View 6 RepliesI was thinking of purchasing a Dell XPS 1530 for college. I have everything customized exactly the way I want it but I was wondering if the bluetooth option was absolutely necessary for college campuses? I really do not want bluetooth in my laptop if I do not have to get it as I hear bluetooth drains laptop battery power, but is it required by todays standards?

View 8 Replies View RelatedMy E530's battery drains 5% per day after power off. I searched online and somebody else complained about similar issue on his Y-series laptop. His problem was solved by plugging off power cord before turning off the laptop. Lenovo also updated BIOS regarding this issue for his model after then.
Yesterday I tried his way and the issue was gone too. Can Lenovo update BIOS regarding this issue?Â

I also find the power manage scheme doesn't work. It always charges the battery from 96% to 100% in whatever scheme I chose. I tried to uninstall the driver and downgrade the power manager, still doesn't work. I didn't try reinstall the system because it is too time consuming. Does it matter I installed win7 in my SSD?
i have a compaq c500 (c501tu) laptop.
for about 6 months now when i run the laptop on battery power it dies after 15 mins.
i thought i needed a new battery but tested my existing one on my friends laptop which is the same as mine, a c500 series.
after fully charging the battery on my laptop i removed it and plugging it into my friends laptop and it gave me 45 minutes of power compared to 15 minutes on mine!
i did this thrice and had the same results. but when i plug it back onto my laptop i get only 15 minutes of usage.
Lenovo Carbon X1Bought ~2 months ago (new) at a reseller in the USi5 3rd generation @ 1.7GHz4GB DDR3 (soldered on motherboard)128GB SSD (Samsung), must be SATA III (6GB/s) I guessWindows 8 Pro x64Â
Furthermore:
+40GB free space on the hard drive Original charger used, always . Laptop was never 'opened' (ie with screws)device mainly used to text editing, browsing and PhotoshopBackground apps/services: Apple iTunes services, Dropbox, Lenovo mouse/trackpad service and startup utilities like Google Update, Java update, Adobe Reader Speed launch.
I do not shut down my laptop most of the times, I simply put my computer in sleep modus (in other words: I close the lid of the laptop)I do play games on this laptop, but of course I do not expect the battery to last many hours when doing so. The battery drains quickly only in 'normal' situations - gaming, video editing and lots of Photoshop do not count of course.Connected to the internet all the time (no 3G, just WiFi)Bluetooth disabled.Â
The laptop is fully charged using the original charger. The power plan is set to Power Saver (image). Brightness is set to around 60% of maximum according to the build in indicator of Windows 8. The apps that are open are Google Chrome ( with 5 tot 15 tabs most of the time), Outlook, Dropbox and one metro apps (weather or the app store).

As you can read, no heavy usage. The CPU is stable between 5% tot 20% and the RAM is at 40% to 70%.
I just purchased a new probook 4540s core i5 with win7 x64 system.

Firstly, When battery full charged then turned laptop off for a few hours or next day it becomes 99% or 98% although its plugged in Ac power. Shutdown again for 1 hour and turn on it turns to 97%. Is that ok or there is problem in battery specially it shows that ( Plugged in, Not chareged ) so laptop should operate at AC adapter and battery remain 100%. Secondly, I have an unknown device can't find it as shown in figure below.
I have my lenovo x230 laptop set to sleep when I close the lid. When I close the lid the "sleep" icon on the back of the screen lights up. But the batter will not last through the night on sleep mode. Within five hours or so, the battery is completely drained and I have to plug in and boot up the system. I've never seen such poor batter performance during sleep mode on any other laptop I've ever owned.Â
Â
Another thread in this forum blames the USB port that allows you to charge mobile phones/etc. during low-power states and recommends disabling the "always power on" option fo this USB port in the Bios settings. At least my laptop still will not make it through the night in sleep mode.Â
Â
At this point, it seems my ownly option is to use sleep mode only when the laptop is plugged in and hibernation mode when on batter power, which is disappointing. I've never had to worry about this in the past with other laptops. Perhaps/probably related is the fact that the lenovo ThinkVantage Power Manager (v. 7.16) hangs at the splash screen when I try to open it, so I've been trying to manage the power through the windows control panel power settings.
I want to turn Wi-Fi and Bluetooth to save the battery but I can't find the way to do it. There is no button or smth like this. How to do it?
View 5 Replies View RelatedI bought at DELL OUTLET a M6400 without the Bluetooth Module, I will buy it separate from DELL, do you know if the Bluetooth antenas will be Pre-Wired in the notebook ?,
actually I am buying the DELL 410 Bluetooth + UWB card, meaning I need the Pre-Wiring for Bluetooth and UWB ?
I noticed a few other threads around the internet about this issue, but couldnt find a definitive answer on how to get it fixed, so I thought I would try it here.
The problem is that when I go into standby and wake from it, my bluetooth icon disappears and bluetooth doesnt work.
I have a Dell Studio XPS 13 running Vista 64 with the Dell bluetooth 370 minicard. Ive tried using the generic windows bluetooth drivers as well as Dell's drivers.
Nothing appears in device manager as well. I have to manually go into bluetooth settings, disable the device, then re-enable it.
My Bluetooth keyboard goes to sleep after a period of idle and it takes 15 seconds for the Acer Aspire 1810T to wake up and notice the Bluetooth keypresses.
However, I found out my Bluetooth keyboard works reliably when I have a second Bluetooth device connected and active at the time (such as either a headset or bluetooth tethering to a cellphone as modem), the computer doesn't have a 15 second lag in noticing the Bluetooth keyboard again - the keyboard works almost right away even after being unused for sometime.
So that means the culprit is in the power management on the Acer Bluetooth module. Is there a way to force the Bluetooth module to never go to sleep? Any checkbox somewhere, a register setting? Even going as far to purchase a different Bluetooth driver? Or any other option? Sometimes the sleep is useful, but it definitely isn't useful with the Bluetooth keyboard. This problem does not happen if I use an external Bluetooth dongle.
(With BatteryBar Pro, I notice that power consumption falls suddenly whenever the Bluetooth module goes to sleep when the keyboard goes idle for more than 30 seconds, and at this point, it has difficulty 'waking up' when I start typing on the Bluetooth keyboard. But the problem also still happens when the laptop is plugged in!)
I have finally tested the Acer Empowering Technology software on my Acer D150.
Great news, the software works to enable/disable the Bluetooth module on the netbook without physically pressing the button. This is great for people like me that do not have the button on top to push the button inside. There are two software needed for people to get this running on the D150. First is the required “Acer Empowering Framework” software and the second is the “Acer ePower Management.” Once both software are installed on the system, the setting to enable/disable the Bluetooth module is in the ePower Management.
Power profiles within windows will probably be reset to default, so those would have to be readjusted if a user changed them. I am actually running Windows Vista on my Acer D150 with the Acer Empowering Technology software for Vista. I am not 100% sure if the software will also work on XP, but from the notebookreview forums, I believe it should work just as fine (but more options on other Empowering Technology software).
(in XP, the driver also works, but need XP edition, not vista editon).
I have need to use Bluetooth stereo audio functionality (A2DP profile) almost exclusively when I use my laptop.
I had owned a M1330 with the Dell 355 Bluetooth Module for several years without issue. Last November, I decided to upgrade and purchased an M15x (laptop #1) with the Dell 370 Bluetooth module included,running Windows 7 x64 Ultimate. Not more than one day out of the box,the 370 module failed while watching a movie. It literally disappeared from device manager and no uninstalling/reinstallation of drivers alleviated the situation. The only way to get the radio to be recognized by the operating system was, and is, to shutdown,reboot into bios,disable the card in bios,reboot into windows,restart,boot into bios,enable the card and then reboot into Windows. The card would then work for awhile but eventually fail again. The module works for short periods of time but if put under an extended load,fails. That and other issues with the M15x caused me to return it.
Contacted Dell and returned the M15x and bought and built a Studio XPS 1645 (laptop #2) to replace it. Received the unit and literally within the 1st few hours,the 370 module failed exactly like the M15x.I thought o.k. a bad card and had tech support send out a new module for the XPS 1645. Received and installed it and the exact same problem happened. Failed when under an extended load. Again called tech support and was then dispatched an onsite tech to replace the entire motherboard and card. No resolution-card failed again. Spoke with a resolution specialist and returned it and again purchased a M15x (laptop #3-really liked the M15x over the XPS 1645)
Received the M15x-Bluetooth failure again. At this point, was considering dropping Dell altogether but thought I'd try the Studio 1558 (laptop #4) with the Bluetooth 365 module, in order to rule out the 370 card, first. Ordered and was delivered on the 5th of April, same exact issue-failure of card under a load. I am returning this defective Studio 1558 and again getting a M15x (laptop #5). I realize that the M15x Bluetooth card will fail again-in fact,am 100% sure it will fail,but have bought a Sony Bluetooth transmitter as a workaround.
What appears to be happening is that the card will shutdown when it gets warm.This is either a Broadcom manufacturing defect or a Dell engineering issue. I know now through personal experience that there is a serious issue with Dell Bluetooth cards.
If this was happening with only one laptop, I'd be ok with it but, this is occuring across multiple laptop platforms, with both Broadcom Bluetooth cards that Dell brands and sells.
This is either an oversight by engineering-maybe they didn't test the card under a heavy load, or Dell is knowingly selling defective equipment.
I have a dell xps m1710. the battery isnt working and vista shows it as no battery is detected. bios shows it not installed, my question is it safe to keep the bad battery in the computer and just use the ac adapter?
second question.
my wifi led is blinking, is that normal?
Refurbished Laptop - latitude E6410. The battery light contrantly flashes on the Battery five or Six solid blue lights - Then three flashing lights.In addition, the Light on the Computer (  ) and the desk top icon for the power adaptor cord /battery says" Plugged in - Not charging".I ran the Dell Diagnostics (Fn key at bootup) but it found no problems.is the battery dead?Â
View 1 Replies View RelatedLast night I was using my E1705 running on battery when the thing just suddenly zapped off. I had recently glanced at the battery meter which was 75% full. I pressed the button on the actual battery which shows 3 of 5 lights on the charge meter.
The battery itself is only 1 month old and has been performing flawlessly. I just thought it was something random so I plugged the machine in and it started up.
I didn't think anything else of it till today when I went to move my laptop, removed the power cord, and the laptop turned off. I checked the physical battery meter which still reads 3 of 5 lights .....
My Dell XPS 15z is showing the following problem :-- if I try to boot it with the battery connected (and AC power either plugged in or not), the orange power light flashes briefly and then the machine shuts down- if I remove the back of the case, disconnect the battery, connect the AC power cable and boot, the system boots as normal
Other observations
- BIOS version is A07, I can not upgrade this to A12 as, when I try to with the battery disconnected it basically tells me I have to have a battery connected to do the upgrade- when I click on the battery status button on the side of the case with the battery connected, one LED lights- when I click on the battery status button on the side of the case with the battery disconnected, no LEDs light
What are the next diagnostic steps?What is the likely fault - could replacing the battery unit solve the problem or is is the component which charges the battery which is likely to be faulty?The laptop is 18 months old but only covered by a one year warranty with Dell.
Been using XPS15 for just over a year and am getting a "battery has permanent failure - need to replace battery" message....
I've rarely even used this current laptop without using power, so the battery seems to have died a bit too soon?
Is there a particular Dell battery I can buy that should last a bit longer?
Can I use the dock battery of my Dell xps10 before the battery inside the tablet?
View 1 Replies View RelatedI've run into this issue twice already... once on 1 computer and another on this same one. It's the one where the battery is not recognized and there is an "X" where the battery icon is.
I've done all the Software Updates, Batter Update 1.3, and tried resetting the PRAM. So far none of these have worked. Now I'm out of ideas. Before after going thru those steps, the problem would be fixed... not so this time.
I know they extended the warranty and were replacing the batteries for free, but not sure this one would be covered under that.
I would like to ask about the Lenovo Energy Management software bundled with my Z400. Regarding the Energy Management > Battery > "Optimized Battery Health" in particular. When the battery charges until 60%, does it internally disconnect the charger from my battery? The Power icon in the System Tray says "Plugged in, not charging". Or does the software stops the charging until 60%, and when it lowers the software allows it  to recharge again? I'm worried about getting my battery worn out immediately, as I leave my charger plugged in most of the time.
View 1 Replies View RelatedMy 2 day old Lenovo Y510P laptop has a problem with charging. I noticed the battery was never going above 60% charged. I left it plugged in for over 24 hours and nothing changed. So I decided to completely drain the battery and used the laptop until it died. With the laptop off I left it plugged in until the battery LED turned white which indicates the battery is fully charged. Unfortunately the battery still shows 60% charged.
View 7 Replies View Relatedi am using acer aspire 5600 xp/vista and LION battery.
my battery had memory effect once and could work for like 15-20 min.but its indicator worked fine at that time.
but now memory effect is gone and i am now facing a new problem.
At full charging, system shows that battery is not connected even it is connected.even if i unplug the AC supply still it thinks that notebook is running from AC supply.During this period i cant use my laptop keyboard and touchpad.I Can use only externally connected keyboard and mouse.
While notebook is using the laptop battery(Ac Unplugged),after sometime it detects the battery and the indicator shows 7% of battery time.Then my notebook keyboard and touchpad starts to work and then this percentage decreases to 0%. The time between shift of percentage is approx 10 min . Even On 0% the battery works fine and works for like 15 min. Overall Battery can work for like 1 hr 30 min approx(Low Performance).
My main problem is i cant use my laptop keyboard and touchpad while the battery is fully charged. i have to drain my battery in order to use keyboard and touchpad.
recently i bought a new HP g60 laptop. now i am wanting about the main differences of original and aftermarket battery for HP g60 laptop.
View 5 Replies View RelatedI just received my MBP 13" yesterday. So far I love it. However, I noticed an issue. Last when I put my MBP to sleep, it had about 30% battery left. However, when I woke up this morning and opened my MBP, the battery went down to 13%.
When I put the laptop to sleep, I had a pdf file open along with itunes (paused). I have never used Mac OS, so maybe I not doing something correct. Also, I noticed when I open the lid (after I put the notebook to sleep) it just goes directly back to the desktop as opposed to on windows it prompts to the login screen when waking it up from sleep mode.
My Dell inspiron 6400 has a battery that works amazingly but recently, I noticed a change in the behaviour. Anytime I switch the laptop on, the LED battery indicator shows me red meaning something is wrong even when the battery is fully charged. The battery charges normally even when I intentionally drain out the power and try charging it again. This is just to make sure that the battery charges fine. Infact, in windows, it shows me that the computer is on AC power even when it is not plugged into an AC outlet.
The BIOS shows "No battery installed" and windows tells me the same. Summarily, everything is fine except for the LED indicator showing Red and the BIOS telling me that no battery is installed.
I am looking into getting one of the new macbook pro's. Though I must say the non removable battery does concern me a bit. In past laptops I have had, I without a doubt saw increased battery wear and tear when I left the batter in the laptop while the laptop itself was plugged in. I completly destroyed a battery on my Dell laptop by doing this for about a month when it was asking as a desktop. I took the laptop which used to get around 4 hrs of battery life and then after a month it got no more than 15 minutes.
So after that I always took the battery out, so now with the new macbook pro's you cannot take the batteries out, so wont the batteries wear down to nothing faster than if you took them out when not using them?
I have experienced a strane problem with bluetooth. Generally it works fine, but sometimes when I connect some some kind of device (Nokia 6300 phone) and after some time turn off bluetooth(the switch on the right side) without turning of bluetooth in the phone, the whole BT module in Vista just hangs. The BT icon is available but no BT adapter is found (the system does not recognize the Dell Bluetooth Module) and it does not help to turn on and off for few times. But the worst is the fact, that after the BT maodule hangs i cannot turn off or suspend the computer. It just hangs at the Shutting down screen forever the only thing I can do is to turn it off by holding power button for longer time... When I first disconnet all BT devices and then turn off the BT module everything's OK and no other problems occur. Is this a driver or hardware issue ?
I have XPS M1530 with Vista SP1 (all updates applyed)
