Why google chrome wont run properly if you have a wrong date and hour at pc, if it can guess you have the wrong date and hour?
Why google chrome wont run properly if you have a wrong date and hour at pc, if it can guess you have the wrong date and hour?

If you have the wrong date/hour google chrome will say you have wrong date and say it wont work and ask you to change your date/hour.

The question is, if google chrome knows your date/hour is wrong this means he knows what date/hour is the right one and if he needs the right date/hour to properly wouldnt this information be an information he already has and so not an information he need your help to get? 201.78.162.247 (talk) 00:40, 9 April 2020 (UTC)
 * You need to change it yourself. Date and Time wrong will mess it up because the internet server time is different. If you computer cannot keep time and date and you always need to change it, then you need a new CMOS battery. -- Thegooduser  Life Begins With a Smile :)  🍁 01:34, 9 April 2020 (UTC)
 * It seems the correct time is needed to validate the certificates the browser uses for security. I would provide a link, but the page I found for this is apparently on the blacklist. If you can't find it with Google, try Bing.   RudolfRed (talk) 01:36, 9 April 2020 (UTC)
 * Correct, TLS/SSL certificates expire. --47.146.63.87 (talk) 03:02, 9 April 2020 (UTC)


 * My reading of the question is not why the browser needs the correct time, but why it cannot take upon itself to change the local time setting. I guess that is because changing the system time requires permission that standard software does not have (precisely to avoid hairy things like a website reconfiguring your clock to pass checks on expired certificates etc.), but I could not prove or disprove that guess by basic searching.

 * My question is not why It can't change my pc date/time. The question is, if it needed the correct date time for something, why not use the correct date time it already has?177.177.210.169 (talk) 13:35, 9 April 2020 (UTC)

Sleep Mode
Hi. Just wanting to make sure that Leaving a Dell Insprion on sleep mode overnight won't damage it. It is running Ubuntu 18.04.4 LTS -- Thegooduser  Life Begins With a Smile :)  🍁 01:33, 9 April 2020 (UTC)
 * I can envision no case in which leaving a PC asleep could damage it, as suspend mode is being used as designed. Elizium23 (talk) 01:42, 9 April 2020 (UTC)
 * Elizium23 How much battery power would it drain? -- Thegooduser  Life Begins With a Smile :)  🍁 01:58, 9 April 2020 (UTC)
 * It drains as little as possible. The answer will vary based on your specific hardware configuration and battery profile. You can try it out. My ThinkPad T580 can run for 1-2 weeks in sleep mode, without being plugged in. Elizium23 (talk) 03:18, 9 April 2020 (UTC)
 * Modern computers use very little power in sleep mode. They use even less in hibernation. Do a Web search for a general idea of how much; your manual may have specific values. --47.146.63.87 (talk) 03:42, 9 April 2020 (UTC)
 * I'll say they use less. They use zero power in hibernation because it's the same thing as turning the computer off. Elizium23 (talk) 03:44, 9 April 2020 (UTC)
 * Some platforms use a "hybrid mode" for hibernation, so I was being generic. --47.146.63.87 (talk) 01:34, 11 April 2020 (UTC)
 * Why do you feel it would get wrecked? That is a pretty typical thing to do. The only thing to keep in mind is the standard advice for prolonging lithium-ion battery life, which applies regardless: don't let it get too low on charge. Do a Web search for more-detailed advice. --47.146.63.87 (talk) 03:42, 9 April 2020 (UTC)

Elizium23 Went from full to 87% overnight. -- Thegooduser  Life Begins With a Smile :)  🍁 15:20, 9 April 2020 (UTC)
 * Sounds typical. Charging to 100% actually puts stress on lithium-ion batteries. My Huawei Matebook X has a nice feature that lets you set lower maximum charge levels for this reason (i.e., charge only to 70%/80%/90%). --47.146.63.87 (talk) 01:34, 11 April 2020 (UTC)

Testing Speakers
I have bought speakers for my Dell Inspiron 3688 computer running Windows 10. I tried to use them for a live meeting with Zoom, but was unable to get sound to come through them, so I was evidently doing something wrong. I would like to use the speakers tomorrow for a live-streamed event, but would like to test them out first and be sure that I have them connected and set up properly (as they evidently were not during the Zoom meeting). Is there a web site or test file that I can use to test speakers? Is there some other way to test speakers? Robert McClenon (talk) 05:31, 9 April 2020 (UTC)
 * While I am not familiar with Zoom, the web-meeting audio troubles are fairly common and usually similar:
 * * In the lower right corner of your windows are your audio options. Is this set to the correct output (set to speakers)
 * * In Teams and Skype there is an additional option to select sound output. This should be the speakers as well. I expect Zoom to be similar.
 * * I found the following page which gives the steps for testing Zoom: https://support.zoom.us/hc/en-us/articles/115002262083

Click "play": If there's no sound, check that the system-wide volume is not muted. Check the speakers are plugged into the correct port; look at your computer's manual if necessary. --47.146.63.87 (talk) 08:14, 9 April 2020 (UTC)
 * You should also verify that the browser tab is not muted. Elizium23 (talk) 08:31, 9 April 2020 (UTC)


 * With Zoom the simplest setting for audio is to use the system default. If you can play the sample sound, then you should be able to make the conference audio come out the same place. Graeme Bartlett (talk) 12:16, 9 April 2020 (UTC)
 * You should also click "Call with device audio" on zoom to get sound. Thegooduser   Life Begins With a Smile :)  🍁 18:55, 9 April 2020 (UTC)
