![]() Especially if you can’t power your computer on or you don’t have a removable battery. These devices can only be detected when they are turned on.Ĭhecking the battery is a little more difficult than checking the charging cable. ![]() Many people use the USB to Ethernet adapter even when there is an available USB port in the laptop. This will prevent the power supply from being damaged. Do not install it on the plug that is backward. When you are installing an accessory such as a battery, make sure that you install it correctly. To reduce the use of the power, turn down the monitor brightness.ģ.The incomplete installation of the accessories In the case of the laptop, the monitor brightness makes it possible for the power to drain even faster. Many people like to use the computer in the dark because it helps them read better. If unnecessary processes are going on, then stop them immediately. You should have a device manager in your machine to see what processes are taking place on your laptop. Also, there is a difference between wear caused by cycling a cell and wear caused by keeping it forced at full charge so even if pumping amps through a battery was possible it would most certainly not be the same as leaving it plugged in 100%.Why is a laptop battery not charging when plugged in? so what you are worried about now is exactly what was happening in the past and that is indeed not good for the battery. You can however do this by constantly running the battery down 10% or so only to charge it back up asap and run it down again exactly how you computer behaved in the past. This is not really how electricity works, you cannot 'run amps' through a battery without the state of charge changing. I was worried that it was maintaining a specific charge while still drawing amps from the battery for use That would cause an incredible amount of unneeded stress on any battery and should never happen. In the past, while plugged in, I have always seen my battery percentage bounce between the two thresholds that I set. That is exactly what should happen, a battery thats not being used and isnt filled to the brim wears the least. When plugged in the laptop runs off of AC power and bypassing the battery completely If you could see it drop that fast before but now not any longer well congratulations your battery just got better. You cannot see in a day or two if this isnt working as intended unless your battery is shit to begin with. This natural discharge should go very very slow as long as the battery is in decent condition, it could easily take a week for it to go down far enough to be rounded to a whole percent. This way youll (1)prevent the battery staying at a too high a charge level (which also creates wear) and it will also (2) prevent the battery being topped off every time it naturally discharges by a fraction of a percentage (ie 79,99%) as this non stop topping off is charging and thus also creates wear. ![]() Setting your thresholds to 80 and 70 like you have would mean that the laptop will 1) never charge the battery over 80% and 2) not initiate a charge before the level goes below 70. Charging and discharging creates wear so you want to do as little of that as you possibly can, charging/discharging continuously when plugged in would be about the worst thing you could ever do to any battery when theres perfectly fine ac available. The point behind charging thresholds is to prevent wear on your battery. So if I pick 80 and 70, the computer will charge up to 80%, then let itself discharge down to 70%, and repeat as long as it's plugged in. Lenovo Photo Library (including lots of wallpapers) Mirror of Hardware Maintenance Manuals for discontinued models Lenovo Windows Digital Download Recovery Images Lenovo Parts Removal and Replacement Videos (select ThinkPad tab) Specification guides for discontinued models When reinstalling Windows, try the Lenovo disc images, as longer battery times have been reported, probably due to custom drivers. A can of compressed air may be useful too, and a bottle of isopropyl alcohol and cotton buds are good for cleaning, but not on the screen. The only tools you need for servicing a ThinkPad are a set of small screwdrivers and a nylon spudger (for taking the screen and keyboard bezels off), and possibly a pair of tweezers. Corporate bulk purchasers don't usually go for it. Not only will it have better brightness, colour, contrast and viewing angles - you will most probably more than make up the investment when selling it. When buying a new ThinkPad, consider taking the IPS screen option if possible, as it doesn't cost much. When buying a used ThinkPad, remember to check that the BIOS is not locked with a supervisor's password and that Computrace is not enabled and activated. For IBM/Lenovo ThinkPad laptop enthusiasts.
