laptop screen doesnt turn on untill i press the 9 or 6 key on the numpad.
i'm using the acer predator helios 300. the screen turns on for a brief moment after the power button is pushed showing the predator logo. but after that it just goes blank. when i keep pressing the 9 or 6 key on the numpad, the screen turns on and off until it turn on for good. the laptop keyboard doesnt work after this point except for the 9 and 6 keys and i have to use a usb keyboard. sometimes,the airplane mode gets triggered randomly. the track-pad also gets disabled automatically. is this a keyboard issue? please help.
disconnect the integrated keyboard and try only using it with the external keyboard
> Hello. I have an HP Pavilion 4500 laptop and it won't turn on. I've tried everything to get it to turn back on. There are no flashes or beeps or anything when I hit the power button. Also, before all this came up, my charger wasn't charging correctly. It would turn on then turn off repeatedly. Then one day, my laptop shut off and didn't come back on anymore. I haven't been on my laptop in about 4-5 months now. Could someone please tell me what might be wrong with my laptop?

you havent used it in almost half a year!!!! get yourself a correct charging unit for it that works properly and charge it. leave it out in a warm spot for a day before hand though. it sounds like its gotten very cold internally and also all the battery power has seeped away to nothing. this happens with rechargable batteries after a while. of course you wont get anything when you've got a dead battery. sounds like the charger you have already may be defective or your current battery is defective at least.  

At the other end of the scale though it could be that you laptops power supply unit has become defective and maybe that has blown.  

Rule out the simplest options first of it being the charger or battery. if theres no joy take it down to a local computer engineer and get them to have a look. be prepared to spend a little dosh on it.



btw what r your laptop specs?? might help us.:D a quick fix is to go into the "device manager" Start-settings-control panel-system-device manager and right click on your keyboard and select delete. when it's deleted restart your pc. You will not be able to use your keyboard until it is reinstalled by your computer let it start up and you will see a little come up that wil say something like found new hardware or found new keyboard. after this you should be able to use as you used to You can get seperate dc jacks from here

Try not to disconnect the screen as it may never come on again, i would take to a qualified repairer. It could be a problem with static discharge , if so do the following.


1. Disconect the power cord


2. Remove the battery


3. Hold down the power button for 30 seconds , then release for 30 sec and then hold down for another 30sec


4. Plug in power ,replace battery and power on laptop.


If this causes no Joy try this.


Remove memory and reinstall one stick at a time, if there are more than 1 dimm of ram, try each stick in each slot one at a time to see if the memory is ok and to determine if one of the memory slots is bad.


Hope this helps Are you using drivers released by and/or approved by you laptop vendor? Or are you using later generic drivers from the Intel and Nvidia sites? If the latter, well, that's likely your problem. Go back and test again with drivers from your laptop vendor.

[View solution in original post](/t5/Graphics/Problem-with-Intel-UHD-Graphics-630/m-p/1227288#M91445) timgoos,there seem to be a few threads about this issue. most people, at least those who bothered to respond back to this forum, seem to indicate that turning off the "lock screen controls" resolved the issue for them. my guess is that there's a bug somewhere in the app, and they haven't either figured it out, or looked at it. i'd suggest that you go to settings -> sonos -> lock screen controls and make sure it isn't green (on). it's inconvenient, if you're accustomed to using the lock screen like i am, but then again if it doesn't kill the battery, that's a plus.and if you'd be so kind as to come back and post here to let us know if it works for you, it might help the next person who may be in your shoes.thanks! Hello,  
  
Put in new batteries and try again.  
  
If new batteries did not solve the problem, the next thing to check would be the battery terminal.  
  
If
 the battery terminal is rusty, the battery power won't contact and the 
calculator won't turn on. So, use a flat small screw drive to scratch 
the battery terminal so that there would be contact.  
  
If the above
 is not the problem, the next to check would be the wire connecting the 
battery terminal to the the calculator's main board. There is a wire 
between the battery terminal and the calculator board. When the battery 
is inserted, the power from the battery goes from the terminal to the 
board through this wire. There is a possibility that this wire is cut 
in-between or is loosing contact. In this case, you need to get a small 
screw driver and carefully disassemble the calculator in order to check 
the wire.  
  
If the wire is intact, use a light brush to brush the calculator board as there might be dust on the board.  
  
If non of the above helps, then it means the calculator is dead and needs a replacement.

BE SURE and Save Data before th eHard Reset, it clears all waypoints and such.

Normal behavior is that when you are using a tool, and then press and hold a shortcut key while you use another tool, Photoshop will jump back to the first tool when you release the key.


 


I watched your video, and this is not what is happening to you — you are releasing the keys. Two thoughts for trouble-shooting purposes:


* Can you try another keyboard?
* Can you try with a mouse?
* Have you tried resetting Preferences? This is different from uninstalling and reinstalling. Go to Prefs > General and click Reset Preferences on Quit.


Maybe another volunteer will have other ideas if these don't work.
