hal.dll error after successful boot, CMOS battery flat

Q: hal.dll error after successful boot, CMOS battery flat

Hi there, firstly just want to say thank you to this forum - I'm newly registered but have followed a lot of advice here to fix machines in the past. Registering now as I need some advice of my own! Sorry for the long post, I just want to be as clear as possibly as I the computer is at my parents' house and my dad might need to run some tasks for me.
In summary:
My computer won't boot XP due to a missing/corrupted hal.dll error, which appeared after a successful boot. The machine hadn't been run for few years and the CMOS battery was flat. After setting the clock in bios it booted to XP fine, then produced error after 5mins. Puppy Linux mounted the drive but was too unresponsive to actually use. Ubuntu live cd won't mount the hard drives, giving exit code 13. My goal now is data recovery - I'll probably try to reinstall Windows or dual boot Lubuntu afterwards.
More details:
I've read lots about my error but nothing given how it appeared I need some advice as I don't want to damage the drive (I just want to recover the data before setting up a new dual boot config). Further details and steps below just in case it helps to isolate the issue, as I've read some people saying that the problem won't be with hal.dll but the boot.ini file (which I'd find odd as it did boot just like it used to). Additionally, whilst the error message said windows could not start, the message was the same when it did boot as well as when it couldn't. Is it just that the drive is still mounted in windows or some of the file system is corrupted?
1. Powered on/off few times trying to get keyboard working
2. Reset clock in bios
3. Booted to windows xp from hdd
4. Logged in, no issues
5. After loading desktop couple of error dialogs appeared (I think i tried clicking the taskbar afterwards)
6. Went away for 5 mins, came back and was at a command prompt with hal.dll error
7. Powered off machine, tried rebooting, same error
8. Tried booting Precise Puppy DVD to mount hdd, booted fine although was running impossibly slow with hdd
9. Puppy gave a warning about ntfs-3 when trying to mount. After about 3 minutes it started showing a few folders inc Windows on the "ACER" drive.
10. The system was so unresponsive I gave up, puppy just didn't respond to anything. I tried clicking to unmount etc but I wasn't getting any feedback, so I (probably impatiently) powered off to try a different DVD
11. Booted into Ubuntu 12.10 live DVD with no issues (have used the DVD before) and got a more responsive desktop
12. Tried to mount both partitions, got the same error message with mount exit code 13
13. Rebooted (from the Ubuntu menu), hitting F8 to get boot options. I thought that checkdisk was accessible from here but my memory failed me 😅
14. Tried XP safe mode, wouldn't boot, powered off
15. Tried checking bios for any other disk checking tools, gave up
What's the best course of action here?
A. Try and run chkdsk from the recovery console?
B. Try and reinstall the hal.dll file from XP cd? I think i only have a copy of XP Pro, but I expect the file is the same?
C. Use some other tool like Testdisk to recover data?
D. Use a Windows 7 DVD to do the notepad/open/explorer trick to copy/paste files?
E. Something else?!
Basically my goal is to backup the data and then worry about getting the machine rubbing again another time. Really wish I had proper backups of this machine!
Thanks in advance.
Machine details:
* Acer Aspire E300 desktop pc
* Windows XP Home SP3
* One hard drive partitioned (by acer) into two: ACER (C:\) and ACERDATA D:\)
* No hardware installed except for a Soundblaster Audigy 2. On-board AC97 disabled in bios, sound was working when it booted

NTFS is either inconsistent,
Error mounting: mount exited with exit 13: ntfs_attr_pread_i: ntfs_pread failed: Input/output error
Failed to read NTFS $Bitmap: Input/output error
NTFS is either inconsistent, or there is a hardware fault, or it's a SoftRAID/FakeRAID hardware. In the first case run chkdsk /f on Windows then reboot into Windows twice. The usage of the /f parameter is very important! If the device is a SoftRAID/FakeRAID then first activate it and mount a different device under the /dev/mapper/ directory, (e.g.
/dev/mapper/nvidia_eahaabcc1). Please see the 'dmraid' documentation
for more details.
Windows error:
Windows could not start because the following file is missing or corrupt:
<Windows root>\system32\hal.dll.
Please re-install a copy of the above file.

Preferred Solution: hal.dll error after successful boot, CMOS battery flat

I recommend downloading and running DRP. It's a recovery tool that has been proven to recover files that most other programs have no luck with. I've even recovered files from freshly formatted or partitioned drives.

You can download it direct from this link http://goo.gl/v51TwD. (This link will automatically start a download of DRP that you can save to your computer.)

A: hal.dll error after successful boot, CMOS battery flat

hal.dll is a very system specific file that is chosen from a selection of identically named files in the installer, especially for your setup, and then modified on on first run. You cannot replace hal.dll. An error with this file is one of the few instances where a reinstall is the only option.
Do not run chkdsk, it's likely to scramble your drive if it's not mounting properly and if there is a physical problem with the disk you may cause it to fail completely. Mounting it on another running Windows system and then copying your data over is another option that is worthwhile as Windows can sometimes handle NTFS better than Linux.
Failing that... you are right adding Testdisk to your list of options. That would be the next step..

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.

My Dell dimension 4300 will not power up..ONLY when the cmos battery is installed!! When I take out the battery it powers up ok. I replaced the battery and the same problem. I did not mess with the jumpers on the mobo. Just removed the battery for a day and the power cable was detached so no power was available. Any Ideas what may be causing this?

A:no boot with cmos battery installed

Exactly how far into the boot does it get with the battery installed ?
Does it show a key to press to get into the Bios ?

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

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?

I apologize for the length of my post, but I have gone thru several steps in trying to solve my problem.
I turned my Win-7 PC on and got the error message "CMOS/GPNU checksum bad".

Research suggested one cause might be the CMOS battery (#2032), which I replaced. I entered BIOS and everything looked good except for the date/time, which I reset. I then rebooted and got the error message "invalid partition table". At that point I inserted my Win-7 installation DVD to try and repair my installation. Unfortunately, no OS was found on the hard drive. So I selected the option to re-image (using a fairly recent system image stored on an external drive). After about an hour, the process was finished and I got the message that the restore was successful. A system restart was then required, but it was not successful....I once again got the error message "invalid partition table".

I also got the message that the reason that the startup repair was not successful was because 'no OS found on disk".

Any help/advice would be appreciated. At last resort I could try a complete reinstall of Win-7 but I would probably lose a lot of data that I had been backing up via the system image.

A:Can't boot or repair Win 7 after replacing CMOS battery

Hi Durango,

I would try the following:

Turn off the laptop/desktop
Unplug the External USB HDD (and all other USB devices)
Make sure ALL media bays (SD Card reader and DVD drive) are empty
Go into the BIOS config on boot up, and configure the boot sequence to leave off everything except Internal HDD, and CD/DVD (turn off the USB and secondary (if any exists) HDD from the boot sequence)
Reboot - and hopefully windows should resume without any error message.

i have a satellite c50-b-14d a few days ago the hard drive gave up on me and i replaced it. exact same model. i installed windows 7 as i dislike windows 8 lol, started updating it fine then half way through updating i go to boot the laptop and it comes up with ---rtc battery is low , press enter to set time and date---- so i go in and set the date and time and hit exit saving changes, laptop starts i see the toshiba sign for 2 seconds and it turns off.

surely its not the rtc battery being low that is stopping it booting, i thought it might be the charger so i got a new one and still have the same problem, any help would be appreciated please.

Hello all,
I was trying to install Windows 7 Starter from a bootable USB and I got this same error. Upon reading this threat, I found the solution. In the boot-up list in your BIOS menu, you have to remove the Atheros boot agent / LAN from the list.
It will then boot to whichever boot-ready device you've got.
I know this doesn't solve the entire issue of this threat, but at least it'll remove this pesky error.

I have an Optiplex 755 USFF desktop computer that required the cmos battery to be replaced. After replacement the computer will not boot. It brings up the start windows menu, sasfe mode, safe mode with networking, safe mode command prompt, last know good configuration and start normally. Any option will bring up the WIndows XP load screen and then the computer re-boots right back to the start screen. One big loop. I can get the hard drive to boot in an Optiplex GX280 without issue. I was told the motherboard needs to be replaced but I switched system units and the same thing happens with this hard drive.
I've tried to reinstall the OS and get all the way to "starting windows" and then the blue screen of death stop error 0x0000007B (0xF7A10524, 0xC0000034, 0x00000000, 0x00000000). The computer is WIndows XP SP3, 1GB ram with 80 GB hard drive. It appears that setup doesn't reconize the hard drive.
Any help would be appreciated. 

A:Optiplex 755 USFF will not boot after changing cmos battery

After several hours of experimenting, I finally figured out the correct BIOS settings in order to get the computer to boot. There are three BIOS settings that have to be changed or checked from default settings to get it to work. SATA 0 must be on, SATA operations must be changed from AHCI to ATA, and under modular bay the default "on" setting must be changed to IDE. Save the settings and the computer boots right up.

Hello, I replaced the cmos battery today because the last one died out. After booting the computer, however, the following error appears: "Reboot and Select proper Boot device or Insert Boot Media in selected Boot device". This error didn't show up before and I didn't touch any of the hard drive cables. Any idea on how to fix this? Thank you.

A:Error after changing CMOS battery

Make sure the Power Plug from the PSU to the back of the HDD is plugged in tight as well as the SATA Data cable to the back of the HDD and the motherboard and was not accidentally unplugged during the battery change.
Start computer and boot into Setup (Bios) set the Bios to Defaults, usually by pressing the F5 key. On the Main screen of the Bios it should show all of your drives. Is your HDD listed? If it is, Go to the Boot tab of the Bios, if it's not already, move the HDD to First Boot Device. Save and Exit.

I located an older mobo, an Explorer III motherboard (screen says on boot up: Award Modular Bios v4.51pg followed by P51430VX/280DM Xplorer III Bios v1.3s 9/7/97). The board appears to function fine but CMOS isn't holding the setup config. It loads the Defaults (cpu to 75MHz when it should report the value I set it at = 166MHz) The cpu is a Pentium-S @166Mhz. Since the battery holder was broken, I replaced it & added new 3V battery. The battery measures ~3.5 V but the "Error on checksum" still appears & I still get reports for "CMOS Battery Failed". So, re-heated and also removed & re-soldered the holder conn's (about 20x's) but still get the same result each time. How do I buzz out the connector? I have No diagrams of board. I would check the board with a meter if I knew where the check points were located. This board (as said in your file) performs an "auto detect" via SpeedEasy and is worth keeping since it has a low level format capability.

HELP! Computer won't boot! Tried everything!

Ok so this is my set up:

Asus A7N8X-X motherboard

sapphire radeon 9600xt 265mb GFX

amd athlon 2600+ cpu (1.91ghz)

80gb HD (just some cheap one- i forget brand, perhaps seagate)

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!

I am readying an old PC I built (686 Cyrix 200 Mhz) to give to a brother who has never had or tried a computer but is expressing some curiosity. Long story short I discovered several issues when I powered up this PC to ready it for a car ride to Florida that is leaving soon.
1. CMOS battery/Checksum error, removed old 2032 battery
2. I also removed a non functioning primary slave Seagate HD
3. Installed new battery
4. On reboot HD was not detected, auto and user defined HD did not work, system kept reverting to 9/1/1996 date. CMOS/Checksum errors continue despite new battery. Also moved jumper on HD to reflect single drive status.
5. Swapped power supply from CD to primary master HD (Western Digital) resulting in HD being detected. Used a different power supply cable for CD resulting in CD but no HD. Removed jumper from HD completely and tried a 3rd source for power to CD which worked, HD and CD detected, continued CMOS/Checksum errors mean Plug and Play enabling in CMOS is not being retained and must be enabled through setup to continue booting.

AND with the cover off and the tight fit of swapping things in a desktop I also noticed that the CPU fan is not spinning. I am not sure when this happened, I was feeling heat on my hand all along as I manipulated cables. Good thing the cover is off. This fan is attached to the power cable I have attached to HD which meanes that it used to be piggybacking off CD drive not HD. My motherboard manual (FIC PA-2006) indicates th... Read more

A:CMOS/Checksum error continues after battery replacement

Sounds quite confusing all the things you tried.

Checklist ...

1. Is the replacement battery *fresh* (3 volts for CR2032)?
2. Reset CMOS (via jumper).
3. Go through all bios settings and check they are suitable.
a) Try selecting LOAD BIOS DEFAULTS setting first.
b) PnP Configuration Setup\Reset Configuration Data
- Set this to 'Enabled'.
4. Try reseating all components and connections.

If all else fails then its perhaps the mainboard could have been damaged by 'static' if adequate precausions were'nt taken while working on it.:blush:

I have two identical Dell XPS 8700 for my kids. I got them around May 2015.  They use them mainly for steam games and Office 2016.Both running the Windows 10 AU.Today on one of them, by son said a message popped up and asked to stop a service and he clicked yes. Then all there was, was a gray screen and mouse pointer. He came and got me. The pointer would move but nothing else responded. So I did a power shut down. On reboot, the machine took around 40 seconds from seeing the dell logo to the sign on screen. This seemed very long. So I rebooted the other machine to see how long it takes, and it was only 3 seconds from the dell logo to the sign on screen. I do not know if the long boot time has been going on or just started with this issue.I ran sfc /scannow and it said no issues.I remember in September 2015 ( a year ago) I had an issue with this machine where on power on, all I would get is the spinning dots at the Dell logo and it would not boot into windows. I even let it sit there for 24 hours and just spinning dots. I even tried new install of windows where the machine would let me install new windows, but after updates, the same thing happened with the spinning dots.After a tons of troubleshooting, a dell tech recommended pulling the cmos battery. I did that and from then on it booted fine.So since the long boot time did not seem right, I pulled the cmos battery again. waited 30 seconds, put it back in and booted into bios, change the clock (not sure if I had t...

Its a packard bell laptop, and the system started to freeze for no reason. No viruses. Now, I can usually only move the mouse pointer-if it lets me start windows at all (xp). As of tonight, the system wouldnt let me even pass the startup screen, it kept asking for a non existent system password to continue! The system bios clock seems to reset itself too, so I believe the whole problem to be related to the cmos battery.

My main question is, how much should I roughly be expected to pay for a cmos battery and installation from a general pc repair store? The laptop is out of warranty, so I dont really want to be spending 30+ just for Packard to find and install one either. The reason I need someone else to do it is because this particular packard system has the most awkward setup, and therefore access to the battery is next to impossible..

as you can see from my (slightly blurry) photo-

there are only 3 panels on the back of the machine that you can remove- 1 hard drive, 2 ram, and 3 wifi card (I think!).. the cmos battery (the circle!) is to the right of one of the panels, under the casing. I have tried removing the entire casing, all screws and connections, and even from the front, trying to get to it by removing the keyboard, but it proved impossible to me, so Id rather get someone else to do it. No doubt the difficulty is on purpose so that you would always send it to packard for repair, and for a high price, bu... Read more

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!

Hey everyone! Hopefully someone can help me. I've been having this problem for maybe 2 months now where my laptop would shutdown randomly and give me a real time clock error. I googled around and found that replacing the cmos battery would fix the problem. I tried it out but still i am getting this problem. Any ideas?

A:Dell Inspiron 17 7737 - Still getting real time clock error after replacing cmos battery

If the system is in warranty, call Dell for replacement of the reserve battery.
If it's out of warranty, try replacing the battery yourself (it's a CR-2032 button cell).  Manual is linked below.  If that doesn't solve the problem, the clock chip has failed and the mainboard will need to be replaced.

Hello everyone,
I have been having a problem with my laptop recently. A few weeks ago my laptop turned off, and wouldn't turn back on. I did some googling, and found suggestions to remove the memory, SSD, and CMOS battery, wait, then put them  back in and try again. When I did that, it didn't work the first few power button presses, but then it turned on. It has been consistent like that. I have the battery out, and on AC only, when I remove AC and CMOS battery, then plug the AC back in, the laptop will boot after hitting the power button a few times.

Any suggestions?

A:Cmos Bad Check Sum Error On First Boot

Your CMOS battery is dead That's all.

Pop it out and go down to a hardware store or a radio shack and get a replacement. It's about the size of a quarter and is usually located near the bottom right of the motherboard.

Been working fine until a few days ago. When I turn it on it says 163 - Time and Date not set - There is no option in bios to set date Non-System disk or disk error replace and strike any key when ready - Bios cannot detect hard drive So the question is if the RTC Battery is weak or dead can it cause above issues Thanks Chris

A:Question about RTC Battery (CMOS Battery) and System Errors

CWILLIAM83 Hello;Allow me to welcome you to the HP forums!The answer is actually -- yes and no. A weak or dead CMOS battery will prevent the BIOS settings from being saved when you power off the PC. If the default settings work OK with your hardware, then the only thing you would notice is that the clock resets. But, if you customized your settings to see the hard drive, then the default settings might not see it. After you replace the battery, you would have to go through configuring the settings-- again.Good Luck

I have just replaced my CMOS/BIOS battery today, as , I have faced some critical problem regarding regular BIOS date/time reset after system shutdown. But I want to know how do i recognize, that my new batter is totally ok or functional.

Battery Meter gadget shows that "battery Not charging"
Is it a gadget problem?

Is there any method available so that I can track that my new installed CMOS battery in PC is working fine?

Please help me.

A:Battery Meter shows CMOS battery not charging

The battery you have replaced is solely there to maintain the clock and other BIOS settings (if you have changed them from their defaults). It will not prevent you from booting your system if it is dead/missing; all it means is that you will have to enter the BIOS each time and make the correct settings and time. This battery is not rechargeable.

Do you still have to enter the correct time, or is the BIOS maintaining this now you've changed the battery?

I have an older PC which I gave to my mum. It originally ran Vista, but I bought and installed Windows 7 Ultimate around 6 weeks ago after it had been inactive for 3/4 months. It was running great, but a couple of weeks ago it just started hanging for no real reason. Also, at startup it would say that the computer had not been shut down properly, even if it had. This was only when it was switched off at the wall, not after a restart or when the PC was left plugged in and switched on. She only uses the PC to look at You Tube and some webcams from her grandkids, and that's it, she's not very computer literate.

Initially, I left Windows repair to run overnight, but when I looked at it the following morning it was still in the repair screen, so I assume it had hung. I spoke to a local repair shop and they suggested I test the RAM, test the hard drive, and replace the CMOS battery. The RAM and hard drive checks went without any errors and after I replaced the battery the hanging stopped. I played with the computer all evening and shut it down as normal and switched it off at the wall. Next day I thought I would start it up just to check it and I was faced with a "cmos checksum error - defaults loaded" message. I thought that was strange, but maybe the battery was dead, so I swapped it over with one from my perfectly working desktop to try it out, and my desktop worked fine, but after shutting down my mum's one it had the same problem when power was p...

A:"cmos checksum error - defaults loaded" after battery replaced

I must add that the PC is the same as when I bought it new from the shop, except for adding a Creative Labs sound card (approx 2012) and installing Windows 7 (around 6 weeks ago). All Windows updates are downloaded and installed.

I just got a J79X4 battery for an e6230, and while it appears to be genuine, it is a few years old, and completely flat.
I'm not too bothered if it won't have full capacity or less than the ideal cycle life, but what does concern me somewhat was that the pack is around 7.5V, which for a nominal 11.1V (3S) battery is ~2.5V cell. That does seem disturbingly low for lithium chemistry, though the BIOS reports it as 'healthy'.
A short test with Batterymon showed it charging at a low rate (~200mW), and if it is genuine, I'd assume the protection in it wouldn't let it charge if the cells were dangerously discharged.
Would anyone know specifics of when genuine protection does prevent charging?

A:Is old/flat latitude battery safe to charge?

davew_uk110,It should be fine to charge the battery if the health of the battery is good. I cannot sat how long it will take to charge.

This is a first...

A friend was visiting for three days and a few things seemed to change. He shut off my monitor when not using the PC. It didn't come back on when I hit the power, so I hit the menu button and tried to get the thing up & running. I didn't get into the monitor's menu.

That's the only thing that was done differently. Now XP asks for the CMOS setting every time I boot up. It asks for standard (F1) or advanced (F2). When I do the standard setting, my computer starts back to the year 2002 at 12pm.

How can I get things back to normal, when I turn the PC on and it boots up in XP like always?


A:CMOS setting: XP won't boot w/o going through CMOS

If the date changes, chances are that the CMOS battery needs to be replaced. Just a co-incidence on timing and your friend, I'd say.

I have in my possession a hard drive with Windows XP Pro 64-bit. The OS resides on an NTFS file system partition of half of a 500 Gig hard drive. It is part of a custom built system and has had only been formatted once. This installation has been active for about six months. It did encounter a virus which infected the System Restore files and thus were cleared via safe mode. Since that time Safe Mode has been inaccessible. Consistently stopping at the acpitabl.dat file.

However, when booting Windows normally, the system boots with proper speed and with no apparent issues and continues to work for days on end.
It is only when booting into Safe Mode that any issues become apparent.

I am curious as to any solutions this fine community may have to offer. I received great information from the Hardware group and hope for the same here.

System hardware includes:
AMD Phenom Quad AM2+ Black Edition
Gigabyte MA790GP-UD4H
G.Skill Memory
Corsair 1000W PSU
Windows XP Pro x64

Hey,I really need some help with the following issue: Details:HW: Y520 with 16GB RAM, GTX 1060, SSD (GPT) + HDD (MBR)SW: Win10 pro - including latest updates. On GPT based SSD and in UEFI mode.BIOS: latest one is loaded Problem:In short; The FIRST boot each day is unsuccessful, but the SECOND right after the failed attempt is always successful. More details:This also happens, if I switch the notebook on after not using it for a few hours, like 3h<So during the first attempt the notebook is just freezing and and I have to press and hold power button. The last thing I can see is the lenovo logo and the stopped spinning circle animation. Notebook doesnt react to ctrl+alt+del.The strange thing is that right after these 1st attempts the 2nd boot attempts are always successful, windows10 loads in and no problem after that. What I already checked:-Windows event viewer: There are no records from the failed boot, I guess because windows is not even loaded.-Drivers: All drivers are installed-BIOS: I didnt see any related setting. The OS was installed in UEFI mode and bios is set this way (UEFI)-I run all the quick and deep hw diagnostics test on lenovo support page - No issues.-Win10 reinstall: Even after a clean install the freezes are still happening. Installed win10 twice but no change, still freezing.What causes the freezes!?If needed I can make a video as well.Thanks in advance!

I have an odd problem, but will start slow with the weird behavior rather than giving a lot of detail at first. If more is need, feel free to request. Hopefully the issue is apparent from the main symptom.

Sequence of events

1.Dual boot (win7 / win 8.1) - previously working - both on SSDs. Using Easy BCD on both OSs
2.Recently change mobo battery (worked fine immediately after change other than having to re enter bios boot order)
3.Shut down computer to sort cables behind. Switch off Power supply before pulling cord
4.Started having boot issues again. The following screen appears (sometimes the black one shown in attachment, sometimes blue with white text)
5.ctrl-alt-del on screen leads to successful boot (choice of OS comes up)


A:Dual Boot - need soft restart for successful boot

Hi and welcome to TSG.

Try swapping the SSD's in the Bios boot order.

Is it possible to leave a CMOS battery out of a computer for 24 hours without hurting anything?

I recently had a major computer crash following a lightning storm and a lengthy power failure. I feared the worst and called out a tech. It turned out that the CMOS battery was dead and when the power had failed, the CMOS settings were lost.

The tech said that under normal circumstances, as long as the computer was connect to the power supply, the settings were retained but when the power failed, the settings went.

So if I just use system shut down on the computer at night, there is obviously power still getting to the computer. However I assume if if I actually turn off the computer on/off switch then there will be no power getting through and the CMOS battery takes over.

If I do that every time I turn off the compueter I assume that the CMOS battery will not last as long.

Am I correct?

Do I have to do anything after changing cmos battery? 

A:Cmos battery

Assuming that the CMOS battery was already changed, it would be wise to enter the BIOS, check the time & date and then set the BIOS to defaults, save and exit.
