I 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?
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.
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.
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 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.
My 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?
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?
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 x64
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.
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).
(full image, click here)
As you can read, no heavy usage. The CPU is stable between 5% tot 20% and the RAM is at 40% to 70%.
Recently, it can't power on. Assuming that it was a static-flea problem, having happened before, I did the "remove the battery & AC power, holding down the power button for 30 secs" solution countless of times. Yet, to my dismay, it still couldn't power on.
I did notice, however, that each time the battery and the ac power were in and the socket power on, the battery indicator and the ac power cord were both lit. With this, I am certain that the AC power cord is working, and probably the battery is as well. I have also tried directly relaying the ac power to the laptop without the battery attached but failed.
I have a HP Compaq 2230S business laptop, but this question could be put to any HP laptop. The fan is constantly running when the laptop is plugged into the power outlet, but as soon as I pull the plug to run on battery power the fan powers down and stops. I re-plug the laptop back in and the fan kicks up again.
This is not good as I almost burned myself when I picked up the laptop after an hour sitting on the table on battery power. The hard drive is right beside the processor, so the laptop gets really hot.
Vista x64 Ultimate is what I'm using at the moment and my power scheme calls for 1% minimum and 100% maximum CPU on battery power.
Last Friday i received my new Studio 1749 with i3. As told by the documentation I put in the battery, put the power cable in the ac-adapter, pluged the AC-cable into the laptop and then pluged the ac-adapter into the wall outlet. I booted the laptop and once I was on the windows desktop had a look at the battery symbol. It showed that the laptop was connected to external power and that the battery was being charged.
I wen't away from the laptop to let it charge the battery for 12 hours as told by the documentation. After two hours i came back to have a look at the laptop and it was off. Curious I turned it on again. After booting up it showed the battery at 60% and the laptop running from battery. Yet the ac-adapter was connected to the laptop. I hadn't changed anything. I pluged the adapter cable in and out, but it wouldn't recognize that the was external power available. Turning the laptop off an on again didn't work either.
Now I feared for the battery. My guess is that at one point it started to run on battery power even though it was not charged for 12 hours. Then when the battery was depleted the laptop shut down. This might have permanently damaged the battery!
I guess as soon as the laptop was off the ac-adapter charged the battery again, and when I came in it was just at 60%.
So I turned it off removed the ac-adapter, removed the battery, put the battery back into the laptop pluged the ac-adapter back in and booted up again. Now it showed it was running from external power again. All fine. It charged the battery as well. Actually it charged the battery up to 99% and then out of nowhere the battery symbol changed and it was running from battery AGAIN! Even though it was still connected to the ac-adapter. This happens all the time. It is reproducable.
So I thought something might be wrong with the ac-adapter.
I powered down the laptop and removed the battery. Now with only the ac-adapter connected ,I tried to start the laptop. The control lights above the keyboard came on for 2 or 3 seconds and then the laptop turned off again. Trying to hit the power button again after that didn't give another reaction.
Conclusion: The laptop won't run just on external power with no battery in the battery bay.
I put in the battery again. AC-adapter still connected. Hit power. Laptop starts to boot. Then while booting I removed the battery. Laptop keeps on booting - finishes booting - runs nice and well at full speed not missing the battery - FOREVER.
So it won't boot with the battery removed, but it will run without it flawlessly??? Strange isn't it?
Next test: I put in the battery again while the laptop is running from mains. And now it charges the battery again until the point... you already know... it "forgets" that it is connected to the ac-adapter and starts running on battery power. So now I boldly removed the battery while the laptop was running. After all it was still connected to mains/ac-power.
My battery on my acer draws power at times when my laptop is plugged in it will work ok then the on and off button will start to blink It will go into hibernation when plugged in when the battery gets to low....
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!)
When I pull the power cord to switch to battery power while in Windows my lcd goes to black. The only way I get my video back is a hard reset and reboot. Later on I tried this and everything was back to normal. Why is this happening? Is this some weird standby?
Our Studio 1749 will retain a solid connection when the power adapter is plugged into the power board along the side of my laptop. I am unsure if the pins residing in the power board are pushed toward each other so as to not retain connection when the adpater in plugged into the laptop.
After replacing the fan, I have a power up issue with the laptop. Basically, the laptop will only power on with the power cable disconnected at the motherboard. It was by mistake that after the fan was replaced and everything was put back together, that I noticed that the battery was not charging.
I then reopened the machine and reconnected the power cable to the motherboard and nothing - no power.
When plugging in the power source with the battery in place, the LED adjacent to the power socket lights up WHITE then stays ORANGE and will not power up. No other lights, no fan noise, nothing.
If I remove the battery, the LED adjacent to the power socket lights up WHITE and stays white however will not power up either. Same agin, no other LEDs, not fan noise, nothing.
I have now opened the machine back up and disconnected the power from the motherboard. Put it all back together and the laptop powers up as normal with the battery and it works fine. (Well until the battery runs out anyway).
Acer 5253 - Will not power on, battery or on AC power. Have tried all the suggested solutions but none have worked. Is it possible to get maintenace instructions (disassembly, where certain items are located, etc)?
Last 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 .....
Am using N5010..Windows 7 Ultimate.I already used the Bluetooth mouse ,now i tried to add the Bluetooth mouse using add device but the system cannot find the Bluetooth mouse its keeps on searching. Mouse works fine in other systems. Its Belkin mouse
I have a year old DV9774ca with bluetooth. I never used it. My wife has a Toshiba laptop without bluetooth and wants to use a bluetooth mouse. Can I take out my bluetooth adapter and put it in hers? I have not seen or handled one before.
Its ays its a HP Integrated Bluetooth Module. The "integrated" doesn't make it sound as simple as I hoped!
Im using a dell inspiron 14r(5421); intel core15 3337u: intel Centrino 2230 wireless Bluetooth driver.
when I pair my phone (HTC Sensation) with my laptop I can only see the option to share files and transfer PIM objects. There is no option whatsoever to stream audio or to use my laptop as a headset. I had this option in my windows 7 acer laptop but that was using a Broadcom driver for Bluetooth..
I recently purchased a Dell B120 used in ebay. Laptop worked great on AC adapter, but battery showed 1% on battery indicator and would not work. I ordered a non-dell replacement from a company on ebay. Battery came in and had 94% when installed. Just to check I unplugged AC adapter.
Laptop seems to work properly for the few seconds I checked. I then replaced AC adapter cord and allowed battery to charge overnight. Next morning I powered up laptop and checked battery power.
Laptop showed 100%, so I pulled AC adapter plug. Boom, nothing, no power. I have tried everything to get this battery to work. Bios sees battery and shows no battery when removed.
Bios we upgraded to latest dell upgrade A08. Battery info in bios says battery performing normal. shows 100% but no power .....
