I am new to laptop though using desktop past 15 years. I am old person. while working laptop on battery the screen is less bright and not comfortable to read. But if I switch ON the power the screen is better for me to read. can I keep on the power switch as long as I am working and when work is over switch of power and put laptop on SLEEP mode. Does keeping on power while working spoil the battery . advance thanks.
See here Adjust Screen Brightness in Windows 10
See this also to reinstate a previously useful feature Add or Remove Display brightness from Power Options in Windows
Note - If a person adjusts their display brightness, that brightness will now be remembered as their preferred brightness whether they are on battery or connected to a charger. This new behaviour results in a more consistent and battery friendly experience. This does not affect battery saver mode settings; if a person has opted into lowering the screen brightness in battery saver mode, their display will still dim when the battery is below the threshold selected.
I have a 5 year old Dell laptop. I keep the laptop plugged in when using it for long periods. There is no need to immediately disconnect on reaching 100% charge. My battery capacity is now about 80% of the new capacity.
Just in case it was not clear from the first reply, you can set the brightness to be the same on battery.
No.Does keeping on power while working spoil the battery
Some computer makers include a utility that limits battery charging to very slightly below full charge [e.g. 95%]. This is said to prolong battery life i.e. the length of time before the battery gets worn out.
- This means it would last slightly less time if you needed to use it on battery alone [e.g. 5% less].
- If you find that you have such a utility then this is the point of it. You can use it or ignore it.
- I have such a utility. I ignore it.
- johnpd's post, below, is an example of the use of such a facility.

There have been issues with batteries on some Dell systems (especially the XPS models) where the battery begins to swell shortly after one year (in other words after the normal warranty is up). If you are switching between using the AC adapter and battery power, it could cause the battery to go through their normal charge cycle time faster. When at home I almost always had it connected to the AC power. When away from home I would normally use battery power. When I got back home I would plug it in again and it would top off the battery charge. Shortly after a year, my battery started to swell. Fortunately I was able to get a replacement as I had an extended warranty. A few months later Dell put out a recall notice for the battery. What I did after that was to change how the battery charges. I modified the start charge and stop charge numbers, start when the battery charge has dropped to 50% and stop when it hits 85%. If I know I will run into a situation where I will need more charge in the battery. I charge it temporarily to 100%. So you might want to consider this to prolong the life of your battery.

The quick answer is that you may have a limited amount of battery life (Up to 1.5 to 2 hours) depending on what you are doing. Lower brightness helps conserve battery life and can be adjusted. The battery for modern day devices uses better monitoring technology and it actually is used as a UPS when plugged in, so that any power flucuations are smoothed out.
If you are going to be in one spot all of the time (i.e. couch), you can stay plugged in. If needing to work on the go or say at the kitchen table, keep the power adapter handy for when you see the device dropping below 70 to 8-%. There is still a huge fallacy on batteries in devices. Go by manufacturer recommendations.
If I grab say my iPad or Macbook Air to work on when I do not want to be at the desktop, the only time I plug them in is when the battery gets down below 75%. Otherwise I work with it on the battery. "Beige Box" laptops and tablets tend to only last about an hour and a half with normal use. Those that state that they can last up to six hours, is with intermittent use or using for lightweight stuff like doing emails. Even the Apple products do not last past say 3 to 4 hours between charges.

thanks for all who replied. One more information (information sake) I am 93 years. brightness is set maximum 175% (Dell inspiron laptop). but with power switched on brightness is better for old man like me. anyhow thanks for all
