Latch Locks Tight? It’s impossible to see what’s going on with the connector contact inside the battery compartment once the battery is installed, so the only indicator you have to proper installation (aside from normal operation) is the condition of the latch. If the latching mechanism doesn’t show a positive close by clicking back to the relaxed position, try reinstalling the battery. Some laptops have a manual battery lock that is operating separately from the latches, and which will not lock unless the battery is installed properly. If the latches refuse to click closed on their own, remove the battery again, visually inspect for any bulging or distortions in the package, and check the connector for damage.

Life Of Acer batbl50l6 battery Too Short? This is the main problem laptop owners complain about, and often for good cause. Older laptops using Ni-Cad and early Ni-MH batteries often ran for 2.5 to 3.5 hours when brand new, but within a month or so, would barely keep the notebook powered up for an hour. Newer laptops using Ni-MH and Li-ION batteries are much better, often holding onto a three hour life through hundreds of charge and discharge cycles. The first line of defense against complaints about battery life by the manufacturers is always, “Did you charge and operate the battery according to the manual?” Unfortunately, different laptop manufacturers seem to disagree over how to best treat batteries of the same technology, and I wouldn’t be surprised if the differences extend to different models from the same manufacturer.

If the laptop’s battery life has been slowly degrading over time, it’s probably operating more or less in accordance with plan, but if you find the operating life shortened by more than 15% or 20% within the first few months, there’s probably something wrong. Batteries of all technologies can be “trained” to perform poorly through non-ideal usage patterns, but the Li-ION battery technology is pretty resistant, and as long as you run them all the way down once a month or so, you can probably prevent any serious charging memory issues.

Is Apple 15 inch macbook pro Battery New? Purchasers of brand-new laptops are often surprised to find the battery is dead, or runs down very quickly. Even if the battery was fully charged when the laptop was boxed for shipment, that box may have been sitting in a warehouse for six months or a year before you purchased it in a store, more than enough time for a notebook battery to self discharge to an appreciable degree, even if it’s not being drawn upon. If the battery isn’t new, and you just received the laptop as a hand-me-down or purchased it second hand, there’s no reason to expect that a short battery life is due to anything other than an aged battery. You can try to recondition the battery (see the laptop manufacturer website for for software that may be available), but odds are the battery simply can’t hold a charge the way it did when it was new.

Lives Longer In BIOS? – This is one of the few troubleshooting diagnostic tests you can do at home to find out if your battery life problem is due to a hardware flaw or to the way the laptop is being operated. Enter the BIOS setup immediately after turning on the notebook on with a fully charged battery, usually by hitting the DEL key, the F1 or F2 key immediately after you power on. Some laptops display a text message telling you what key you need to hit to enter the BIOS setup, on others the message is suppressed by a BIOS setting, but you can always go online and Google the right key combination if it’s not in your manual. Once you bring up any BIOS screen, measure the time it takes the laptop battery to run down. If it doesn’t outlast the battery life under regular usage by a good margin, the short battery life is probably due to a faulty battery or a hardware failure that causes the laptop to continually suck power when it shouldn’t.

AC Adapter Noisy? For starters, this is one of those problems that tends to bother more women than men, because men lose their high frequency hearing at a much earlier age than women. Apple a1185 battery chargers typically include a transformer and some power IC’s, at least a bridge rectifier. There’s a lot of potential for humming and whistling with transformers, but they can go on operating that way for years without failing. If the battery charger gets very hot, then it’s time to check the manufacturer specs for temperature and see if it needs replacement, and check the battery temperature as well. In all cases, the acoustic behavior of your AC power adapter and charger may naturally vary with the quality of the power from the utility, and the feed voltage if you are traveling. Anytime you can avoid running a computer on poorly regulated or intermittent utility power you should do so, but at least with a laptop you’re better off than with a desktop.
