I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)

If the connector fits (it may not - the older systems use a much larger barrel connector than many of the new ones), AND the power (wattage) is equal or greater, yes.

I have a Toshiba Satellite laptop (circa 2003). I know my laptop battery has been drained for a while and I was almost solely relying on the AC adapter's juice to power my machine. Recently, I lost all power to the laptop. I thought perhaps my battery had finally had it so I bought a new battery. Well, then I couldn't charge my battery, so I bought a new AC adapter. I still have no juice. It looks like the AC adapter is working (the light is on it to show it's getting power) but it's not transferring that power to the machine.

I think it may be a bad connection between the adapter plug and the laptop. I don't know how involved of a fix this is.

Any suggestions on what type of fix might be needed? Is it better to just scrap this laptop and get a new one? Thanks for your help!

First of all Im pretty tech savy so you can talk to me in technical terms. Ive repaired countless computers for many people and I never came across anything like this. This is the problem...
 
Sometimes when I move my laptop or even type there is a complete loss of power. Everything completely shuts off. It happens whether my laptop is plugged in the AC adapter or not. I bought a new battery just in case it was that and its still happening even with the new battery. Event Viewer System logs tell me nothing except that is recovered from an unexpected shutdown. I suspected that maybe there was something loose inside so I took the laptop completely apart and put it back together... still im getting the same loss of power.
 
Now here's a hint that can possible be causing this. When I get this loss of power I cant turn back on my computer unless I unplug the AC adapter and remove the battery for a few seconds and put it back in.
 
Any idea's guys? Ive searched the web and havent found much on this issue nor a resolution so if we do find a solution bleepingcomputer.com might be one of the first to figure it out. If need be give me a better suggestion for the title of this thread so it can be searched for easier. Thanks in advance guys, lets see if we can figure this out.

Hi, my girlfriend in Beijing has an Acer Aspire S3 latop. She bought a new battery for it a while back and told me it was no good. I was in Beijing recently messing around with it and found that actually the battery is fine (lasts for >4 hours) but when unplugged and running on battery power, the laptop often just cuts out suddenly (loss of power). I took the battery out and had a look and cleaned all the connections but they seem fine.

The next part is the strange part and which I hope might give someone a clue as to what's going on...

When it cuts out, it will never restart again unless the mains power cable is plugged back into the laptop. As soon as that's done and the power button is pressed, it starts up again and the cable can be taken out immediately (I mean immediately - you can plug the cable in, push the "power on" button and pull the cable back out in less than a second) and it will start up and run fine on battery again... until the next time it suddenly cuts out without warning.

Because any unsaved data is lost and because the laptop cannot restart without the power adaptor, this very portable and light laptop is now reduced to having to be kept at home all the time and plugged in, which is exactly the opposite of what she bought it for.

Anybody have any idea what the problem could be or suggest some tests that could be done to find out? She took it to a local computer shop but the guys there had no idea.

Thanks in advance for any adv... Read more

Hi, my laptop (HP ProBook 450 G0) won't turn on without the AC adapter although the battery is charged (97%). When the adapter isn't plugged in, the adapter/battery LED (on the left side of the laptop) is flashing really fast (like 20times per sec).

Over the last 2 days I have been having a problem as indicated in the title of this post. The fault has rectified itself 3 times, but again today, it is back to "battery plugged in, not charging." As I am running the laptop (Windows Vista Home Premium; 32 bit) on the adapter without problems, I assume that the adapter itself may not be faulty.
I also have a Dell Inspiron 630M laptop running Windows 7.  Can I safely use that adapter with the Vista laptop, without causing damage to the Vista ?  If it is safe to do so, and the battery on the Vista starts charging, then it would indicate that the Vista adapter/charger has some kind of fault.
Hoping someone can give me some guidance. Thanks.

If the adapter has the same plug and the same or higher power rating, you can swap them.
Check to see whether the 1545 recognizes the AC adapter or whether it shows unknown (F2 at powerup).  If it shows unknown with two different adapters, you have a bad power jack or a bad mainboard.

I have scoured the internet for a similar problem/solution but to no avail. It seems I am the first person in the universe with this problem.

Backstory:

A few months ago, on my ASUS g60 vx laptop, I would notice that while gaming and doing anything really, with the laptop plugged in, it would randomly shift, rapidly, between 'Battery Mode' and 'AC mode' as if I was rapidly plugging and unplugging the AC adapter. It seemed almost as if I shifted it around and made sure not to move it, I could get it to remain in 'Plugged in, charging' mode. So I did that for awhile.

Things got worse and I eventually got a message saying my battery was most likely dead. I got HWMonitor and sure enough, it said the battery was pretty much fried. So I took the battery out completely and just used my laptop plugged in for months with no real problems.

Then Christmas came along and I asked for a battery from my in-laws. They got the exact battery for my laptop, I'm 100% sure of it. I slid the battery into place, it fit perfectly. I turned on my computer and saw the batter had like 33% charge, which I'm assuming it shipped with. Problem is, it wasn't charging the battery. I was still just using the AC adapter power apparently.

For days and days it stayed at exactly 33%. Never would charge. Even if I shut down my computer and left the charging cable in, nothing. So I start my computer, and take OUT the ac adapter. What do you know, it starts draining ... Read more

Hi all

I have an HP 530 laptop (1.6 dual core, 1gb memory, 250gb HDD (was 80gb), windows 7 ultimate 32-bit build 7600 (was vista home basic))

My PC runs like a dream. Recently it started giving me problems though. It dies when it wants to. There's no pattern to it.

Sometimes I'll run it on full battery and it'll hold on for 2 hours. Other times full battery keeps on going for 5 mins and then dies indefinitely. Okay sure, you'll say I should replace the battery, but that's not all.

If I run the PC on AC adapter it can sometimes keep on going without the battery for a while. Other times it'll die after 2 mins. Sometimes it charges the battery full and then keeps on going with the battery the whole day long, other times it discharges a full battery in 20mins and dies. If I unplug the AC adapter for a while and plug it back in it seems to solve all the problems for a short while.

If I delete the AHCPI battery manager in Device manager settings it also solves the problem for a short while. These problems only started when I installed Windows 7.

I have deducted that it could be that:
1. I need to replace the battery.
2. I need to replace the AC adapter.
3. I need to go back to Vista or XP
4. I need a BIOS flash.
5. I need a software fix or setting on Windows 7 of some kind.

Somebody please help!!!

Hi FriedBiltong,

It could be the AC cord or jack. You can easily check it out by moving the cord, usually close to jack. Look at the light, there you can see if power is connected.
Laptops works without battery too, so you can skip that part too.

Hi all,

I have searched and searched for an answer to this problem, but can't seem to find a solution. Maybe someone here has a new idea...

Basically my computer suddenly stopped running on battery power. It had been working just fine until about two weeks ago. Here are the bullet points:

The computer won't turn on with battery installed unless the A/C adapter is also plugged into it. And, once on, the computer will shut down immediately if the A/C plug is pulled out.
The battery is relatively new (less than six months old.)
When pressed, the button on the battery itself indicates the battery is healthy (all lights illuminate, none flashing).
The meter on the computer indicates the new battery is working properly. When left out for a couple days and then put back in, the dell meter shows that it has lost 1% power and goes about charging it then successfully reports 100% charge after a while.
I've tried two old batteries (known bad, just haven't gotten around to taking them to be recycled) while using A/C adapter to see what the battery meter on the computer says... The meter displays an empty battery with a red x at the bottom when either of those is put in.

What I can't understand is why is it only working one direction? The battery will accept a charge from the computer then won't run off that charge later?

Other suggestions I've already tried, but haven't helped:
Verify computer has latest bios update.
Check for bent contacts.... Read more

One year later, I'm back with another problem! I just hope this is the correct forum...

I purchased the laptop I'm using about two years ago. For those two years, I have never removed the battery, but have used AC power nearly always, with the exception of a few quick trips and a couple of hours once every week or two. Initially, the battery lasted about 2 hours on a good day, with Wi-Fi enabled. A few weeks ago, that was reduced, seemingly instantly, to about 5-10 minutes. Upon doing some research (which I should've done when I first got the laptop), I'm pretty certain that the battery is about to kick the bucket.

What worries me, though, is how the laptop seems to be becoming increasingly hotter these past few weeks. Despite the fact that my battery hasn't been involved in any recalls, the paranoid side of me is hesitant about leaving it in for much longer. For now, however, being able to afford a new battery is up in the air (that's a nice way of saying not an option). So, I attempted to remove the battery and use only AC power. About three seconds after I turned the laptop on, it shut off. Upon a second and third try, it wouldn't turn on at all. I let it rest for about 30 minutes and tried again; it lasted long enough to show the Windows XP logo (ten or so seconds) and again shut off. I popped the battery back in, and it turned on without a problem.

So I'm left wondering: what's wrong? Has my laptop become dependent on batte... Read more

A:Laptop won't run on AC power without battery.

I've seen a number of laptops that won't run without the battery, so I'd say that could be normal. A laptop shouldn't damage the battery pack with it plugged in continuously. My wife's laptop has been plugged in most of the time for a year, the battery is just fine. The charging circuit in the laptop should not overcharge the battery.

If the laptop is getting hot, you might consider blowing the dust out of the fans, which is a major reason for overheating of laptops.

A:Gaming Laptop Power Adapter

Yes you can use other Dell adapters.  I even use a 65W for it (came with 12in Latitude E7240 ultrabook). Maybe the reason why they supplied 130W for it is so it can charge the battery faster. Its less portable though, I just kept it in the box untouched.

Also if using anything less than 130W, you can disable the adapter notifications in the BIOS so it won't bug you.

It goes like this: my laptop is normally plugged in, high performance power settings, battery taken out. Every once in a while I put the battery in and use it with normal charge/discharge cycles, power saving settings. Now it somehow happened that when I put the battery in and windows booted up I had no sound whatsoever. Chrome or AIMP2 are not recognized in the volume mixer, and skype notified me that it was unable to access the sound card. When I put it to sleep and then woke it up again the sound came back. I then followed the same steps: shut down windows, booted up, no sound, put it to sleep, woke it up, sound available, a few times and always with the same "results".

Does anyone have any idea what's going on ? This never used to happen before.

A:I have no sound when my laptop is on battery power

Reinstall the sound driver and see if that makes any difference. Sleep and what does or does not work after waking can be driver issues.

How is it booting? From a "cold" boot or booting up from Hibernate. If its booting from Hibernate that can be the cause of the problem (shouldn't be but can be).

I have a Toshiba Satellite laptop running Win XP. It's about 5 years old. The last couple of days, when I have it plugged in, the battery indicator icon acknowledges it's on AC Power, but the battery is still draining and the laptop turns off. I have not changed the power settings at all, but I checked them and all seems fine.

The battery is the original (came with laptop) and the AC adaptor is fairly new (purchased this year). This laptop did have problems with the AC port coming loose, which I fixed. Twice. First by soldering it back onto the motherboard, then by changing it alltogether.

As it stands, when my laptop is plugged in and turned on, the battery drains until it turns off (about an hour). The battery will charge when the laptop is off. The battery charge indicator (led) light turns OFF when I power up the laptop. It turns on again, when I power down. The battery will only charge when the laptop is off.

Is this a battery issue? An AC jack issue? An AC adapter issue? Does anyone have any experience with this? Sorry for length, but I am trying to foresee any questions anyone might have.
 

A:Toshiba Laptop & Battery Power

I would say it is most likely a battery issue if it is original, there is circutry in all laptop batteries that control charging and discharging and for safety. My guess would be start you search here, the battery is probably due for replacing anyways. If the adapter can charge it off then the adapter should be OK.

I have a Compaq Presario R3000 that I've owned for about 1.5 yrs. Several months ago, I noticed that it keeps switching to battery power even when plugged in. It used to happen when there was movement but now it can happen at just about any time. I assume it's a problem in the AC jack but what I want to know is....how much trouble is this to "fix"? Is it a fairly common problem with laptops?
Thanks
 

A:Laptop keeps switching to battery power

It's a very common issue with laptops, and I'd get it corrected BEFORE you end up with this! This is the second of two laptops I've seen in the last year that people ignored the advice to deal with the loose power connection.

As to how difficult it is to fix, that's going to depend on the specific make/model of laptop, and how much disassembly is required to repair/replace the jack.

P.S. Yes, the MB was destroyed and needed to be replaced in both laptops.

A user brought me her laptop (an Acer Aspire 4520) for start up speed issues. While dealing with that I noticed that after shut down, I couldn't power the machine back up by pressing the power button. I have to unplug the power chord and then I can power the machine up. Also, if the machine is in sleep mode the power button doesn't wake it whether it's plugged in or not. You have to unplug it AND pull the battery to bring it back to a state where it will power up.

I've tried every configuration provided to me be Vista to configure the power button behavior in the CP but no luck...

Windows Vista Home Premium 32Bit
AMD Athlon 64x2 TK-53 1.7GHz
1GB RAM
GeForce Nvidia 7000m

Hello every one!I have an HP probook 4530 with upgraded windows 10 -64 bit on it. it was working pretty well since yesterday that i shut it down. (i'm used to hibernating my laptop, but i shut it down once every week) after that i could not make it start. it won't turn on, and the battery power LED on the side of it keeps blinking white for the whole morning!I tried battery, AC power, and both plugged in, but the power button exactly does nothing.i've found a table here with buttons flashing and sequences but neither matched my situation.I have to add that it has recently been warming up a little and had a few lags, which i guessed it's because of the new windows.please help me... i really don't want to hard reset my laptop because i have much data on it.thank you so much...

Hi, please I just upgraded my HP Pavilion 15 Notebook PC to d latest Windows 10 update, and after like 3 days, the system will not power on when I press the power button. But if I remove the battery and power the system through AC, it'll come up.  Also, when I remove the battery and press the power button for like 20 secs, and put the battery back, then the system will power on. Please how do I solve this issue???Thanks NOTE: The system has been on windows 10 for over 9 months, and this started after I updated to the latest windows 10.

My friend's laptop won't turn on. It doesn't start to boot or anything. My first thought is it's either the battery or the A/C adapter but I'm not sure how to check those without having swappable pieces (which I don't have.)
I took the battery out and tried to power on with just the A/C adapter plugged in and same as with the battery in, only thing that happens is the little light with the lightening symbol flashes 3 times. Also the little light where you plug the charger in lights up while the charger is in. Would the laptop power up with just the A/C adapter plugged in and no battery?

This is definately a hardware issue. This laptop will stay on only for a few seconds, and then sometimes for even less. I plug it in press power, it powers up and appears to start working than it suddenly shuts off. I was thinking maybe a power supply, but because I have never changed a laptop power supply, I thought to inquire here to see if anyone might have some advice. All help appreciated!

Thx
 

A:laptop won't hold power, could it be battery??

power supply or battery. Shorted battery could cause the problem but so could a bad PS. You need a voltmeter to tell which.

I've had this a while but never got around to getting ideas on the prob. 4 yr old Toshiba Satellite, Vista, updated OS/drivers... Most of the time it only boots with the power plug removed. After I get the windows loading scroll, I can plug it in and it boots fine. If plugged in while booting, it only gets to maybe the boot loader sequence and then powers off. If I run the boot repair, it may boot with power for a few times but always reverts to booting only without the power plug attached. Tried changing some system power settings with no change. I guess I haven't looked at the CMOS for anything odd. Battery seems to be charging/discharging OK. Boot load script seems normal. Any ideas?
 

A:Laptop only boots on battery power

Sounds like a hardware issue (ie: motherboard and/or power circuitry), not a Windows issue.

I own a acer travelmate 250 Laptop.

When I remove the power cord the screen goes dark, but the laptop is still running, I can open and close the cd tray.

I have also noticed that a beeping noise happens when I move the laptop around.

Any ideas ?
