![]() ![]() It wouldn’t turn back on at first, but after I removed and replaced the battery it turned on just fine. A few days ago my laptop randomly shut off while I was on it. I think most likely this is motherboard failure because you said “It even discharges when off! (Proper “off” not standby.)”Ī little over a month ago I was given a gently used Dell laptop. Otherwise, it wouldn’t fail same way with three different batteries. If it’s not the adapter, sounds like you have motherboard problem. Maybe your adapter is faulty and doesn’t provide correct voltage? Just a guess. This happens with three different batteries that I can charge up without problem in another laptop.Īnother point is that once completely discharged whilst off, I need to recharge the battery elsewhere and then replace it in the dodgy Acer whilst the mains plug is in and on or it won’t start (with or without battery in place).Īpologies for the long post but this is driving me mad! It even discharges when off! (Proper “off” not standby.) Takes about 8-10 hours to completely discharge whilst off (even when still plugged into the mains and with the “charging” light on) during which the laptop base remains warm around the battery/motherboard connection (even without AC adaptor in place). When on and plugged into the mains, it shows as charging (according to both hardware light and Vista system tray icons) but continues to discharge at an alarming rate (c.30mins). I have an Aspire 5310 which works fine in every respect except the following: the battery discharges very, very quickly. ![]() In this case the power jack has to be replaced.įirst, the website is great and extremely useful. If the AC adapter works fine, most likely this is power jack (connector where you plug power adapter) failure. After you find the right position, it charges properly.ġ. You have to wiggle the power plug in order to charge the battery. The battery charges only if the power plug positioned correctly. When you unplug the AC adapter, it take normal time to discharge until some critical point (let’s say 80%) but after that the battery discharges very quickly to 0%. The battery detected by the laptop and charges properly to 100%. The battery discharges very quickly after it reaches some critical point. The motherboard has to be replaced (or repaired on component level). If replacing the battery doesn’t help, this is motherboard related failure. You have a very good chance to fix this problem by replacing it with a new one.Ģ. If you move the cursor arrow over the battery icon, it says “no battery detected”.ġ. There is a red cross on the battery icon. ![]() In this case the whole motherboard has to be replaced (or repaired on the component level). Apparently the charging circuit on the motherboard failed. If you replaced the battery but the problem still exists, this is motherboard related failure. If reconnecting the battery doesn’t help, most likely it’s bad and has to be replaced.Ĥ. Apply some electronic contact cleaner on the contacts.ģ. ![]() The battery contacts got dirty or oxidized and it’s not making good connection with the motherboard. The power meter utility (if available) also shows that battery is connected and charging.īut… as soon as you unplug the AC adapter, the laptop shuts off completely.ġ. Remember to check out my article about how to save iPhone battery life if you’d like to avoid low power mode entirely.When you move the cursor arrow over the battery icon while the laptop is connected to AC adapter, it show the remaining charge and says “charging”. It’s easy to think that something is wrong with your iPhone when its battery turns yellow. After all, yellow means caution or warning in other areas of our lives. Tap the green plus button to the left of Low Power Mode under More Controls to add it to Control Center. If your iPhone is running iOS 11 or newer, you can add a Low Power Mode control to Control Center. Low Power Mode turns off automatically when your battery level reaches 80%. To change it back to normal, go to Settings -> Battery and tap the switch next to Low Power Mode. Your iPhone battery is yellow because Low Power Mode is turned on. Low Power Mode automatically turns off when you recharge your iPhone battery past 80%. Your iPhone battery turns yellow as soon as you tap Turn On. When your iPhone battery reaches 20%, a window appears on your iPhone to warn you that your battery level is getting low and asks if you’d like to turn on Low Power Mode. ![]()
