Yoga 720 power and charging lights

Q: Yoga 720 power and charging lights

I often charge my Yoga 720 at night and annoyed by the blinking lights on the sides of the laptop. Is there a way to turn off both the sleep mode light on the power button and the charging light on the other side, or either of them separately? Thanks.

So I had my yoga 920 conk out on me at a VERY inopportune time, next month I go abroad to study. Yesterday I started my laptop and started some light browsing when it suddenly shut down. I tried starting it up again, when it came up with the dreaded blue screen saying 'failed to detect boot device' or something. Third boot try onwards, the laptop does not respond to charging, no lights come on, nothing, NADA. Worst part of it? This happened within 10 months of my purchase from USA. I have 54 days of my warranty remaining. I tried static discharges multiple times, no luck.Went to multiple service centers in Pune, India, but they refused to diagnose the issue saying that they do not service this model since it was not released in India. I'm ready to ship this laptop to the USA with my own expenses to have it fixed or replaced, but so far no customer service has been able to help me out.Any bright ideas/contacts?

Hello,

I have one of the newer model Dell Inspirion laptops. How do I turn off the light that accompanies the power button and the charge light on the front. I'm able to turn off my backlit keyboard, but these two other lights are quite bright and annoying when I'm trying to play movies in a dark room. 

A:Laptop lights (power/charging) - Dell Inspiron

Hi DELLUSER16486,
What is the exact system model?
The power led and the leds on front are also used as diagnostic indicators. If there is any hardware issue on the machine, these leds help isolate the source of the issue. Hence, there is no way to disable the leds from turning on, as they would be connected to a cable soldered to the motherboard.
Download the service manual / specifications for a better understanding of the machine - http://dell.to/1n3X2po - enter the service tag and download it from the Manual section.
Write me a private conversation with the service tag and your contact details(Name and Email) for case records.
Let us know if you have any other queries.

Currently have a Lenovo W530 that won't turn on. Right before the laptop "died" I was doing work and it was plugged in and then it suddenly just turned off. When I plug the laptop in the charging indicator light does not turn on (nor do any lights). Here is what I've attempted:Removed the battery and unplug from power and hold the power button for a minute to dissipate any charge that may remain. Then I just plug in the charger and try to turn the laptop back onPurchased a new battery chargerIn both cases nothing has changed, it seems like the laptop is just dead. My next attempt would be to replace the CMOS battery but I feel like I should be getting some sort of response from the charge being plugged in, regardless whether or not it needs a new CMOS battery. Any suggestions? Thanks in advance.

after I installed the latest firmware update (2XCN38WW) for my Yoga 710-14ikb, the battery indicator is stuck at 50% regardless if on battery or plugged in. It worked just fine a week ago with more than 7h of battery life.  Now, When the PC is on battery it simply turns off randomly after a few minutes, but works normally when plugged in. When connected to AC the power LED is off, but the PC does make the beep sound when connecting or disconecting the charger.  I used the diagnostics tool and the quick test indicates the battery is good. I cannot perform the discharge test because the PC turns of randomply and the charge test does nothing as the battery level is stuck at 50%. I tried reflashing the bios with 3 different images but every time I get the battery not detected message in the flash screen.  The pc is stuck at 50% battery and turns off randomply when not connected to AC.

Hi geminihc!
 
Thanks for posting in our community
 
As per checking, this model Yoga 720 does not have power delivery (a protocol specification which supports power delivery up to 100W of power while transmitting data in a single cable. It's designed to be a more universal charging standard that allows a range of devices (not just smartphones) to charge quickly over a USB connection) reason why the phone will not charge.

Hey Community, I'm in dire need for help, my lenovo Y50-70 has been working fine for the past 3 years now and JUST after the warrenty is up, my battery becomes funky. I noticed that whenever I load up a game, the charger becomes unrecognized and instead of regular led lights, i get one blinking white light and one blinking orange light. When I remove the AC adapter and plug it back in, it'll recognize the charger and ocasionally it'll take some time to recognize it. It stops charging when the LED lights begin to blink. I've tried to1. "remove the static" or drain the battery by unplugging the AC adapter2. holding down the power button for 30 seconds (I didnt remove the battery because it's not a removable battery, Should I?).3. Changed the power settings to high performance and no conservation of power.4. I bought a new adapter and it's still happening, I have no idea what to do. Intially prior of buying a new adapter it drained and I couldnt figure out a way to get it to charge. With the new adapter I was able to charge it till full, but when I have it on, it does the same thing.  Please help me community, you kind souls. Best,Richard

Hello,My HP Envy 15 laptop started having this an issue about 2 days ago. I was in class and it was plugged into power when suddenly the computer crashed. No warnings, no shut down screen. it just instantly turned off. Unfortunately, it is a few years old and the warranty expired in January this year. I had not done any hardware upgrades/changes it was completely out of nowhere. I then went home and plugged it in. There was no power charge light beside the power cord on the side of the laptop, however I came back 20 minutes later and there was a white charge light. I then powered it up and was on it for about 10 minutes before it crashed again. It is sitting on my desk now on charge. no lights on or anything and it won't turn on. I have tried turning it on just on battery power, I have tried just on ac power and none will work, Any suggestions would be much appreciated

Hi,
I picked up this Alienware 5700 off ebay to hopefully refurbish for my son but I'm new at this and still learning and so this thing has me baffled. The laptop is in pristine condition but shows no signs of life. When I plug in the power supply the green light on the power supply goes from solid green to blinking rapidly to the point you can barely see it. To me that would mean a short somewhere right ? If so where ? Has anyone else ever had experience with something like this ? I just don't want to go buying a new battery for a laptop that maybe fried already. Any help would be greatly appreciated.
 

A:No power, no lights but green light on power supply blinks rapidly

Remove the laptops battery and try the AC power only. If the green light does the same, it still could only be a bad AC adapter, or at worst, a shorted laptop motherboard

Since it's inspiron 15z 5523 Ultrabook from late 2012 I cannot go down to the battery easily. The laptop has never been opened.except for changing ram that too 2 years ago

A:Inspiron 15z 5523 Ultrabook not turning on, Not Charging,No lights,No sound

Unplug the system, disconnect the battery (remove the base cover to access it), and hold the power button for 30 sec.
Verify that the LED on the adapter or DC plug is ON before you continue.  If it's not, the adapter is bad and will need to be replaced.
Remove and reinstall both memory modules.
Power on on AC only with the battery disconnected.  If it will but won't with the battery in place, the battery is bad;  replace it.
If the system still won't power up, replace the mainboard.

Hi Guys, I have had to change my battery, got a brand new DELL battery but I can't get it to charge...I'm running Windows 10 PRO. I have tried the fixes listed above but unfortunately NONE has solved my problem. Any suggestions?

A:XPS 12 9Q23 Power Charging Disabled / Plugged in, NOT CHARGING

Hi DAEMONROD.
Where have you purchased the battery from? Does the old battery charge fine when plugged in?
Are you using an original Dell OEM Adapter? When you plug in the adapter to the system, does the adapter stay firm or does it fall off easily? Is the adapter frayed? Is there any damage on the system? Could you test with another power adapter if possible? 
Restart the system and press f2 key to enter BIOS - check the adapter status in BIOS with and without the adapter plugged in. Also, wiggle the adapter cable at the end and see if the status changes in BIOS at any point. Check the battery health in BIOS (if applicable).
Restart the system and press f12 key on startup - choose diagnostics. Let it run the diags and if you encounter any errors - make a note of the complete error and report the same to us. These are onboard diagnostics and they might possible pick some error if the hardware is not functional.
Test another power adapter and check. If the adapter fits in loose, then the dc port needs to be replaced. You would need this part.
Also, please click my DELL-username and write me a private message with the service tag and your Name for case records.
Let us know if you have any other queries.

Came home, walked in and noticed my PC was off. monitor was on, speakers on, modem everything on as if the power had blinked out for a sec and my system had shutdown. I pressed the power button on the front and got nothing. i checked the power supply's own power on/off switch on the back and got nothing. no light that its on or anything. thought maybe it was the cable so i plugged it into my other pc and the cable works, so i'm thinking maybe the psu went bad or took a hit. Im guessing i just need to replace it. How difficult is it to replace it by yourself. i've never done that before and do you think that its the psu at fault? I'm thinking that if there is not power on light, then something is wrong big with it. my heat temps stay down between 28C and 34C at the highest. Also, can i replace it with just any other 600w power supply or does it need to be a specific kind. company i bought it from online listed it as dual core certified 600w psu. no mention of 12v rail or anything else. i guess i can get that from them if they have it on file.
 

A:No power to Power Supply, no lights

Well sounds like your power supply took a power surge. Well to start with i would try a power supply. Now about replacing the power supply cheap is not the best way to go, learned from experience. Here is my recommendation: http://www.newegg.com/Product/Product.aspx?Item=N82E16817139005
And for replacing a PSU not hard. If you need help removing it Post back i will walk you through step by step if need be.

I have a Compaq F500, and when I turn it on, the power button, power indicator, and Wi-Fi indicator all light up, but the screen does nothing, and after about 30 seconds, it restarts, and it's as if it is just failing to start. If there is a way to just wipe the hard drive without having to boot up the computer, that would be a great help. Also, I don't really know that much about hardware, so elaboration of anything an inexperienced person wouldn't know would be helpful, too.

A:Power on, lights up, screen does nothing.

It sounds initially like a bad Motherboard, But that's only a guess as many other things could be causing this. First, I would want to know if you had any Viruses lately, or if the unit was dropped recently. Sometimes viruses can wipe the Boot Sector of the Hard drive, while this is rare it's worth considering. Does the screen appear to be illuminated at all? If it illuminates without booting, the screen is probably not bad and this is what I expect from what you're describing.

You'll want to approach the issue as an over system problem at the motherboard level, possibly at the hard drive level. The main thing is, you want to see the familiar boot screen before moving forward.

It's possible too that your laptop has a bios reset Jumper on the motherboard, yes that's inside the case of the laptop. Don't try to fix it yourself unless you're comfortable trying this. And, if you do, make sure to properly ground yourself.

If it were me, I'd try disconnecting the hard drive and attempt to boot from a CD. If you still get no screen activity it could be the Motherboard or screen. Motherboard would
be likely bad if this method proves that the system continues to reboot. Keep in mind that Bad ram may cause the unit to reboot also. If it's bad Ram then you might just have to replace that for a low cost without having to pay for service.

Check out these things and report back.

Josh*^ - the lights could not possibly be pulling more that 10 watts, at an extreme. Probably they are actually pulling a level that you could not notice before-and-after if you used an actual measurement, such as with the Kill-A-Watt.

Same for fans, and most anything else you plug in or on except video cards.

Everyone: you will spend all kinds of money to have powerful components, and a suitable power supply - so go ahead and get an ACTUAL power draw measurement -

The kill-a-watt is simple to use and read, very simple. it costs $20 or $25.

You can use it on anything you plug into a 120 volt outlet. Vacuum cleaner, hair curler, radio, anything. It tells you exactly how much power is being used. Exactly.

For over a decade, these power calculators have been estimating power needs, and they have been over-estimating by 100% the entire time.

Hi all, I have a T400 from early '09. It's been a fantastic laptop, though I now only use it for when I travel. Over the last year it's been running very hot, especially when playing games. I've been using a portable fan to cool it down, didn't think about getting it checked out because I didn't use it very often. Today it froze up and I force shut it down by holding the power key. When it rebooted it ran a disk check (I had a sleep and didn't see the results) and when it loaded windows it was running extremely slowly. After a bit of experimenting I worked out the wifi and switchable graphics drivers weren't working. I was able to get it to a usable state by disabling the discrete graphics in the bios and booting into safe mode. I was going to reinstll the drivers. While they were downloading I tried to re-enable the discrete graphics (in the bios) and booted. However before I got to the boot manager screen, I got a BSOD (c000021a). I turned the laptop off, but it would not start again. None of the lights on the laptop are working, even though it is plugged in. The only things I changed in the bios were the switchable graphics (which I changed back to the default setting) and the "beep" on hibernation. I have no idea if the battery has any charge, it should be at 100% as it was plugged in the entire time.

We would also suggest you to drain the residual power from the laptop:
* Disconnect any external peripherals (flash drives, printers, external hard drives) from the computer.
* Remove the adapter and then the battery.
* Press and hold the power button for 10-15 seconds.
* After draining the residual power, try reseating the memory and see if the system is able to boot.
Please private message us the service tag of the system along with your email id.
(Note: please don't mention the service tag or email id on the public forum as it contains your personal information).

RELEVANCY SCORE 50.4

Hello: Just received a beautiful W530 Laptop - love the T and W versions of this machines. However, with such a large power requirement, want to make sure that I will be able to run and charge the W530 on United Airlines, American Airlines, etc., using the supplied 170 W Power supply...  Please confirm your experience that this will work. Otherwise, using this laptop on long haul flights will not work.

RELEVANCY SCORE 50

Hello, my T500 does not turn on, no lights are lit, battery not charging. I tried to turn in the dock, but nothing. I tried to insert a fully charged battery but nothing too. Will probably be something wrong with the motherboard, maybe some fuse, but do not know where to look. Thanks for help
