I have a Dell 8600 about two years old. Any ideas?

When I plug in the AC adapter, it intermittently fades to the battery as though the plug was pulled out (its not) and of course the screen fades in an out when every time it swithces--it does it every 30 to 60 seconds or so.

I switched to a different AC adapter (I have a Dell 600M with the same AC adapter)-same thing so I know it is something internally.

Charging Battery and powering W530 Laptop with Airline Power and 170W Power Supply

However, with such a large power requirement, want to make sure that I will be able to run and charge the W530 on United Airlines, American Airlines, etc., using the supplied 170 W Power supply...  Please confirm your experience that this will work. Otherwise, using this laptop on long haul flights will not work. 

Can someone please help with this question?

My laptop switches from 'Power Saver' to 'High Performance' power option when I launch a game

Laptop battery light is orange. I hit the power button. lights flash once and wont power on

Compaq laptop wont power, I need an alternate power source

I sent it in for repair once, but it is happening again and I can't find my receipt so they won't honor the warentee. I took it in to Micro Center, and they saudered the power port. I would really like to get some stuff off the hardrive, but to do that I would have to give power to the laptop. Bought it last Feb.

One more thing, the power cord works perfectly.

Same problem here

I am having the same problem with my Presario Laptop x1015. That fixed the problem temporarily, but, two months later it stopped recieving power. If you know of an alternate source please reply or email [email protected]

So my question to everyone is, is there any alternate way I can give the laptop power?

Funny thing is that Compaq told me that this is
not a common problem and tried to blame me!!!! The battery currently doesn't work.

Hp laptop takes 15 minutes to power on after clicking the power button

Hp pavilion dv6-6c43cl

See if your mobo has a power switch on the actual board itself. It has been working perfectly, up until 2 weeks ago. After clicking the power button, 15 minutes later I noticed it just came to life. No fans, no lights nothing.

When i click the power button, nothing happens at all for that duration. The only light on is the power cord button that is always on when i plug it in. Should i just replace the motherboard?

I did replace the power cord, and tried cleaning out the insides, it did nothing. Power it on that way and see if the problem persists

It would not turn on when I clicked the power button. Sometimes it doesn't turn on at all for days, but sometimes I click the power button and it boots within 15-30 minutes.

I have had my Hp laptop for 3 years now. Ps.

Used another manufacturers power adapter, now the laptop doesn't receive power.

Need power tips reference for Kensington laptop power adapter

The tips I got with this Kensington 33197 power adapter have numbers stenciled on them like N3, N5, N19, etc. I need a cross reference for these kinds of numbers. The tips sold on their web site make no mention of the "N" numbers and have numbers like K20059, K20050, etc. Does anyone know of such a reference?

You can also see a complete reference for "N" numbers to all the laptops they support at the above link. Kensington referred me to their telephone tech support; but, there is a language or cultural barrier that prevents their understanding what I need. and there is no cross reference.

Again, no mention of the numbers Kensington uses on their site.

SSD vs Standard HD in Laptop-Battery power, any equal in power consumption?

I was looking at an SSDrive, specifically a Kingston 60GB, for a laptop, but older posts on SSD say they consume more power than standard platter type HD's. Anyone know of a SSD that is more or less equal in power consumption than a standard platter drive?

I'd not go with less than 120 GB with a SSD. 60 GB is not enough at all. That laptop will feel like "The Flash" compared to the slow 5400 rpm drive that most laptops are using.

Overall, I'd say that SSD's are worth it, when it comes to speed.

Equium A60-692 Power supply - laptop doesn't receive any power

Rather than having a hole at the center that a spike on the laptop fits into, its just got a flat piece of metal. Just wondered this was normal and the problem is inside the laptop or if the spike has somehow snapped off and is stuck into the adaptor. It looks like its supposed to be this way but it seems a bit weird... This is quite a common occurrence (check out some of the other posts on these forums).


My Equium A60-692 has stopped receiving any power from the AC adaptor (tho I've metered it and its giving out a good 19v). Unfortunately the solution to this problem is for your nearest Authorised Service Partner to replace the mainboard (quite expensive!) unless you can find someone willing to solder in a new power socket. The flat piece of metal that you describe is the back end of the central pin that has snapped off the inside of the power socket on your notebook.

I've noticed the end of the adaptor (the end that goes into the laptop) is different to normal ones. regards,

Very sorry to be the bearer of such bad tidings.

Y70-70 power supply issues? Laptop cuts out when not on mains power

Checking the system logs in the event viewer I see the following Critical message: The system has rebooted without cleanly shutting down first.

I've recently inherited a lovely Y70-70 touch from my father, and have restored it to factory settings recently. Have I got a duff battery in here?

Unfortunately I'm out of warranty so keen to solve this myself!

This error could be caused if the system stopped responding, crashed, or lost power unexpectedly. Generally online help seems to suggest this is a power supply issue. Are there further diagnostics I can run? However I'm having issues at the moment where it shuts down instantly at random times when not plugged in.
