Not booting or power saving issues on G500s

Hi,Lately my G500s is not waking from sleep correctly, or booting. When I open the laptop it gets stuck on the black screen with only a white lenovo logo.  there is no little round swirling icon to show the laptop is booting.  Odd things have been happening when I go into sleep mode, but at this time I am not sure.  So far, if I uplug the laptop and remove the battery, then hold the power putton to discharge what ever... then put it all back together again it seems to work.   Running windows 8.1.  This is becomming a real bitch.   has anyone had any powersaver software issues and how did you fix it. There have also been a few occassions where the touch screen stopped working and I had to reboot. Kevin   

See this thread: https://bbs.archlinux.org/viewtopic.php?id=150743
I've personally rolled back to 3.5.6 and have no issues. Alternatively, you can try some of the fixes noted in here (installing some of these patched kernels). If I recall correctly, there are people in this thread with the same machine as you.

  • Adobe Reader 2.0 for PocketPC power-saving issue

    Hello,
    I have a Fujitsu-Siemens LOOX720 device and noticed that device battery discharges relatively quickly when I read PDF documents with Adobe Reader (Windows Mobile 2003SE).
    The trouble is that device runs at turbo processor speed all the time the Adobe Reader document is viewed (even when you switch to other applications and put Adobe Reader instance to background).
    I set the processor speed settings of my device to Automatic Mode and the rest of applications work as expected - they do not consume much CPU power when they are idle and the CPU is automatically switched to power saving mode. This does not happen when Adobe Reader is viewing the document and the only solution is to set the CPU settings to Power Saving mode manually. This is very inconvenient because rendering of PDF documents is too slow in power saving mode.
    I hope the description is clear and it will help to fix this problem in future versions of Adobe Reader.
    Thank you!

    >>> battery drain happens only when the device is powered on and there is running instance of Adobe Reader with opened document. <<
    Actually, my experience is continued battery drain when powered OFF and there is running instance of Adobe Reader with opened document.
    One possibility is that when the midnight calendar update occurs, an open instance of reader may keep the unit powered on.
    On windows mobile devices, the power button is a "suspend" button and applications remain open, and while normally inactive, some programs continue to run and make power demands on the ppc.
    >> report to adobe <<
    It's been pretty obvious over the years that Adobe does not care about nor will invest any resources in the ppc reader to address any user issues.

  • HP G62 Will Not Boot With Power Cord Plugged In

    I have an HP G62 laptop that is about four years old. I've had a couple of problems with it before that were resolved relatively satisfactorily, however five or six months ago I started having a new issue. The laptop will not boot with the charging cord plugged in, whether there is a battery in it or not. Nor will it return from sleep mode (screen black, status light on the power button flashing) with the charging cord plugged in, whether there is a battery in it or not. It simply shuts down and I end up with an error screen the next time I boot up. I have tried other charging cords and it has been the same, however the cord will still charge the battery. This means I have to charge the battery, unplug the cord, boot up the computer. This annoyance is worsened by the fact that the battery  is old and unable to  hold charge for very long at all and I fear one day even the battery won't be enough to boot the computer.Can I fix the power cord issue? Should I buy a new battery? Or let my computer give up the ghost and scrounge for a new one? Any help would be greatly appreciated.

    the charger input could possibly need replaced and/or the charger

  • 3400c will not boot/ green power light remains on

    Strange thing happened. We lost power while I was away and when I came back my 3400c was on (the green power light was lit) but it will not boot, shut down or power up. Will not respond to the power button or force quit keys. I tried removing the cd drive, the battery and unplugging but when I reconnect the power all that I get is the green light. No internal noise, won't boot. Also, I tried pressing the reset "button" in the back and the green light will flash but nothing else happens. It hasn't been my main computer for awhile and I no longer have it connected to the internet but it is nice for the kids to run their cd games on it. Anyone have any idea on how I can go about troubleshooting this laptop.

    I've done a ton of tinkering with my 3400c, and currently am having fun installing Linux on it. Through my adventures with this thing, I've occasionally seen the stationary green light.
    I'd recommend removing what's in the media bay, and any PCMCIA cards, unplugging all components and removing the battery.
    Disconnect the unit from power and press the PMU reset button on the back, and hold it for several seconds.
    Let the unit sit for about 10 minutes, just to be on the thorough side. Then reconnect the power cable (no battery/media bay necessary). What SHOULD happen is an immediate boot chime.
    If the issue persists, you might try booting into open firmware:
    Hold down Option + Apple + O + F, and press the power key on upper right of keyboard while holding these keys. Hold them down until you (hopefully) see a grayish-white screen.
    If so, type these lines, return after each one:
    init-nvram
    set-defaults
    reset-all
    If all goes well, should reboot normally. If not, you may have a hardware issue on your hands. I'd try disassembling it and removing debris, looking for loose components or any point of failure, but if not you may require a new logic board. Luckily, either a 3400c or Kanga G3 board will work with these models if that's the case. (Only caviat is that the ram that originally came with some 3400c models will not work on the Kanga logic boards).

  • Tecra M2 - Will not boot up, power light is on

    Hi, I wonder if someone out there could help me with a problem?
    I was using my M2 on Friday when my friend accidentally knocked a very small amount of soft drink onto the front of my M2, I immediately put it upright and got a hairdryer on it.
    After leaving it an hour I tried using it and everything was working as before which was a great relief, however a day later I was using the M2 to check my e-mail when all of a sudden in went off.
    The power light is on was still on and so was the light that indicates I have a CD drive slotted in, I tried many times and it would not boot up, so I left again for a day and yesteday morning it looked like it was booting up only to freeze on the Windows screen, it then did it again and it hasn't booted up since.
    Could anyone please give me some advice on what I could possibly do to fix this problem?
    Regards,
    Russ

    Hello Russ
    Please be realistic. What you can do in this situation? Not much! You can try to start the unit. See if you can enter the BIOS and if yes how long the unit stays ON. If the unit works for a longer period you can try to boot up from CD (for example with recovery media).
    You can try to connect HDD as external one to other notebook and try to save all your important data and install OS again. More than that is not possible. If there is some electronic malfunction it is not easy to fix it on your own and helps just technical investigation to see which hardware component is damaged.

  • KT6V + sempron 2800 does not boot when BIOS saved

    Hi,
    I have just bought a new sempron 2800 to be use on a KT6V LSR. I plugget in my KT6V but was not recognised well (but all was working ok with windows). To be recognised, I have flashed with the last bios of MSI my motherboard... and now I have the following problem:
    - I clear CMOS, then boot. It comes ok (processor detected and set a 1200Mhz)
    - Then CMOS has a bad checksum: I enter setup, then load default, save.
    - I reboot: the computer does not boot up.
    If I re-clear CMOS I can re-enter setup and modify frequencies or other options. But when I save my modifications, then the computer does not reboot anymore (I have to re-clear cmos again)...
    I tried to apply the configuation I found in this thread:
    http://forums.amd.com/lofiversion/index.php/t69536.html
    It says that SDRAM must be at 333, FSB at 166 and multiplicator at 12. When applying this settings, it does not boot (the leds indicate that the chipset initialisation (the first step) does not pass).
    If I just load biios default, the leds indicates that it fails when checking the memory (second step of boot). I suspect that it's a problem of memory (but my memory was working well before !): it's 2x512 of DDR 400.
    Any suggestion is appreciated :D . I spent several hours trying to configure the bios but it does not boot..
    (I'll also try to find help on AMD forums...)
    (Some extra info: my PSU is 26A for 12V, so it seems that it's not due to the PSU (as I read in the FAQ of this forum).
    Thanks,
    Ptitmain.

  • X99S GAMING 9 AC Not booting - Debug 94 code - Issue with GTX 980 SLI in WoW

    Hello, I bought the X99S GAMING 9 AC motherboard but have ran into some issues.
    The computer won't boot when I put my second MSI GTX 980 Gaming 4 GB card in the last PCEI 3.0 port (PCIE port 5) and I get the debug LED message 94 on the motherboard. I have a SLI setup.
    The first card I have in the second PCIE 3.0 port due to the Noctua U14S CPU fan takes up space for the first slot. So I have been running my grafic cards in PCIE slot 2 and 4 with some issues.
    First the card in slot 2 gets really warm over 86 celsius. And second: SLI runs really poorly in World of Warcraft. I get a lot higher performance with just one card activated. I am not sure if it's cause I am not running my cards in the recommended PCIE 3.0 ports or because WoW has some issues with SLI, but I heard other people have no issues at all with WoW in SLI.
    I got the same issue with 3Dmark firestrike, the cards perform really poor in SLI. I get higher score with SLI turned off..
    Though SLI seems to run pretty well in 3dmark 11 and Diablo 3 Reaper of Souls.
    But the main issue right now, is that the computer won't boot with the grafic cards in PCIE port 2 and 5. The solution to run them next to each other is not good, cause it gets really hot and I get bad performance in WoW and Firestrike.
    Picture of my setup before I switched places with the grafic cards as you can see, it is really tight:
    Any upcoming bios updates (got v1.3) that will solve this issue on the horization? Hopefully this get sorted out really soon..
    My whole computer setup:
    Intel i7 5820K | MSI X99S Gaming 9 AC (bios 1.3) | SLI MSI GTX 980 Gaming 4GB | Samsung 850 Pro 512 GB | WD Red 4TB | G.Skill Ripjaws DDR4 3000MHz 4x4GB | EVGA SuperNOVA P2 1000W | Noctua NH-U14S PnP | Fractal Design Define XL R2 | 5 Noctua NF-A14 PWM 140mm fans | Windows 7 Pro 64 bit

    You must use the recommended PCIE slots as the manual says for your CPU type, PCIE #1 and PCIE #4 if I remember, just open the manual :P for optimal 2Way SLI, also your 5820k will limit to 28 pcie lanes only if you plan to add more vgas...the other problem is your giant CPU air cooler blocking PCIE#1, do a favor to yourself, buy a watercooler for your 5820k and your problems are gone, add some overclock in your system, low noise and better temps.
    Here I use 3x980 in SLI with X99S Gaming 9 AC, going soon to WC the VGAs with EK blocks.....3way is far more temperature critical than 2way spaced one.
    Cheers

  • T430 not booting - flashing power button

    A friend of mine asked me to look at his T430 because it wasn't booting.  Basically as soon as you plug the AC adapter in the CPU fan turns on (sounds like full speed) and the power button pulses / flashes (once every 2 seconds fading in and out).   I have stripped everything out (down to the mainboard but still doing the same thing.  Even with the processor and memory out still does the same thing.
    Without AC and the battery in pressing the power button yields the same result.
    Does anyone have any suggestions? Heard of this? Know the solution? Or even know what this type of error signifies?
    Any help would be greatly appreciated, I need to get it fixed for him ASAP.

    Hi, welcome to the forum!
    I hope that this classic trick will help you with your troubles:
    Remove battery and power cable.
    Press the power button 10 times in a row, each time just for a fraction of a second. Then press it once again and hold it for 30-40 seconds and release. Try to start it again, post back here with results.

  • Powerbook Fell, was working fine subsequently. does not boot on power up

    My PowerBook G4 fell down (about 2 feet onto carpet) and landed on its
    battery side. The machine was working fine after that (did some web
    browsing, etc), however there was a dent near the battery. So I
    powered it off to remove the battery and straighten out the dent. When
    I power back up, the machine does not go past the apple screen. I put in the OS CD but nothing happened. I tried resetting the PRAM and the PMU, no difference.
    It does not let me go to either the single-user or the verbose mode. I tried to boot using the shift key and it showed the apple sign and the rotating counter thingy for a long time and nothing happened. Now I cannot even plug my install disc into the DVD player. HELP!!!

    Boot in save mode -You say that works and insert your 10.4 disc into the DVD slot if it accepts it.
    Now boot to the disc.
    In the menu bar i think its options choose disc utility and repair the drive .
    From what you have said i suspect you mechanical damage has taken place either to your HD or the DVD drive.
    Both can be fixed and if you want a challenge (Like removing about 50 screws) you can do it yourself
    It will save you about $150-$180 in labour alone.

  • PC will not boot from power up

     Since I purchased and fitted a new MSI K7T266 Pro2-U Mobo , the PC won't boot up from power on past the Win98 startup graphic. When I hit the reset button, it boots in safe mode, and will reboot OK after that, except that the memory show is only 256 mb , when I have a 512 mb Dimm . Also the PC is very unstable. After ready thru your other posting, I purchased a new 300 Watt PSU, but this has made no differance. I played around with all possible wiring combinations from the PSU to my devices, but no joy. Any ideas ?

  • Mac Pro will not boot. Power led just flashes

    When I start up, the HD spins but then the power led starts flashing at a constant rate. It also never gets to the gong. I tried everything on the support pages.

    Power On Self-Test Beep Definition - Part 2.
    It would be helpful to be more specific about the flashes such as the sequence, timing, etc. So, you will need to examine the above and its links to see if you find something descriptive of what you have.

  • No power saving

    Hi!
    I've just installed Arch 64bit on my Lenovo g560 notebook and I'm experiencing some power saving issues. On windows my notebook can run about 2,5-3 hours with wifi on but under linux it runs less than hour! I installed and configured laptop-mode-tools and cpufreq-utils, daemons are running but it looks like power saving is not working at all.Any ideas?

  • L505D-GS6000 Will not boot

    My Satellite L505D-GS6000 will not boot.
    Power indicators on front turn on (including battery light), I hear the DVD drive spin up (empty), but the screen remains dark (no BIOS info), and the HD or wireless lights never light (not even flicker).
    I have done the following with no change:
    removed the battery and tried with just A/C
    removed power cord and tried with just battery
    removed and reseated HD
    removed and reseated RAM
    Tried with one RAM card (tried both, one at a time, in each slot)
    left overnight with power off
    Also, I do hear the fan run when I turn it on.
    Your help is appreciated, as I am unemployed, and cannot afford to have it serviced (and my resume, email, etc. is on the HD).

    There's not much else you can do. If you have an external monitor, you could try connecting it to see if it'll work. It's possible that the LCD went out in the notebook. Of course, this won't fix it, but it might let you still use the computer.

  • M93p BIOS issue: PowerOff not correct if Enhanced Power Saving Mode Disabled and Wake on Lan Enabled

    Hi Levnovo support team, Recently I bought a M93p tiny(10AAA05MTW)(BIOS revision FBKT56A)and installed with Ubuntu 13.10 myself.Then tried to enable wake on lan for my tiny. The followings are my test result. 1. Enhanced Power Saving Mode Enabled, no mateter what is Wake On Lan setting     PowerOff system is OK. 2. Enhanced Power Saving Mode Disable and Wake On Lan Disabled    PowerOff system is OK. 3. Enhanced Power Saving Mode Disabled and Wake On Lan Primary or Automatic   PowerOff system is NG.   When I tried to power off system, it always can poweroff(LEDs on front all off) then POWER ON again in 2 or 3 seconds.   I cannot accept this test result ,system should poweroff not reboot again.   It's really hard to understand why enabling Wake on Lan will affect power off function. I tried the same procedures with my another M92p(3212A16)(BIOS revision 9SKT70AUS), and it works well.   

    Did you ever get a fix for this?Having the same issue on 3 of 6 machines that just arrived. 

  • Power Saving turn monitor off not working in XP Pro

    Hi I just got a new 24" imac (the previous generation, white model)
    In windows xp the screen saver works, but the power saving feature to save the monitor and turn it off does not work. Many other people are having this same problem but apple has not fixed it yet.

    please help

    I think I resolved this! I had the same issues you have been having for a few months. I am actually running Vista. Here is what I did...
    1. While booted to Windows I uninstalled boot camp
    2. Re-installed boot camp from Leopard DVD
    3. Installed boot camp update 2.1 (downloaded from Apple support, i know this is for XP only, but I updated anyway.)
    4. Downloaded the realtek drivers (high definition audio codecs) from http://www.realtek.com.tw/downloads/
    5. DO NOT use the Realtek installer to install the drivers...instead extract the contents to a folder.
    6. Go to the device manager, locate the High Definition Audio device and updated the drivers from here (point to the folder where you extracted the drivers).
    I now have sound out of the rear jack!! Hope this help someone
