Y40 - 70, off when disconnected.

Hello everyone.

I bought a computer from Lenovo y40-70 in early January and so far I really liked it. But just the other day, I started having some strange problems that I am frankly at a loss to solve. It has progressed in several stages, and I'm a little worried about my laptop. I wanted to know if anyone had fixes / suggestions:

1 - the first thing I noticed that the battery icon would not show the 'fill' battery upward while it was plugged. I remember reading that the battery icon is not always refresh, and as the battery said it was in charge, I don't worry.

2 once again, yesterday. After using my computer without the charger for awhile, I plugged it to work. It has been plugged in for a good two hours, and yet the battery continues to read to 17%. He wasn't going to the top.

3 - I unplugged my computer to check the status of the battery. My whole computer cut down (instant, black screen, fans stopped etc.). Turned on while it was still unplugged to watch it reboot fine. Battery was still 17%

4. repeat the process to plug/unplug the computer to find the computer off every time. The battery did wind up filling to 94%, so did not. I finished my work for the day and went to bed.

5 tried to boot my laptop, unplugged, today while I was out. It lights not, despite the fact that I know that he had a full battery before I put it there. I then plugged and tried again. It turns out, displaying an almost total battery. When the computer was still in withdrawal of the plug, once more instantly it turns off. Several attempts more and it's pretty clear I can't use my computer unless it is plugged.

And it's quite revealing of the situation so far. I don't know if it's just a matter of a defective battery or if something else is at work, but I was wondering if anyone had advice until I called him in support.

Thank you!

  • Palm TX turns off when disconnected.

    Recently moved and unpacked and recharged palm tx by usb and connect it to the output.  Works very well so that hip.  Has not added any new software.  When unplugged immediately turns off and only turns on when plugged into the socket again and the soft reset.  Tried soft reset several times and just tried a hard game.  There is no change.  The device has 4 years but otherwise works well with no damage.  Not sure if this is a battery thing, which means that I would have to dispose of the unit or something else.  Was working fine 1 month yet.  Really need it to work in the short term.  Any suggestions would be a great help.

  • HP 15-r011na: laptop turns off when it is attached cable ca

    Hi, I recently picked up the upgrade of Windows 10 and since then have had problems with the laptop switching power, do not know if it is related to Windows 10 but seems a coincidence!  When I got close I use the power on the screen completely closes the button and the laptop.  When I turn it on it's ok, if I have the AC cable disconnected (i.e. using battery power) but if I have the AC cable the screen goes off, but then goes black and seems to have turned off again, and I have to press the power button to put on the.  Also, if I connect the cable so that the laptop is on it goes black immediately, and if I delete it the screen comes alive again.  Can someone tell me what's going on that I have no idea about these things, and it makes me absolutely crazy!  I would really appreciate some advice please.

    Hi @Greenjack67 ,

    Thank you for visiting the HP Forums! A place where you can find solutions for your problems with the help of the community!

    I stumbled upon your post on the laptop and wanted to help you! I looked in your question about your laptop 15-r011na HP TouchSmart and the laptop turns off when it is attached cable ca. Here is a link to test and calibrate your battery for Windows 10.

    Note Remove all USB devices. Disconnect all devices of non-essential, as these can cause some problems.

    Plug the power supply directly into a different wall outlet. Do not connect it a power strip, surge arrester, or secondary power source as this could cause and issue.

    You can try to use the Windows Update Troubleshooter to fix updates that do not come through Windows 10.  Please restart the laptop twice to make sure that all updates are completed!

    Here is a document that shows how update the drivers that do not work correctly with Windows 10.

    I hope this helps.

    Thank you.

  • HP PSC1410 'off' when it is 'on '.

    The printer is connected to a Samsung laptop by usb port. He has been erratic for a week, sometimes black printing OK, sometimes in red, when black is the color required.

    Today, I tried to solve the problems but could not make it past the obvious fact that the printer has been turned off, when he was on. I tried to disconnect and reconnect the usb cable, nothing helps. When you try to reset the default printer, the printer status shows as off. I looked at other solutions to similar problems, but they do not solve this problem. Maybe the printer is tired? Grateful for any help.

    Hi said,

    I understand that you have a PSC 1410 which emerged off the coast when it actually works. I will definitely do my best to help you with this problem.

    Would you be able to tell me what version of Windows you're laptop?

    In the meantime, I suggest that you download and run the HP print and Scan Doctor and see if there are any suggestions to offer.

    Are able to make a copy of a document that is black and it come out completely black, or does it do the same thing when you print from the PC?

    Hope to hear from you soon

    Hello there, Manjunath K P!

    Thank you for joining the communities Support from Apple! Looks like you're having a problem getting the phone to automatic locking. I know that I want my iPhone did not stay when over and have the screen lock correctly. You can, of course, that your Auto-Lock is set up correctly. Your range of choice of automatic locking from 30 seconds to 5 minutes before locking the screen, or you can choose never so that it does not lock. To change the settings, tap the settings icon, click the general button. Tap the AutoLock option and choose your preference.

    If these steps do not work, and you still do not see the iPhone Autolock when you're in charge, you can go to settings > general > reset and then press reset all settings. This removes all the data. For example, if you have 16GB of music, videos and photos, this option will not remove. What this does is actually reset some of your settings to factory default. It is not a complete withdrawal of the parameters. It deletes all of your preferences for Wi - Fi, Bluetooth, do not disturb, Notifications, general, sounds, brightness & wallpaper and privacy.

    Once that is done, go ahead and try to set the automatic lock again and see if it works.

    See you soon!

    But from Word, there is no other choice. I tried the file/Preferences, I tried through the printer settings and nothing we can find will solve this problem? This has recently (last week or two) become a problem...

  • Screen turns black and shuts off when wakes up Portege Z830 - 11M

    Hi all

    Anyone know what could be the reason for the screen goes black and turns off when the laptop wakes up?
    The laptop is Toshiba Portege Z830 - 11 M W7HP, purchased in September.

    The problem started shortly after I bought the laptop, but gradually began with a period of 1-2 seconds black screen whenever I tried to wake the portable computer of fashion 'sleep'. He didn't look like a regular part "blackout" of the wake-up process so I just tried to ignore it, but it started to happen more often recently. It got really worse after two months of use and the black screen two or three times until I'm at the login screen. The error was also difficult to re-create because it was random. Sometimes, the screen went black once sometimes twice or just blinked for a fraction of a second.

    Yesterday, I worked during the day and at night it turned really bad. The screen went black several times, whenever I went back to work after a short break.
    I changed the laptop off when I'm done, but when I turned back on it in the morning, the screen was just black. I tried to use the touchpad, but it is only the screen on the gray.

    Can anyone suggest what to do?

    So finally that cannot start the laptop is Hmm normal?
    It would be interesting to know if this help:
    -Battery adapter and ac removal
    -Press and hold power button do this for 30 sec
    -Then reconnect both sides.
    Turn on the laptop?

    If this is not good enough, you're in trouble I guess its hardware related issue and in this case you must service help

  • Toshiba 32RV635D does not power off when the computer turns off

    Hello

    I inherited a Toshiba 32RV635D. I have a PVR based on linux (Mythtv) connected to the TV via HDMI, connected on a Nvidia GT610.

    With my previous TV, a Vistron LCD Panel at low prices, he would go to sleep when the put PC into hibernation and light up when the PC came back.
    This required no configuration of me, he's done right. The Toshiba TV does not work.

    With this Toshiba TV, when the POR turns off the TV turns off screen but is actually still on - power led remains lit in green.

    Same thing with the other way around - if I put the TV in standby and powered the POR, the TV does not respond and I have to manually put out of Eve.

    I updated the firmware and it has not changed anything, and I can't find anything related to power management in the menus of televisions. I even tried just pulling the HDMI cable to the back of the TV so it has no physical active entry, and yet, it does not fall to sleep.

    The Amazon page for TV mentions the power management features, and I expected from what I understand, it should behave the way she.

    I read a lot on HDMI-CEC, but to use it with my existing kit, I would need to buy an adapter USB - CEC, and which seems a little odd because my previous TV not cheap-as-chips just done this...

    Also, the different uses in linux suggests considers its sounds the right - 'xset q' running when the computer is idle tells me that "the monitor is turned off" when in fact it is not.

    Clues?

    Ricklous, it can be useful if you have a look at the url
    http://www.Toshiba-OM.NET/LCD/PDF/English/Country_Specific/RV635-323742-English-specific.PDF

    If you want to download the manual of the English edition for your model, I have not read through, but it may be useful to you.

    Either by the way, I have the model 32RL900A and find only a VCR plugged into the claims of taking SCART screen every time it turns on while the TV is set to a string of FTA (Free To Air) and then 'hands back' screen when he (PVR) goes out, and this, I discovered, is a characteristic of the system SCART.

    I don't know if this information is useful to you, but hope it helps.

    Dv7-3165dx notebook computer unexpectedly shuts off when the battery is low. Even at 17%.

    This gets really annoying, that I keep losing jobs! Before it used to give me a warning and then Hibernate. Now there is no warning and it turns off without saving anything.

    Help!

    The laptop is a year old.

    I already ran the diagonsitic battery and it said the battery was good.

    OK, I think I finally figured it by changing power options, and I think that the way you reset the battery also helped.

    Here are the parameters:

    reserve battery level (this is when the popup will appear).

    10%

    low battery (this is when the low battery action will be performed).

    8%

    critical battery level (my computer would die at this point.)

    7%

    low battery action: sleep, sleep (this customize to your liking).

    battery low notification: on (hold on).

    critical battery action: sleep, sleep (my computer died already in criticism.)
