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.

Hi, In Lenovo`s website it says that Sierra Wireless EM7345 FRU 04X6014 has GPS as well. So, I installed it on my x1 Carbon gen2, its network is working perfectly but when I tired its GPS it isn`t. When I open Maps of Microsoft or installed other apps it didn`t work either. So, where could be the problem.. is it the app/program or it`s the modem I am using Windows 10 Pro Thanks,Kushtrim

WARNING!!! The instructions in this post are applicable only to EM7345 installed in Lenovo laptops!! For example, models T440, X240, X1 Carbon 2nd and 3rd gen, X250. For tablets or other devices don?t use the firmware given in this post, you can brick your EM7345! Unfortunately, the default factory EM7345 firmware version  (1.1) has some bugs. For example, after connecting to a LTE network and then disconnecting manually, the network status of the connection was changing for me to ?No service? until device restart. Also, the device often disappears from Device Manager and reappears there with the name ?1 CDC? and does not work until you disable and then enable it again in Device Manager. All those issues are caused by some bugs in EM7345 firmware.But there is a newer version of firmware, namely 1.2, where the above bugs are fixed. But by default, you cannot flash it, because firmware updating is supposed to work unattended. And this is not nice of Intel and Lenovo. The users must be able to do firmware updating when they need or want it! Bad, bad Lenovo, very bad! Here?s the instructions of how to flash your EM7345 to the latest version:Make sure you?re using Windows 8 or 8.1Go to the control panel and uninstall Sierra Wireless EM734x 4G LTE Software from Program and Features.Reboot your laptop.Download and install the latest EM7345 driver package from the Lenovo website. http://support.lenovo.com/us/en/products/laptops-and-netbooks/thinkpad-t-series-l...

Answer:ThinkPad W540 Work with Sierra EM7345?

Since it is listed in the official parts-list for the W540: Yes. However, you will need a Lenovo branded card (04X6014, which is the Sierra Wireless EM7345 LTE/HSPA+ 42Mbps M.2 Card).

How to flash the firmware of the sierra wireless em7345 on windows 10 ?  Its not possible through the steps i could find which was only for widnows 8. 

Answer:Sierra Wireless EM7345 windows 10

HiOnce the modem drivers are installed, including Intel flash tool, and the sim card inserted, during laptop cold start the flash service checks out whether newer firmware is available according to current modem fw and the sim card data (more clearly, cellular operator MCC/MNC values), and performs the flashing process if it's needed, in auto mode. You should see appropriate notification from the flash service in the system tray.

Hi Support, I would like to change a setting, so that the Sierra Wireless Adapter only connects to 4G networks. In Windows 10, I cannot see anywhere where I can easily set this. I would expect there to be mobile management software where these settings could be changed. I never want to connects to GPRS, and would like my Sierra Wireless mobile card to only connect to 4G or not connect at all. This would prevent the card dropping down to GPRS when the signal is temporarily weak and force it it to try for a 4G connection. I have had similar functionality on prior USB mobile data cards I.e. Vodafone, and hence the expectation that there would be similar settings on the Sierra Wireless. Thank you, George

If I have understand correctly EM7345 is made specifically for Lenovo based on their requirements and specifications. Lenovo is also responsible for this firmware....on Carbon X1 etc...   I found an interesting AT command for Sierra Wireless EM7345. The command is ?AT+XCIQ?. There?s the following text string in EM7345 firmware file (it is present in any version so far): +XCIQ CIQ: Carrier IQ enable/disable.Let?s try to get ?help? about this command:  AT+XCIQ=? +XCIQ: (0-1) OK1234AT+XCIQ=?+XCIQ: (0-1) OKSo, we can suppose that 0 disables this Carrier IQ feature, and 1 enables it.Let?s read the current setting of this feature: AT+XCIQ? +XCIQ: 1 OK1234AT+XCIQ?+XCIQ: 1 OKLooks like it?s on by default. Let?s try to switch it off?NOTE: If you?re running firmware earlier than 1522.02, don?t enter the following command!If we try to enter: AT+XCIQ=01AT+XCIQ=0i.e try to disable Carrier IQ, EM7345 will have a fatal crash and reboot into boot flashing mode and it will be stuck there for good.So, Carrier IQ is always on and if you try to turn it off using the above AT command, that will kill the device!With firmware version 1522.02, AT+XCIQ=0 returns OK and there?s no fatal crash like in previous firmware versions. Also AT+XCIQ now accepts 3 possible values with 1522.02 firmware: AT+XCIQ=? +XCIQ: (0-2) OK1234AT+XCIQ=?+XCIQ: (0-2) OKSo, 0 must be disable, 1 enable, and what is 2?

Answer:X1 Carbon - Driver Sierra Wireless EM7345 ?

Hi, jkuengWhat's the OS installed on your laptop? For win8/8.1 there are no needs for drivers if the card is in MBIM mode. It must work natively in OS. Let's check it. Look at the Device Manager, open Network Adapters item. You should see something with AiarCard. Open Properties, Details tab, pull down Options list, find out an item Compatible ID. Looks like USB\Class_xx&SubClass_xx&Prot_xx). Copy the values and past here. Will look.
 
Also, could you, please, post here USB IDs of this card? Find it at the same list under Hardware ID item (looks like VID_xxxx&PID_xxxx).

I am using the EM7345 in my X1 carbon 2014 on a daily basis. It works flawlessly with my local 4G SIM. (No need for APN settings)I went to Spain for a week and tried 2 different providers: Labara and Hits mobile.They are both guesting in Vodaphone's network.In the network connection dialog they both indicate Vodaphone ES with an additional roaming indicator.When trying to connect they both ask for an APN string: gprsmov.lebaramobile.espc.hitsmobile.es After clicking connect it takes like no time till it says "cannot connect," I wonder,Windows bug? (windows 8.1 update)Sierra driver bug?or maybe vodaphone trouble? btw, I also tried a "native" vodaphone ES sim (no need for APN settings)Worked perfectectly ! Any suggestions?

HelloI have a W541 running Windows 7 (64bit). I've found 'Sierra Wireless GNSS Sensor EM7345 4G LTE' appearing with exclamation mark icon in the device manager. Lenovo solution center also shows it as disabled device. I have downloaded and installed latest driver (2.17.10870.4454). After installation the device seems fine in device manager but as soon as I restart the notebook the device appears again disabled in the device manager. I?ve just found in the README file the W541 is not listed as supported model by Windows 7. According to this file W541 is supported by W8 or W10 but unfortunately I?m not able to install any other OS on the laptop.Can I expect to have support for W541 with W7 in a future software release? ThanksZoltan

I'm having the same problem with my Sierra Wireless 7345 on a W550s running Windows 10. It came with the laptop, so I'm sure it's supposed to be compatibile. I think it's a driver compatibility problem. Unfortunately, I've just chalked it up to the "Windows/Lenovo" tax - some things work, others just don't. I've gotten no reponse from Lenovo.

Hi , I have updated to the 1607 Anniversary Update in August and noticed that my WWAN Sierra Wireless EM7345 had problems starting up after reboot. Because of other problems with the 1607 I reverted back to 1511 and everything was alright again.A week ago I upgraded again to 1607 and again, my WWAN sometimes cannot start when booting up. The error log shows Miniport Sierra Wireless EM7345 4G LTE, {b343453c-24e6-493d-ba47-33eaec4de5e3}, had event Fatal error: The miniport has detected an internal error (details see below). So this clearly has to do something with the 1607 update or the drivers for the WWAN. I am using the latest drivers from the Lenovo website and have also tried to update drivers in device manager. But no luck. What helps to finally start the WWAN is either a reboot (the chances the WWAN is started properly are about fifty-fifty) or clicking WWAN off and on in flight mode options of Windows.  Maybe someone has an idea other than waiting for Microsoft to fix this stupid 1607? Thanks and best regards,Martin  Log Name:      SystemSource:        Microsoft-Windows-NDISDate:          10.10.2016 06:37:19Event ID:      10317Task Category: PnPLevel:         ErrorKeywords:      (16384),(16),(4),(2)User:      ...

Hello everyone, I'm a bit desperate because I already tried so much.I'm running Windows 8.1 on my Lenovo X240, BIOS version 2.3 and the WWAN functionality broke about two weeks ago and I'm quite sure that this is related to a few updates that came either with Windows or more likely with Lenovo System Update which had a BIOS update and some driver updates alongside at that time.I cannot even try to establish a connection to the Deutsche Telekom LTE network, because all I'm seeing is "Insert a SIM" in the connection bar.This is what I tried so far:Use a different, well known working SIM card.Re-Install the driver packageUninstall and re-install the driver packageuse the "repair" function of the driver package setupBIOS downgrade from 2.3 to 2.29Disable and enable the WWAN functionality in the BIOSReplace the mainboard (lenovo service technician just went away an hour ago)And I'm still having the same issue. Now it's really nailed down to be either the BIOS or the driver in win 8.1 x64. One thing makes me wonder:When I choose to update the driver in the device manager and the Sierra card details, I'm pointing Windows direclty to the directory that contains the inf files and the device manager tells me that "The best driver software for your device is already installed." and shows me a "Generic Mobile Broadband Adapter".

Answer:t450s Sierra Wireless EM7345 not working after upgrade to Windows 10

Welcome, Alexander Do you see broadband item on the cellular settings pane?The most likely cause of issue is APN setting missing in the connection profile. What is your operator name and what profile settings do you see?Win10 doesn't need modem manufacturer drivers for broadband access only, it uses built-in drivers. Also, there are default connection profile settings in the OS. If your operator is missing in that base or connection profile settings differ, you should edit profile on the cellular pane under administrative privileges.Anyway, I'm not sure em7345 modem in the Device Manager's "Network adapters" category in the win10 with OS built-in drivers installed should look like "generic mobile broadband adapter".

Answer:Sierra Wireless EM7345 4G LTE Mobile Broadband FRU: 04X6014 for my ThinkPad X250

Regarding your questions:1) I personally use it and it's really good, as I don't want to use additional USB modem or WWAN wireless router.2) Can't say, as I don't use Fedora.3) There's a dedicated port for this module. Please make sure, that you have an antenna connectors for module and adapter for a SIM card. Moreover, instead of WWAN module, you can install there a m.2 2242 SSD disk.4) Both can be enabled and connected, but application will use one at time.5) I have an extended battery, so it's hard to tell. I guess it have a simmilar power usage as WLAN module (basing on Windows power utilization). Can't say about Fedora.6) It you don't want to have a problem with whitelist (it prevent system from booting, when unauthorized module is installed), then I look for module on eBay. Make sure, that photos explictly show FRU PN: 04X6014 on module's label. Models without it will not work.

The compute recognises the card with no issues. Unfortunately, however, when a simcard is inserted it does not register the simcard whatsoever - 'Insert sim' is still present.In my searches on this forum it seems this problem is Windows 10 specific - the system does recognise the wireless card but does not recognise the simcard reader. Anecdotally, it seems to work for others when using Windows 7 (although that wouldn't be a fantastic solution in my situation.)Is there any solution for this?Thank you in advance for your time and any responses!Jack

Answer:Lenovo Thinkpad T450s, Sierra EM7345 and Windows 1...

Hello, jraynerwin10 doesn't need wwan card's manufacturer drivers for the normal mobile connection, it has a native support that. Additional drivers are needed for the legacy location features via NMEA port, for the custom wwan card virtual devices configuration (like NDIS port etc).So, the 1st thought modem firmware is outdated. Check it out:open command prompt window (cmd) and type in the following stringnetsh mbn sh cap int=*Copy and past an output here (remove Device ID for your privacy).Another version is connection settings, APN mainly. Do you see a cellular network item in the win10 network settings?Anyway, I hope mobile device em7345 is present in the Device Manager w/out errors.

Hi there, I have a W541 with Sierra EM7345.I had and now have a lot of problems with the WWAN-Card, and more like you can read here: https://forums.lenovo.com/t5/ThinkPad-P-and-W-Series-Mobile/W540-Freeze-on-boot-screen-when-connecte... And now i cannot reinstall the driver because it's not supported for Windows 7 x64 any more:Sierra Wireless EM7345 Software for Windows 10 (32-bit, 64-bit), 8.1 (32-bit, 64-bit) - ThinkPad Now I have supported hardware with no driver available?!

Answer:ThinkPad W541 no driver Win7x64 support for Sierra EM7345 any more?

Hi aschulte,
 
If you have a W541 then you need the driver for the EM7355 card; that's what should be in the system unless the parts list and psref are mistaken.

I have a T440 with Sierra LTE. It works just fine for connecting to mobile networks.But here in New Zealand, one of our providers also provides free wifi hotspots to customers on certain plans. In order to use this though, I have to enter a password that is sent to me by SMS.Is there any way that I can view SMS messages sent to the SIM card that is inside my laptop?At the moment, I have to remove the SIM from my ThinkPad (with all the hassle that involves), stick it into my phone, get the password, then transfer the SIM card back into my ThinkPad (and often as not, there is no power socket nearby, so I can't restart because I had to disable the internal battery when removing/replacing the SIM card).So, if someone can point to a way that I can simply view those SMS messages on my ThinkPad, I will be enernally grateful.

Answer:A way to send/receive SMS messages on ThinkPad T440 with Sierra EM7345

Use Lenovo Access Connections if OS on your laptop is win7, or Sierra Watcher connection manager for both OS, win7/8.

I upgraded my Helix Gen 2 to Windows 10 with few problems except for the Sierra WWAN interface to Windows 10 settings. The cellular button on the wireless menu is greyed out and the cellular option page in settings shows no devices. The adapter setting shows the adapter, and on the Settings, Network & Internet , Airplane mode page show both Mobile broadband and Wi-Fi buttons. WWAN can be enabled by truning off Wi-Fi and turning on Mobile broadband on Airplane Mode settings page. With these settings, I can connect to WWAN Verizon and get to internet but:1. Settings, Network & Internet , Cellular shows no connections2. Wireless pop up menu shows Cellular and Mobile Hotspot greyed out. So, in summary, I can connect to WWAN, but only via Settings, Network & Internet , Airplane mode page using proceedure above. By the way, my upgrade to Win 10, switched on the rotation lock, but I was able to fix that in Win 10 settings in table mode.

HI

I HAVE AN TOSHIBA SATELLITE C55A (PSCG8E).

AFTER BATTERY FULLY CHARGED WHEN I UNPLUG THE AC ADAPTER THE COMPUTER SHUTDOWN.
I HAVE ALREADY CHANGED THE BATTERY AND NOW I HAVE THE SAME PROBLEM.

ANY UPDATE OF THE BIOS FOR THIS PROBLEM ?

Answer:Satellite C55-A doesn't work on battery power

Something like this should not happen, especially not on brand new notebook.
> HAVE ALREADY CHANGED THE BATTERY
What have you done exactly? Have you got new battery from your local dealer?

Generally speaking this should not happen and in my opinion you should ask for new machine if you can get one. Other way, I think you should contact nearest Toshiba service provider and ask for help.
In my opinion BIOS has nothing to do with it.

Hi! I have a 2y4m old Lenovo SL300 laptop Type 2738-CT0.  It works great but the battery stoped working a few days ago.  The power gauge shows 73% always, but if I unplug the cord it goes off.  The power manager says its in "Good Condition" and shows it green though.  The rest of the power manager info is: Status: No activityRemaining percentage: 73%Remaining time: -Remaining capacity: 34.38 WhFull charge capacity: 46.79 WhCurrent: -Voltage: 12.03 VWattae: -Temperature: -Cycle count: 348Mfg: SanyoMfg date: -First used date: 2009-01Serial no.: -Bar-Code no.: -FRU part number: 42T4619Device chem: Li-IonDesign capcity: 84.24 WhDesign voltage: - I tried checking for firmware updates and didn't find any, also checked the forum and the only advice I found was to check the battery with another compatible lenovo (but I have no access to any).  I guess I might have to buy a new one, but wanna be sure before I spend $180 and turn out to be a different problem.  Any advise is appreciated. Thanks!

Answer:SL300 Battery doesn't work, but Power Manager says "Good Condition"

hey ppski,it's really hard to say, but it is a possibility that the battery is at its last leg. Testing the battery on a different unit would be good.But i do recommend that you test a different battery on the unit of yours. I'm fancying a guess that maybe the unit's terminal where the battery meet could be damage.

Hi

I hope someone could help me with my problem.
My toshiba P200-1fc running Vista and updated to latest Bios will not show any light in the battery indicator led if running on battery power.
It's fine if i have it plugged into the mains.

I only updated the Bios to see if it sorted the problem .
The battery charges fine orange then blue to say fully charged but I only have the taskbar icon to see how much power is left.

Also the wife has got a U300 and the same problem has happend. I restored the laptop to a earlier time and this did not fix the problem.
I also unstalled some programs (antivius/firewall) but no joy.

It may be something simple i hope.
Thanks for any help

Answer:Satellite P200-1fc: battery led doesn't light if running on battery power

Sorry but you are completely wrong!!!

The battery LED doesn?t light if the AC adaptor was disconnected!!!

The battery LED shows only 2 signals; orange and blue (sometimes green on different models)

If the battery is not fully charged and the AC is connected the battery LED shows orange. If the battery is fully charged then the LED switches to blue (green)

Please don?t be mad at me but I think you should firstly check you user manual before posting some ?gossips? about any possible ?bugs??

Best regards and have a nice day dude ;)

Hello friends. I have a HP laptop (G62). its almost a year and half old. Everything was fine but I am having problem with power adapter for few hours.

When the laptop is off, the adapter works fine and it charges the battery. But when I turn it on, its fine for first 5-10 mints and then power adapter stops working and the laptop runs on battery. Obviously, the battery doesn't run forever. So after a while, I have to turn it off to charge the battery.

Anybody had this issue before or any suggestion?

Thanks a lot.

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

Could be a bad power adapter. It may charge, but it doesn't have enough power to keep the system running, so it switches to your battery. I'd look at getting a new power adapter.

here's my problem, as near as I can tell,

a few months ago the wireless connection on my hp laptop stopped "seeing" my wireless network. Eventually, during a scan with my panda security system a virus was found (for some reason it is no longer in the logs-but is was, I think, trojan or sasser in my outlook folders-and it was deleted). The wireless seemed to work again but then went back to being "invisible" to my wireless detector on the laptop. I went to HP downloads to see if I could just update the "driver" and ended up updating "system bios" which seemed to work also, for a while, then the system goes back to not seeing the wireless. I could sometimes do the right-click "repair" option to get it to connect but that stops working after a while. I think that there is still some residual virus lurking in the system to cause this problem so that is why I am posting here. Thanks for any help you can give

I am not exactly sure if this is where I attach the dds.txt text but will put it here just in case:

Any suggestions?

Thanks a lot!

Answer:Battery doesn't charge and Satelite A75 doesn't run on AC power

Hi

Due to the fact that yours A75 Satellite does not run with a connected AC adaptor and with the connected battery, I presume there must be a serious hardware issue.
From my personal knowledge there could be something wrong with the power supply electronic.

In my opinion you will be not able to solve this problem without the ASP help.
Therefore I would recommend to make a call to the ASP technician and to ask for the details and further handling.
If the warranty is valid, then everything should be done for free?

I hope you can clear this issue? good luck

I have an issue with a G50-45 notebook. The owner is an older acquaintance of mine who couldn't use it with the WIndows 8, which is the original OS comming with it, so in order to install a WIn 7 was needed an update of the BIOS (Downloaded from the official Lenovo support center ofcourse). After the update I finaly managed to boot Windows 7 on the notebook, but now it won't turn on, while battery is on. I tried the battery draining suggestions mentioned not once or twice in this forum, and nothing gave result.(Ref: https://forums.lenovo.com/t5/Lenovo-B-and-G-Series-Notebooks/G50-won-t-start-on-battery/td-p/2140152 )  When pressing the power OR the Novo button it is getting in a cotinous boot loop while battery is on. I tryed many varieties, but while the battery is installed - the notebook keeps restarting, but when I remove it and power on only on AC, evrything seems to be going quite well. So after I installed the new OS, I digged myself into the forum, and I ran onto the above mentioned techniques, but unfortunatelly after several tries - I give up. My question is - do you have any other ideas? Is my problem hardware, because it does not exit when I remove this particular hardware - the battery, or it is some issue because of the updated BIOS?  I hope somebody will give me the next direction how to fix what I did, please =) Thank you in advanced  BRStacy

Answer:Hp DV2000 battery doesn't work! Plz, help me!

Do you leave your battery attached to your laptop when it is plugged into the power supply? If so...DONT!!
It's always best to pull your battery when you are not mobile, since batteries have cells that contain "memory" and can only accept a certain amount of charges, or "hours of charging."

Also you want to allow your battery to FULLY drain before you charge it again. Also, allow it to charge 100% and then either remove the battery or power supply unit.

As far as the battery you have now you may need to obtain a new battery; either through your warranty or purchase of another.
Once a battery is dead, it's usually done.

Dear all,

I thought I have met this problem before before my two wireless adapters both stopped working.

PCI-E INTEL 5300
TP-LINK WN821N

My case is a little different from those I found on this forum.

1. When I upgraded my thinkpad x200 to win7 64bit, I don't have "Wireless Network Connection", but I fixed it by stopping one setting of Kaspersky and it came back, so when I first found my PCI-E wireless didn't work, I thought the same thing happened, although I didn't remember the details, I tried the Kaspersky, don't work.

2. I updated the drivers, uninstall-install, start-stop-start WLAN AutoConfig... I have done a lot that can be searched on line, never worked for me.

3. Tragedy happened, I adjusted several common options on BIOS, then after several tries I made to make 5300 work, USB wireless died Don't know how to recover it, and back to my laptop again.

Could anyone here help me out? Really appreciate it! I have spent two days on this stuff, if no one can do this, I guess the only way is to reinstall the OS, that's the least thing I want to do.

Thanks!!!!!!!!!!!!

Hi

It is not easy to say what is wrong there. Did you notice something strange with control power LEDs? It is also possible that power supply electronic make troubles. Try to talk with authorized Toshiba service and explain the situation. If you open the notebook alone without instruction it can be just worse.

Graphic card can not be updated like on desktops. I don?t know how it is on this notebook model but graphic card is fixed on mainboard and can not be exchanged.

Hi,

I've noticed a little problem in my notebook.
Infact when the laptop is in recharge the battery led is amber.
Thus far it'all ok. But when the battery achieves the 100% the led turn off, instead of turn into the blu color, as usual.

Does anyone know about this problem?

Thanks.

Answer:Battery Led doesn't work Satellite A100-926

Hi

Hmm? did you check the BIOS if there are any settings regarding the battery LED?
Access the BIOS and check this!

At the other hand if could be something wrong with the LED?s and therefore it would be advisable to contact the ASP in your country for a check!

It?s your decision and you have to decide if it?s worth contacting the ASP or not.
I mean it doesn?t look as a serious issue and the notebook runs well except of the LED

The battery of my brand new satellite M70 doesn't work anymore. I didn't use the portable for about a week and when I tried to start it (from battery), it didn't do anything. The battery was still loaded (63%) I have to connect the AC adapter to the power supply to make it work.

Meanwhile the battery LED is always orange. The battery doesn't load, battery power remains 63%. I tried to remove the battery for a while and put it back in, but this didn't change anything...

How can I solve this problem?

Answer:Satellite M70: Battery doesn't work anymore

Hi

Possibly the battery has a malfunction. It would be very interesting to know if this issue happens after battery replacing.
According to your posting the warranty should be valid the battery replacement should be done for free.
I recommend contacting the Toshiba service partner in your country and ask the guys for the help.

Help! So I have a Split X2, that I absolutely love. Well the keyboard completely stopped working. Anytime I connect the keyboard to the tablet, the screen shuts off completely, as if the battery is dead. When I tried charging it, it wouldn't hold a charge. The tablet itself works fine, but it's difficult trying to complete college assignments and work on it, without a keyboard. Now it's to the point that sometimes when using just the tablet, the screen keyboard would freeze up in the middle of whatever I'm working on, and I have to shut it down and restart it. I would like it fix it but I haven't had no luck with any help. Please

My audio will not work when the laptop is on battery instead of plugged in. It's not muted, and I've been through ever battery/power setting i can find, and can't seem to get anywhere...

Answer:b570 audio doesn't work when on battery

hey Dburdz,does this happen when the power adapter is connected but the battery pack is removed ?anyway, uninstall the current audio drivers for your unit. let windows install its generic audio drivers.once generic audio drivers has been installed, test your unit with and without the power adapter and with power adapter minus battery pack.is the audio working ?

Hi,I have this weird problem with my battery indicator. It doesn't work, shows gray battery and three dashes inside instead of the remaining time. The system (Windows 7) built-in indicator works properly however. When I open the Power Manager, it shows some random, impossibly high number of watts used. Each time I open the power manager, the value is completely different.  I haven't installed/updated anything recently, yet a few days ago when I've started the system, the battery indicator stopped working. Restarting the system doesn't help. What do I do now?

Answer:E5 575 brandnew doesn't boot nor work on battery

Hi,It shouldn't do that as it's a brand new laptop, if you can return it for a refund or replacement to the retailer, please do so, you can also get in touch with acer support in your region and get repaired under warranty. If you want to try something to rectify it by yourself, you could do a battery reset after disconnecting from mains(remove the AC adapter), after completing the reset leave the laptop to rest for 5 minuites.http://acer.custhelp.com/app/answers/detail/a_id/34843/~/acer-internal-battery-reset https://www.acer.com/ac/en/US/content/support

Hi,

I'm having some problems with (I think) the Power management utility on my A30. When I'm running on battery power and I plug in the power lead, the battery continues to discharge, even though the laptop 'knows' that it's running on mains power (i.e the utility says "Current Power Source: AC power. On line, discharging: 82%". Strangely, if I put the laptop into 'hibernate' mode and then resume, it goes back to normal (i.e. running on AC power, battery charges).

Admittedly, I think this started after I installed "PC Pitstop Optimize Scan" from www.pcpitstop.com (please, no lectures - I've used a couple of their utilities before and they were fine, so I thought this would be too), so I guess it's some kind of configuration problem, but I've no idea where to go from here. I've been through all the options on the power management utility, but they all look sensible. Any ideas (apart from not installing stupid, dodgy software)?

Answer:SP A30 - battery doesn't recharge when I plug in the power cable

Hi Kenny,

I have experienced this behaviour on my A30 where the system says it is running on AC power, but still drains the battery and eventually shuts down.

In my case the problem proved to be a loose DC plug which occasionally breaks contact with the socket on the rear of the notebook. This momentary loss of DC power seems to cause the power management utility to switch to battery supply even though DC power is restored. The only way out of this situation is to hibernate/reboot the notebook.

I believe that this is a problem with the power subsystem in the notebook which does not react correctly when it encounters a momentary loss of DC power. The Toshiba Power Management utility then no longer reacts correctly and switches to battery power.

My only solution to this has been to anchor the DC cable to the back of my A30 so that there is now no chance of the DC plug moving in its socket. This has proved very successful for my A30 and I have had no recurrence of the problem.

Hello all,I've spent some time browsing and searching this forum to avoid asking a question that has already been answered but I haven't seen a complete answer to this situation so here goes. I have a Lenovo 3000 N100 model 0768DKU.  Battery (P/N 92P1185) started not charging/not holding a change about 6-8 months ago AND the laptop now abruptly shuts down even when on AC power.  From the forum I found out about the 18 month battery replacement policy but I'm just a few months past the 18 months so out of luck there.  Normally I would just buy a new battery but the last few months I've been getting very frequent shut downs when the laptop is exclusively on AC power even with the battery removed!  This has kept me from buying a battery because the laptop won't stay on even when it's plugged into the wall then how will a battery help?  This has really thrown me for a loop since the laptop may run 30 minutes then it's dead like you pulled the power cord.  Turn it back on maybe 10 minutes then dead, or 5 minutes then dead repeat over and over. Steps I've taken since browsing the forums:Virus scans/spyware are cleanUsed compressed air on the fan vent to remove a little dust, opened up and sprayed out dust nothing major.Speedfan is reporting cpu temperatures of 65C to 69C at 99% idle.Reseated memory Questions:Would a new battery potentially solve this problem?  I'm not sure how s...

Answer:Battery doesn't charge AND frequent shut down when only on AC power

Hi.  I had the same exact problem and was disappointed that noone answered.  After further research, I tried a "hard reset" and that seemed to do the trick.  Maybe it will work for you too.  To hard reset your laptop: Turn off machine, remove battery, remove power lead then hold down power button for ten seconds.  Good luck.

My faithful T42's 15" display doesn't go into low brightness mode on battery power. FN brightness keys don't raise or lower the LCD panel brightness in XP with drivers current in sysupdate. I'm on the latest BIOS and EC codes available. I can't say that it's too bright, as it's just right for normal indoor use. You're asking: is it really a problem? I suspect main board hardware. I've set the BIOS to its defaults, and even removed the clock battery to zero it out. It's a bother not to have 100% functionality on this workhorse that has served me so well for the past 10 years. Plus, I think the ATI GPU overheats sometimes which may be causing (rare) system resets. It's a 2379-R9U with the M10-based Radeon 64M. FRU should be 27K9911. I'd probably be willing to replace it if I could find one at a good price. I must say this is/was a great machine. Yes, I'm happy that it still boots up and runs great most of the time.

Hi there,

I've bought a Toshiba Satellite A100-649 in June 2006.
Now, 3 months later, the battery doesn't work anymore.
The Toshiba Powersaver says that it is at 94% of power,
the LED shows that it's loading but it just hangs at 94%.

Well, I wouldn't care if it couldn't load 100%, but here's
what makes me angry:

If I don't have my AC-Adapter plugged in, it doesn't work
anymore. It doesn't boot up or anything. Nothing works.
No LEDs flashing, nothing.

Now what the heck is that? I mean, this notebook is like 3 months old
and the battery is already broken. A notebook without a working battery
is like a desktop-computer without a monitor or something.

So, maybe someone has experiences like that or any ideas what I could do
(except calling the Toshiba support or bringing it back to the store where
I bought it, that's what I already did - Nothing so far, neither from the store
or Toshiba).

Greets,

codec

Answer:Satellite A100-649: Battery doesn't work anymore

Hi

It seems your battery has a malfunction.
Usually the warranty covers the battery for about one year. Therefore in your case all reparations and replacements will be done for free.
In your case I would recommend to contact the Toshiba service partner in your country and explain the guys the situation.
I?m 100% sure that they will help you.

I?m not sure if the service point will need the whole notebook or only the broken battery.
But these details you could discuss with the technician.

Good luck

On the Toshiba website you can search for a compatible charger and the part number:

If you have the part number you can search with Google for this number. If you can?t find something you should contact an authorized service provider. They can order all Toshiba parts.

Hello,

Lately I have some problems with my battery or with the adapter. When I use the adapter (led's working and Power Saver indicating that battery is charging), the battery is not charging, in contrary, it keeps losing power until it gets to 0% and the laptop shuts down!Than the led's of the adapter stay out even when I disconnect and reconnect the adapter. After a few atempts, the led's start working again and the battery starts charging. If I turn on the laptop to quick it shuts down again.
Once I got the laptop up and running again,and if I put the screen in a darker mode or turn of the computer completely, the battery charges again. The Power saver indicates that the laptop is on full power of and uses normal netpower. Mayby the adapter is not working properly?
If I want to change the adapter, where can I find the right model (Toshiba part NO: PA3381U-1ACA/PA-3381E-1ACA) 'caus this one is not available (anymore?) on the toshiba site...

Thanks!

It's a couple of days that my Satellite doesn't want to use the electricity coming from the AC adaptor: it only wants to use the battery (so after some hours it switches off).

Plugging and unplugging the power supply when the notebook is on or before restarting it doesn't change anything (if the battery is still at its place). The AC Adaptor, cable thorns,... seems to be in good conditions and I don't think they have problems because when I take away the battery and restart the notebook, the Satellite finally understands that it must use the power supply and not the battery. Then I can put the battery back at its place and charge it... But if I disconnect the AC Adapter, the circus re-begins.

Is the power supply somewhere disabled? Is there a place where you can choose: "always use the battery and not the power supply"?

I don't think, so, is it a motherboard problem?

Answer:AC adaptor doesn't work if the battery is not removed on my Satellite?

Not sure what specs will be useful so here are the main things: custom built computer inside a "Cooler Master Storm Enforcer" case with an ASRock Z77 Extreme6 motherboard, Intel i7 3770k, and Windows 8.1 Pro w/ media center.

Also as a side issue (that has been going on since before Windows 8.1) when I right click a word in Chrome to auto correct it that only works once per text entry. If I click the new word on the context menu nothing happens.
