Computer does not boot when on battery

Q: Computer does not boot when on battery

When on battery, my computer fails to boot. It displays Windows XP logo and loads things but when going into graphics mode it freezes (actually when Windows XP logo disappears it freezes). When on AC Power it boots ok. It looks strange to me. What could be wrong?

P.S.: Safe mode works even when running on battery. If I disconnect AC when XP is already loaded, it doesn't freeze. It works OK at first, but I must test it a little more to be sure. Computer is HP nc8430.

Preferred Solution: Computer does not boot when on battery

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.)

A: Computer does not boot when on battery


If I disconnect AC when XP is already loaded, it doesn't freeze.

On first boot, there is a power drain from the source.
Sounds to me like you need a battery, how old is it?

My battery was dying. I tried calibration, letting the lenovo run just on the battery. It looks like it went down to 0%, then shut off. But it wouldn't charge. It was probably never charging in the first place, always running off the power of the AC.  But I could still boot to AC. So I bought a new battery. It said to calibrate. So I tried that. The battery ran down to maybe 20%, then shut off. But the same result. Laptop will neither boot nor charge the batttery. Again, it will boot just fine with the battery out.  So, what's to be done? Also, I tried to get into the BIOS via F2 and F12, but that doesn't work either.  - Dan

Hello, I noticed about six months ago a memory problem was showing in my mini view on my xps 420. I removed the boards and reseated them and the error went away until now. I ran the diagnostics and followed the error code. It said my cmos battery was bad. I changed the battery and now it will not boot. I ran the repair cd with no luck. Can someone offer some suggestions ? Thanks--- Larry D

A:Computer will not boot after cmos battery.

Remove the CMOS battery.
Unplug the power cord.
Press and hold the power button for 10 seconds to fully drain all residual power.
Put the CMOS battery back in, make sure you put it in correctly.
Plug in the power cord.
Power up.

You should get a CMOS configuration error message. Press F2 to go into Setup, load defaults, set date and time and boot options then see if it will boot.

Safe mode works even when running on battery. If I disconnect AC when XP is already loaded, it doesn't freeze. Computer is HP nc8430.

I already tried to replace battery but the problem still exists.

Is there any chance to get a log of boot activity to see what is the problem? Maybe you have better idea?

I tried some more things. I tried restoring OS to an earlier date with System Restore. Suddenly all started to working even on battery. But after few hours problem was back. I tried another System Restore point. It was the same. At first OK, then problems. I really don't know anymore what is going on. I don't want to format computer because it is my work computer and I can't lose 2 days to install everything back up.

HELP! Computer won't boot! Tried everything!

Ok so this is my set up:

edit: a floppy and dvd burning drive

Ok and the problem is:

I installed a ripped off ****ty version of XP. Never really worked splendidly.
I changed somehting in the bios, i had no idea what it was, i'm stupid for doing so i realise. it was something to do with speed, it was at about 100mhz and i changed it to 200mhz. also note, i had the "bios virus alert thing" ON.
the next few boots were dodgy and it only booted up every second or third attempt. if it didnt boot up it wouldnt boot and just went beep (long beeps and repeated -in no code) this worked for 4 boots before it never booted again.
it just beeped.
until i moved the jumpers on the 3 pins from the two pins closest to the battery position to the furthest two. and turned the pc on. it didnt beep. the monitor didnt respond and but it seemed to be turned on (the cpu fan was going and a green LED on the mobo was on). i then turned the power off. and stuck the jumper back on the original pins and turned it back on hoping the BIOS would be reset but the beeping sequence continued and nothing seemed to start. So then i took out the battery for over half an hour... then put it back in. (with the jumper still on the original pins- nb: the... Read more

A:HELP! Computer won't boot! BIOS? Reset it. CMOS Battery? In and Outed it. HELP!

The Athlon XP 2600 that runs at 1917MHz runs on an FSB of 166MHz and has a clock multiplier of 11.5 (166 X 11.5 = 1909Mhz).

So if you have a system bus setting of 200MHz and the clock multiplier is set a 11.5, you were running it at 2300MHz, which is seriously overclocking it.

The processor might not have been up to that much overclocking and died.

Find out what BIOS settings do before you change them!

All, Very strange thing going on, and I've not seen it on these forums, so here I go. Turn on laptop, the HP screen appears, and about 20 minutes later, Windows starts loading.Turn off laptop, pull the battery, turn on the laptop, and Windows starts loading within 10 seconds (normal). When the battery is in, EVERYTHING takes 15-20 minutes to start.  If I select F2 for settings, it takes that long.  If I hit F10 (or possibly F8), same delay.      If I take the battery out, it works perfectly. So....I of course assume bad battery......but I've never seen this type of behavoir in ANY computer previously. Any suggestions?HP G62-340US Notebook Windows 7 Home PremiumNo error message and no changes made to system. Thanks Donlen

In cooperation with various government regulatory agencies, HP has announced an expansion of its June 2016 worldwide voluntary safety recall and replacement program for certain notebook batteries. Additional batteries are affected. The affected batteries have the potential to overheat, posing a fire and burn hazard to customers.
Because affected batteries pose a fire and burn hazard, it is essential to recheck your battery even if you did so previously and were told that you were not affected. Note: if you have already received a replacement battery, you are not affected by this expansion.
To recheck your battery, and order a replacement if eligible, go to the HP Battery Recall website at: http://www.HP.com/go/batteryprogram2016

After my friend's laptop wouldn't run on battery power OR charge the battery I tried many "fixes."
Shockingly none worked that I found.
Only one thing worked for me to my surprise.
A last ditch effort was to open up the laptop (sony pcg-81114L) and disconnect the cmos battery for a few minutes to reset the CMOS.
To my surprise, when powered on, the battery instantly showed it was charging AND when removing the power plug the battery POWERS the laptop now! (and I'd thought I was wasting my time.)
Worked with an off brand battery also.
Many times this has saved many computers that have odd "unsolvable" things wrong with them.
Surely someone else has done this also but I haven't seen it posted anywhere to my knowledge.
Thank GOD for bringing the idea to remembrance!

I have an older HP Omnibook 6000 upgraded to 512 of memory running XP with service pack 3, using an airlink card for wireless and Trend for security.

I tried to clean up some disk space and must have deleted something the OS needs. Here is what happens:.

(1) Plugged in, everything is perfect.

(2) When I unplug and try to go to battery, the screen/mouse/keyboard interface freezes. My airlink card stays green (active) and I can still hear some whirring sounds. The hard drive access light goes off.

(3) On battery, the system boots and runs fine in SAFE mode.

(4) When I try a normal boot unplugged, here is how far I get:
<F2> ... screen comes up -- Windows XP logo and blue "activity bar" come up, hard drive access light is working, airlink card green light comes on -- Black screen, which is usual just before the login window, but instead of login window the machine acts as in (2) above.

A:Won't Boot on Battery

Go into safe mode and go into msconfig and open the start up tab. What do you have in there? I would bet a lot of apps initializing on boot up. Keep only the apps you need like antivirus, firewall if there is one and any app you feel you need, but you only really need the above mentioned.

Here's a strange one:

On my Thinkpad R31, if it is plugged into an outlet, XP hangs on the splash screen, it even hangs on all safe modes. If I unplug it and let it boot off the battery, it boots perfectly fine. Once it's booted, I can run it off the adapter without a problem. The adapter charges the battery fine, and the battery holds a charge for a little over three hours of light use (web browsing, word processing).

Any ideas as to why it does this? I've tested it several times and it always boots without a flaw off the battery, but never off the adapter. I don't even know what to begin with here its so strange.



BTW, it stops at mup.sys when booting in safe mode.

A:XP will only boot on battery power

Could be the power supply causing it have you tried another power supply?

Hello all,
I'm having an odd problem with a Tecra A6 I picked up recently to refurb in that it will not boot with a battery only: It boots only when the AC/Mains is also connected, however it will finish booting on battery alone (and runs fine) with the AC cord removed soon after pressing the power button. It's just on battery alone that I get no response from pressing the power on button (so the mains has to be attached at that very first stage or I get nothing at all).

Now I'm wondering if maybe its the voltage of the battery? It seems there are 2 options for this model, one at 10.8v and the other at 11.1v. With Windows loaded and Hardware Monitor running it reports the battery is at 0% wear level and charges up fully (so I do not think the battery is faulty), however it states the battery is running at *11.1v,* but the battery installed is in fact the *10.8v* model. Could that be preventing power on with battery only?

Further info on the model I have:
Tecra A6 PTA60E-0EJ013EN
CPU: Intel Core 2 Duo T7200 2.0 Ghz
2 Gb Ram.

Thanks in advance for any help on this one. Main thing I'd like to know is if I do need an 11.1v battery to run this model properly (and get it to power on) on battery alone. If the voltage makes no difference then I guess it must be an odd motherboard issue and I need not bother buying a new battery.

A:Tecra A6 does not boot with Battery only

Update on this one:

It appears the battery is likely faulty: I didn't leave it to run on battery only for long for initial tests so I thought I'd run it down, recharge, then see if that helps. I turned off all the power save settings then left it without the AC attached, however, in spite of reporting a full charge before the AC was removed ,the laptop switched itself off after only 5 minutes or so. On reboot (with AC attached again) the battery is reported as flat!

I have it on charge right now but the battery is *not* getting warm (it did the first time I installed it) so I figure either the battery or the mainboard is reporting the charge level wrong (this is a used battery btw, though it is a genuine Toshiba model, not a dodgy oem import).

Will have to buy another battery and see if the same thing happens (I'll know then if it's the motherboard), but in the meantime if anyone can let me know if the voltage does matter I would appreciate it.

I'm posing for my Mom's computer system. This is what she has done so far to it.
I have Windows XP Professional Verison. It's a HP System. I put in a new Fan Motor and a new Lithium Battery and now it will not boot. It powers on and freezes up. Though if I turn it off and unplug then pop battery out and then put the same battery back in it will boot up to the setup screen. If I tell it to reset it's settings, it then will fully boot up and I can do whatever I want on my system. All my info is there and data. Now it will run until I shut it down. But after a shut down or restart it will not come back up. I even tried a new battery from the store thinking maybe the battery I got was bad or something. I appreciate any help anyone could give me. I'm loosing my mind.

I recently got this computer from a friend so I have no idea how long this has been going on. Probably why he got rid of it. I will plug in the power cord and try to boot with the battery in and nothing will happen. If I reach under the laptop and remove the battery and then try to boot up it comes on like normal. I can then put the battery back in but it makes no difference after that. The battery is completely dead. Does anyone know if this is a common problem with a bad battery or what. The computer is a Dell Latitude D630. If I knew that putting a good new battery in it would fix it I would without hesitation I just need to know if that is the problem or is it another glitch. If anyone knows the answer I would appreciate if they would pass it on. Thanks

I replaced my laptop battery and once I installed the battery pack with a non-Toshiba compatible battery my laptop won't boot from the battery alone (Tecra S10-114) After the boot was done by AC adaptor (without fitting the battery), I installed it and the OS (WIN7 Professional) recognize and charge the battery regularly.

I can unplug the AC and the laptop working very well until there is enough battery power. Battery specs are almost similar than original (10.8V 5100mAh - PA3588U 1BRS) - 10.8V 5200mAh replacement for Toshiba battery PA3588U-1BRS, PA3356U, etc.

Hey, I really need help. I'm having problems with my laptop. It's a dell inspiron 7559 and was bought around January. Recently I have seen that the battery has no longer been as hot as it used to be when I first started using it. Along with the sleeve on the tip of the screen power adapter (below the part where the adapter lights up) has started to come off, exposing the wires. The battery has continually dropped down its percentage rate ever since I bought it, and it won't go back up. It is currently at 0% battery life and it says when you highlight over the battery icon ( plugged in, not charging). It also happens to show the BIO setup when I start the computer and shows that the batteries wattage and type cannot be determined. In the BIOS setup, the ac adapter type is unknown. The battery has not been through any harsh conditions along with the laptop. I have tried removing the battery, starting up the computer with the ac adapter (which is 130 watts), then adding the battery back, and ac adapter, then turning it on, but it had no effects. If I remove my ac adapter while my computer is on ,it instantly turns off. If someone can support me with this issue, it would be gladly appreciated. Thanks.

A:T470s BATTERY 1 drains to 5%, BATTERY 2 stays at 100% (BATTERY PRIORITY)

Sorry  but see below post.  Basically you cant set discharge order.  The laptop checks battery wear and bases discharge order on that.  Many people including myself have asked for a BIOS switch or at least an option on discharge order but nothing has happened so far and I dont think its going to happen either.  I do not speak for Lenovo..

Hi guys. I have a T470 and after the latest Windows update I encountered a battery naming issue.

But after the update I noticed the order has changed to battery 0, battery 1 (attached pic below) Yeah yeah, I understand arrays start at zero but what is that? I was just wondering is it just me or you guys have the same situation going on with your batteries? Is there a way to change the order back to "normal"? .

A:Tecra M10 freezes during boot with new OEM battery

> I bought a OEM battery for my tecra and now the laptop freezes during boot (the screen stays black with an underscore blinking) with the battery plugged in.

In most cases the blinking underscore is related to faulty HDD or RAM issue.
In my case the HDD was faulty and therefore I got similar notebook symptom.

I?m not quite sure where the connection between blinking underscore and the new battery is but the whole computer world is really strange sometimes and many strange things can happen? so maybe the new battery is faulty?

Did you notice this issue with the old battery?
If not, then I would recommend testing other battery? maybe it helps?

I'm suddenly experiencing this problem. I'm unable to boot my laptop from my battery. But if I connect the power chord, I'm able to start it. There is no problem with restart, hibernate and other options on battery though. I've also installed batterycare to check the battery condition. It shows no problem with battery condition. Can anyone help me out with this problem?

A:Unable to boot from battery power

Do you have access to a digital multimeter my friend as it will show you if the thing is ok on voltage or not .

Having said that it might e holding a voltage but no current capabilities - how old is it? as Lithium batteries degrade from the day they are manufactured mate. On average that can be around three years. I personally would not rely on the battery health readout an actual check is best.

By he way depending on the make and contact set up check out too if there is any debris down inside those slots either in the battery (usual) or the machine.

I thought I had this problem licked, but obviously I don't. I noticed tonight, when the battery was allowed to go completely dead, I plugged the machine into AC - and when it booted up, it did so but not to where I was before. Instead, it just boots up to Windows.
In the Power Options / Critical Battery Action, I have it set for Hibernate (for batter) and in the Low Battery Option, I have Do Nothing. This is where the Default takes me and it worked a couple times, but the last couple times it is not.

Any idea as to what might help me overcome this unhappy snag?

A:Battery goes dead - system does not boot up to where it was before

It could be the battery itself is worn or faulty. Usually when it goes into hibernate it saves enough power to keep files in memory. But if you lose power completly it will just shut off.

You say you replaced the battery, was the replacement brand new ?

I have a older 14r 5420 that i would like to get working for my folks. It was sitting in storage for a year not used. the last owner said the battery was not able to hold much of a charge (that was a year ago), if any, and that the keyboard was broken last time he used it. (which is the reason he stopped using it)
I plugged it in, went through the process of burning off the "flea power" or what ever it is. But the thing will not power on. Its like no power is getting to the motherboard at all. No beeps or lights outside of the green light on a power bar. Can a fried or dead battery cause this? its been plugged in for about 2 hours as i write this. I can replace the keyboard if i can get it working. But i don't want to go to the expense, if not. 
Is there a way to test it? make sure the battery is getting enough power? test to see if its outputting enough power? Is the laptop normally able to boot without the battery in? (im thinking not)
Any help would be great!

A:14r 5420 Can a dead battery cause it to not boot?

Unplug, remove the battery and hold the power button for 30 sec.  Remove and reinstall both memory modules and the hard drive.
Verify that the LED on the AC adpater is ON before you plug in the notebook end.  If it's not, replace it with a new OEM Dell AC adapter.
Power up on AC only - if it will but won't with the battery installed, the battery is bad.
If that doesn't get the system going, the mainboard is bad.

I have a HP Pavillion Slimline S3600f and I'm running Windows Vista 64 bit. Couple of things happened first I attempted to install new memory. Well my board did not like it I was told that the memory was compatible with my system. Next, my daughter stuck her flash drive in my system kid didn't even know where to stick it, should have stuck it in her ear first because she had no clue as to what she was doing. don't they study first, nope. The next day my system would not boot. Did a little reading and took out the CMOS battery which allowed me to go into setup I changed the time and clock in the BIOS f10 save and exit, and it did not save it back to Jan. 2007. In order to get back into the system I had to turn off the system press esc to get into Load Boot which brings me to a screen where I select the hard drive. It then brings up screen Default Bios settings have been loaded due to BIOS update or checksum issue press f10 to enter setup otherwise allow the PC to continue. I let it continue and windows comes up but it takes about 10 minutes. I'm a little stuck here, do I have a major problem or something that can be fixed. I was reading and could use some help here I was reading about the ROM BIOS don't know what else to do at this point. I ran Hardware Diagnostic Tool and everything passed except the Smarshort self test took about 13 min. put it passed. I also ran a Sysem memory test and everything passed. Help me please!

A:System will not boot with CMOS battery

The system will not be able to hold BIOS settings unless the battery is in.

You mentioned 2 things that happened to the computer but not what the results were. Where did she put the drive? Did the system work after you tried the wrong RAM? Did either of these things cause damage, and if so, what damage? Did you check all your connections inside after changing the RAM sticks (things get loosened very often)?

Are you saying that Windows actually boots OK, though slow?

On a Dell Optiplex GX620 running XP Pro SP3 I am getting a Found New Hardware dialog box just after booting into windows that states that there was a problem installing hardware and indicates that it's a battery. The specific error is that "The data is invalid". I looked in the Device Manager and it shows a battery with and Unknown Device and yellow triangle on the icon. I uninstalled it and rebooted. Now no battery shows in Device Manager but still getting that Found New Hardware dialog box with "The data is invalid" error message. Any ideas?

A:Desktop PC trying to find a battery on boot

That may have a proprietary driver. Did you check the drivers at the Dell site? It may not be a specific battery driver, but a chipset or other one that includes it.

Hi, Got an issue with a ProBook 470 G3 not booting properly. The battery is charged but the Probook won't boot with the battery in the laptop: it only boots without the battery but with the powercable.  Once booted I can plug the battery in and remove the powercable and it keeps running. But as soon as I want to boot again I need to remove the battery and put the cable back in. It's a brand new laptop and the battery has been replaced by the dealer once already but the issue remains.

Since the last few weeks, my computer was not able to start properly. When i press the start button, my hp laptop just gets stuck at the white HP logo screen. If i get lucky it gets pass the logo in around 15min then start up normally.
It seems that there is something wrong with the power. When i start my laptop with only the battery, it seems that this situation occurs more often and when i plug in the AC adapter (and wait for a few minutes) it starts up normally. HOWEVER, today, it did not work. I restarted my computer around 5 times with ONLY the AC adapter and finally got through the process.

It seems that the hard drive is not working during the startup. When i had the option to use startup repair or boot windows normally, it took around 20 seconds for the computer to respond when i chose it.

I Really want to solve this problem, i want to bring my laptop out of my home without my AC adapter.

Thank you

A:Long time boot because of battery?

I've seen something similar when the dvd drive is funky. Pop it out and give it another try.

If that doesn't help, enlist the help of a friend's computer and download the offline Seatools iso. Burn it to cd and boot up with it on your laptop and do all the tests that are not destructive.

First off I have a IBUYPOWER 101 batalion turbo laptop or its also a uniwill 259en1 notebook as well. Just recently (past 3-4 months) whenever I restart my computer and it gets to the login screen it instantly shuts down and begins the startup again, and this process continues. However, when I remove the power cord (running on battery) it starts up fine. So basically i have to remove the power cord until it reaches the login screen and then i reconnect it. What would be causing this? Hardware? Software? Thanks for your input everyone.

A:Laptop wont boot with ac on, but only with battery.

Have you got a multimeter to check the voltage from the power supply?
The output voltage should be listed in your power supply.
If your power plugs directly in to the laptop (without a transformer then your on board power supply may be going bad.

I was working on an old computer for my son today. I forgot my password so I removed the battery to reset everything. When I replaced it the screen stays black. Everything appears to be operating on the inside of the case but my keyboard will not light up and my monitor stays in standby mode. Prior to removing the battery the computer ran fine.

A:failed boot after removing battery

That indicates that the computer is not even reaching the POST stage of booting from the BIOS.

What else might you have disturbed while removing the CMOS battery?
Is there a tamper switch on the case that has been triggered? (a "feature" of a few older PCs)?

Is the battery reinstalled in the right manner?

Hello. I am having some frustrating issues with PC boot up. The mobo is Intel DB65AL.

Here's what's happening:

Pressing the power button, I can see PC parts turn on, fans are spinning and all, however it takes ~10 seconds (monitor's LED is blinking as if it's not receiving anything) for it to actually start booting up and the BIOS UI to appear.
After it boots up, there is no internet connection.
Restarting the PC, it again takes ~10 seconds to start booting up.
Halfway there PC restarts itself.
~10 second wait. PC finally boots up, there's internet connection and everything's fine.
Shutting down the PC brings me back to point 1, restarting - to point 3.
This started when my GPU started dying and a friend came over with his R9 270 to test if it's really GPU or something else causing problems. With R9, PC wouldn't even boot up. The friend then decided to try resetting the BIOS by taking the CMOS battery out. He didn't exactly know how to safely remove it from the slot, but with a little (really little, I was watching) force he succeeded. Putting it back, nothing changed. PC with R9 in place wouldn't boot up. I've added my own GPU back and at least the PC booted up normally.
Anyway I'm on an integrated GPU right now. After reboot I heard some sound in the case and was greeted with a message in BIOS: "CMOS battery failure". However PC would still boot up normally after that. I then tried to re-seat the batter... Read more

A:Weird Boot Up (Battery Issue?)

To test the Cmos battery go into the Bios and check the date and time are correct. Then switch the computer off and disconnect the power lead from the wall or PC end. Leave it like that for about 15 minutes then switch it back on and go straight into the Bios and check if the date and time are still correct. If they are the battery is connected and working ok, if not it isn't.

If the battery is working ok I would guess the switching on problem is caused by your PSU being overworked when powering the R9 270.

Please run this and paste the output into your next reply :- http://static.techguy.org/download/SysInfo.exe
Please add the make and model of your PSU as well, you may have to read this of the PSU case.

I have a Toshiba laptop model S70-BBT2N23 which I purchased last April. The laptop works fine with no problems.

I decided to buy an extra battery to use as a backup. When I installed the battery, the computer would not boot up, even with the AC plugged in. If I remove the battery or put the original battery back in, all works fine. I initially thought this was a battery problem, so I exchanged the battery for a replacement and got the same result. These were aftermarket batteries, so I then bought a Toshiba branded battery which appeared to be exactly the same as the original battery - and I again got the same result. In every case, the laptop will not boot up with the replacement battery and just flashes the power light, even with the AC plugged in. Put the original battery in (with or without AC) or just run on AC and all works fine.

Any ideas?

A:Laptop won't boot with any replacement battery

That's crazy.....I would put in a support ticket to Toshiba and see what their techs say about that. Aftermarket or OEM replacement battery should work as the old OEM battery does......baffling to say the least.

I have a Yoga 910 that will not boot, aparently due to a dead battery.  The battery has not been charging well for some time.  I thought it was the power adapter, so I replaced that and all was well for a couple of weeks.  But today the battery drained all the way and it will not boot.  When plugged in, the amber LED flashes.  When I press the power button, the LED on the power button comes on, keyboard light sup and the Lenovo logo screen comes up briefly, but then the system shuts down.  Based on another thread I tried unplugging it and holding down the power button for 60 seconds.  That did not have any effect - it is still behaving the same.  If I try to power it on without the power adapter connected, nothing happens - no LEDs on the power button or anything. Even if the battery is totally dead, shouldn't the laptop run with the power adapter plugged in?  I am using a standard Lenovo 45W USB-C power adapter.  I tried using a different (non-Lenovo) adapter, with the same results.  Would it run off AC power if I had a higher wattage adapter? I need to get it to boot for at least a few minutes so I can retrieve my daughter's homework off it.  After that I can take my time and get a replacement battery or whatever.  But I am amazed I can't get it to boot at all.  I used to operate ThinkPads with the battery totally removed and they ran fine.  Would it work if I remove the battery completely?...

My XPS M1710 is running Vista and is displaying this message when trying to boot up:
WARNING: The battery attached can not power the system. The system will not boot with this battery plugged in. Press F1 to shutdown the system.
The message still appears even if I plug in the charger, after a new genuine battery , a new hard drive and a fresh installation of the operating system. The laptop will only boot up if I remove the battery.
If I insert the battery after the boot up and unplug the charger the laptop will function normally for over 2 hours till the battery goes down.
I wonder if there is some setting in the BIOS or somewhere that can be changed to fix this? Can anyone help?

A:XPS M1710 will not boot up with the battery installed
