As with all electronics, you may experience some issues over time due to software updates, drops, or just normal wear and tear over time. Sometimes fixes can be as simple as changing settings on your computer, but other problems, such as hardware issues may not be so easy to fix. Either way, we will try to make this process as simple as possible for all users.
Laptop Will Not Power On ¶
The laptop is unresponsive and does not show any sign of power.
Bad Battery ¶
Your Battery may not be supplying enough power for your laptop to power on.
Make sure your battery is charged. Otherwise, your battery may have a bad cell. Plug in your laptop to a power source and see if you can start it on auxiliary power, otherwise you may need a new battery or charger.
Software Glitch? ¶
Sometimes there are software glitches that can be solved with a little techie touch.
Unplug the AC adapter and take out the battery. Push the power button 10 times in 1 sec intervals. Next, Push and hold the power button for 30 seconds. Replace the battery and push the power button, it should turn on!
Blank Screen at Startup ¶
Your laptop powers on, but nothing comes up on the display screen.
Force Restart ¶
Sometimes part of the software freezes up and needs a fresh start in order to free itself from problems
Force turn off the laptop with a long press of the power button until everything shuts off. Leave the laptop off for 30 mins to a few hours, then try starting again.
Wrong Display Mode ¶
You may have accidentally pressed something or changed a setting. This can be fixed!
Hit your F11 key (display on and off) a few times to see if the screen comes back on. Or, at startup, hit F2 repeatedly to get the setup menu. If neither of these work, you will need to check your hardware.
Touch Screen Does Not Work ¶
Your screen does not respond to your touch.
Identify Touchscreen Connection Status ¶
'System updates can change driver settings to where the computer no longer recognizes the touch screen.
First check to see if the touchscreen is connected to the computer. By navigating from "Control Panel", to "All Control Panel Items", then to "System": under the Pen and Touch section, you can see if it is or is not connected.
Touchscreen Not Connected ¶
If the Touchscreen is NOT being picked up, then a System Recovery must be performed to see if it is an issue with the operating system.
Limited Touchscreen Support ¶
'Any type of impact or hardware malfunction can cause the settings to get out of whack.
If the computer has "Limited Touch Support", first try to Re-calibrate or Reset the touchscreen. Otherwise, try to reconfigure the touch screen.
Unnecessary Software Installed ¶
Multiple hardware drivers through updates can conflict the software into not working properly.
If the touchscreen still is not working up to this point, then press the windows key + R. Type devmgmt.msc then press enter. Navigate to Human Interface Devices and uninstall HID-compliant device. Then reboot and try the touch screen again.
Broken Screen ¶
If all of the above methods fail, then the screen can be replaced.
Laptop Shuts Down Unexpectedly ¶

App/Firewall is Causing the Problem ¶
There could be an application of firewall that is interfering with the internet connection. To troubleshoot this we can start the windows in safe mode.

Right-click on each / all network adapter one by one and select 'Uninstall'.
