Laptop display not working? 3 possible solutions to do yourself

www.exforexbroker.com In this video i explain three possible solutions to a blank, black, not working laptop display which you can do yourself before bringing it to a professional. 1) Drain “ALL” excess charge from the laptop (you would be surprised how many laptops display will fire up from this simple step). Then fire the laptop back up. 2) you may have a corrupted RAM chip (or your RAM/memory slot could be dirty or corrupted) Change the RAM and/or change RAM slots. I even solved display issues on a PC with this step. If you don’t have a spare RAM chip, order one, its cheap now days. Just make sure you buy the correct one. Below are common RAM chips for cheap. 4GB– www.amazon.com 2GB– www.amazon.com 1GB– www.amazon.com 3) Sync an external monitor to replace the display from the laptop. Hook up the laptop to an external monitor then press a toggle key (ex. FN+F5, or F4, or F10 depending on your laptop. You can do this with a blank laptop display. If these steps dont resolve your issue then it could be the back light display, video card, mother board, loose connections or many other possible causes. Post a comment if you need help or which one of the 3 steps resolved your issue. PS. if your PCs display does not come on, try to reset the cmos/bios. I just assisted a youtuber with his issue and he simply reset the jumpers on his PC and everything is back up and running now. And please SUBSCRIBE: www.youtube.com

Laptop Battery Over-charging, Solutions to Overcharge Your Laptop Battery

How to overcharge laptop battery; solve laptop batteries over-charging problem and make laptop battery not overcharged.

Some Laptop users might meet this case that the batteries have been charged because you carelessly forget to pull them out. The over-charging occurs to your laptop battery. Laptop battery overcharged means that your battery compartment with your hand is warm or hot to the touch. In other word, the charger keeps the battery at a temperature that is warm to touch (body temperature) while in ready condition. The forcing of current through a cell after all the active material has been converted to the charged state and continued charging after reaching 100 percent state-of-charge. Meanwhile, fully charged battery is stored for identification of the performance, after 12 months in storage, after fully charged, the 0.2C discharge, time should not be less than 4h.

 

When you find your laptop battery overcharged, please unplug the power source immediately. Most modern laptops, cell phones and most electric vehicles use Lithium-ion batteries (sometimes Li-ion battery or LIB). Lithium-ion batteries can rupture, ignite, or explode when exposed to high temperature. The charge time is about three to five hours, depending on the charger used. Generally, laptop-types’ batteries can be charged at 0.8C, where C is the current that would discharge the battery in one hour. Charging is usually stopped when the current goes below 0.03C but it can be left indefinitely depending on desired charging time.

Contrary some suggestions, these batteries actually last longest if the battery is frequently charged; fully discharging them will degrade their capacity relatively quickly.

When storing however, lithium batteries degrade more while fully charged than if they are only 40% charged. Degradation also occurs faster at higher temperatures. Degradation in lithium-ion batteries is caused by an increased internal battery resistance due to cell oxidation. This decreases the efficiency of the battery, resulting in less net current available to be drawn from the battery.

Tips to Prolong Li-ion Batteries Pack Life
Keep Lithium-ion batteries cool and they may be stored in a refrigerator. The rate of degradation of Lithium-ion batteries is strongly temperature-dependent and they degrade much faster if stored or used at higher temperatures. Li-Ion batteries require a Battery Management System to prevent operation outside each cell’s Safe Operating Area (over-charge, under-charge, safe temperature range) and to balance cells to eliminate SOC mismatches, significantly improving battery efficiency and increasing overall capacity.
