Question about Lenovo G450 (2949CGU) PC Notebook

1 Answer

My lenovo G450 laptop keeps shutting off automatically whenever I'm watching videos or playing games.

Whenever videos are playing on the laptop for over 40 minutes or a game is running, the laptop will automatically shut off with no warning. Also, if the laptop is connected to the television through an HDMI cable it'll shut off in under 20 minutes. I've attempted to clean the laptop fan and even us a cooling fan under the laptop.

SOURCE: problem with the wifi lenovo G450

Be sure your wireless switch is on. Then check your device manager. If it has yellow mark under network adapters, then you need to download driver for that. Click here to download driver. If that won't still work, try uninstalling Lenovo Readycomm from the list of your programs in Control panel. If that still doesn't work, contact your service provider to configure the wireless settings of your pc and router.

Whenever I try to play my Super Smash Bros. Melee game with 2 players (me and my dad),It always automatic turn off. I tried every combination of black and white controller,but no working. WHY IS THIS...


Power Light Shuts Off
If the power shuts off during game play (even as much as 30 minutes after the system is turned on), then turns off and won't turn back on or the fan isn't working, the system needs repair.
