  1. If purchasing a stronger PSU (for example, replacing the 500w PSU with a 850w PSU) could I keep the wires from the 500w PSU and use them with the 850w one, or would I have to purchase new wires?

  2. Would it be possible to remove and upgrade the CPU by any chance? I know that the Omen 880 comes with and AMD processor, but I would like to upgrade it to an Intel i7 processor sometime in the near future. Thanks!

  3. Sir.. I am using HP laptop… The battery is very weak. Shutdown the laptop in few minutes… How to repair the laptop battery…. The laptop works fine with power supply charger without the battery… So how to repair the laptop battery as safely….

  4. If you wanted to replace the power supply with an 850 watt would you have to be concerned with the size of the new power supply, or is a power supply size fairly universal?

  5. What is the maximum cooling fan size you can put in this PC? There is the 120 mm cooling which is used in the upgraded models for liquid cooling the CPU. Is there any way I could make that a 240 mm fan or add another liquid cooling fan some where in the case for the GPU with out getting a drill and making my own vent? I understand the power supply would need to be upgraded as well in order to accommodate the new liquid cooling, but is it possible to take more advantage of the empty space or just increase the fan efficiency to cool the GPU? I would really appreciate any advise y'all could offer!

  9. Dont know if anyone here can help but I'm shits creek without a PC. On Tuesday after turning off my PC the night before I was unable to turn it back on. Pushing the power button did nothing. Green light is on in the back but nothing. Held it down a few, nothing. Finally after looking up on line I was able to turn it on by holding down pwr for 5 sec, unplugging, then while unplugged hold down pwr for 15 sec ,then plug in hold windows, b, and power and it turned on. But later in the day it turned off twice after instances of being away for more than half an hour which would normally bring the sleep screensaver thing up. But instead turned it off. So I did the trick and it turned on both times. Next day it was turned off again and was able to turn it on with the pwr trick np. Worked fine the whole day. At the end of the day I shut it off so it wouldn't be on all night. Went to work came home to try and look at my BiOS based off a suggestion and it wouldn't turn on for shit regardless of what I did. So I said screw it and called hp and was able to turn it on after unplugging and holding pwr for a full minute. with the computer on we updated bios in hp support assistant, restarted and shut off. But it didnt turn on. so I did the minute again and it turned on and we updated any other updates I had. Restarted and shut off. and this time it was actually to turn on without doing anything for the first time this week. Friday rolls around and It was shut off again and wouldn't turn on unless i held it unplugged for a minute. now today nothing is turning it on absolutely nothing. I have no clue wtf is wrong. It's a new PC less than a year old nothing is dusty it's never overheated and my keyboard is not set to turn it on. So its midnight and I'm frustrated. To the 2 people that are gonna see this any suggestions? And if u tell me to check bios I cant cuz that would require me to turn it on
