IBM laptop battery We recently purchased an Acer EMachine laptop for my son for Christmas. laptop battery We purchased the machine on Black Friday at Walmart for $199. Well Christmas came and my son opened his gift from Santa and found that the screen was cracked. The seal on the box was not opened until Christmas. He was devastated but we called Acer to see what we needed to do to get this repaired under warranty. To my surprise, Acer’s customer service informed us since it appears to be a consumer damage that it voids the warranty and if we wanted it fixed, Dell 8N544 Battery, we need to pay $199 to get it repaired. I spoke to 2 service representatives (who did not speak English that well so I am assuming it is not a US call center they are using) who stated the same response – consumer damage warranty not valid. I requested to speak to a supervisor and was given the floor supervisor. He also stated that since it was consumer damage, I would need to pay for it. I was informed by one of the customer service reps that I would need to speak to the 2nd level department regarding the repair on Monday since they were not in on the 26th. We called Monday to be told there is not a 2nd level department and again that since it was consumer damage, we would need to pay for repair. We were quite surprised to learn that this company is not consumer friendly. We did however go to Walmart to explain all this and the Walmart Supervisor worked wonders. They are returning the product to Acer to get it repaired. Walmart is paying to have it shipped back to Acer in Texas but when we had to give Acer our address, the customer service representative again had to add that it was consumer damage although the Walmart Supervisor and the Acer customer service representative already agreed that it was not in fact consumer damage. FRU 92P1141 Do not buy Acer products – They do not stand by their product nor do they do a thing to make the consumer happy. Dell Latitude D800 Battery, Dell Inspiron 8500 Battery, Dell 8N544 Battery, Dell Inspiron 8600 Battery, Dell Inspiron 6400 Battery, Dell Inspiron E1505 Battery, I will continue to inform family/friends all do not do it – You pay for what you get – Pay a low price for a laptop and look what happens – you get crappy customer service and crappy service from a company.I have an Acer Aspire 5315 that I purchased a couple of years ago at Walmart for approx $350. It is/was no big deal to make the recovery disk.
The PC recently survived having a half cup of coffee knocked onto the keyboard by my cat. (Had to clean under the keys and let the PC dry out for three days.) I was totally shocked when it turned on!
A month after the cat/coffee incident, the battery died. The only symptom was that it would not turn on. Prior to my investigating the problem (via on-line blogs) and realizing that all I need was a battery, I looked into getting another Acer. I think it is a great little sturdy machine that does not come loaded with a lot of junk software. I imagine that’s what keeps the price low – $330 – significantly lower than similar machines from competitors.
Perhaps the users that had such issues cannot handle the flexibility provided by FRU 92P1139 Acer with their laptops. My only regret was the short battery life.Dell Inspiron 6400 Battery I will be thrilled if the eight hour battery really lasts that long without adding a lot of weight to the machine and I will definitely look into an Acer for my next machineI bought an Acer from Walmart for $498 a couple of weeks ago, mainly because of the long battery life they claim. Like many other laptops it came with no rescue disk or other disk of any kind, but asked me to make my own rescue disk using 2 DVD disks. That’s as far as I got because it bombed out while trying to create the rescue disks and never finished. Imagining the jam I would be in if the PC would go belly up without any disks to reinstall the operating system with, I promptly returned it to Walmart within 2 hours after buying it. It’s a shame these companies have gotten so cheap that they do not even provide a rescue CD or install CD with their computers.I got my Acer Laptop from my Husband for Christmas. It has been a nightmare. I’m so mad because I put all my Business information on it and it went out on me. My Daughters also went out on her too. She lost all her Pictures and Music. I wish I had never even got the ACER. It has coast me nothing but Money and Problems.Q: When I lost power last weekend, my six-year-old laptop shut down abruptly, even though its battery supposedly had a full charge good for three hours. Does the battery have a problem?
A: Yes. The lithium-ion batteries in most laptops lose a little capacity after each charge/discharge cycle.
How much? Hewlett-Packard estimates that its models will drop to 80 percent of their original capacity “after 300 cycles or about one year of use.” 40Y6799 Dell advises that most people will see “noticeable” declines in battery life after 18 to 24 months.Dell Latitude D800 Battery, Dell Inspiron 8500 Battery, Dell 8N544 Battery, Dell Inspiron 8600 Battery, Dell Inspiron 6400 Battery, Dell Inspiron E1505 Battery, And Apple says its batteries will fall to 80 percent capacity after 300 cycles, while the inaccessible units in its newest laptops will take 1,000 cycles to reach that point.
I’ve seen major reductions in run time with batteries just a couple of years old. After six years?Dell Inspiron E1505 Battery Forget it — the battery’s gone. Get a new one, and consider buying from an aftermarket vendor that may charge less than the original manufacturer.
Q: The plastic case of my USB flash drive cracked. How long can I expect it to work?
A: It may function indefinitely. A few years ago, a cheaply built flash drive’s case fell apart at my desk, exposing the circuit board. The drive still lights up and works when I plug it into a computer.With its Aspire Timeline, Acer is claiming 8 hours of battery life. That’s the same time Apple claims for its MacBook Pro 17-inch laptop, a figure we recently put to the test.
Behind the Aspire’s longer life, says Acer,Dell Latitude D800 Battery, is the combination of Intel Core 2 Duo ultra-low voltage processors and Intel Display Power Savings Technology (Intel DPST), which Intel says “reduces the display backlight with minimum visual impact.”
Acer had the longest battery life in our recent netbook Ratings,40Y6797 (available to subscribers) with its 10-inch Aspire One lasting 9 hours in our tests.Dell Latitude D800 Battery, Dell Inspiron 8500 Battery, Dell 8N544 Battery, Dell Inspiron 8600 Battery, Dell Inspiron 6400 Battery, Dell Inspiron E1505 Battery, We’ll see if its new 11.6-inch Aspire One netbook, also launched this week, lives up to its predecessor’s battery life as soon as we get our hands on one.
Where there’s power, of course, there can also be heat, especially now that batteries are cramming more power into less space. The Timeline laptops will use another Intel technology to reduce heat by redirecting airflow to the bottom side of the chassis and the wrist rest areas.
While we of course can’t yet say how well that cooling technology might work, when it comes to heat, Acer laptops have run cooler than the competition in our tests in recent years. (Our laptop testing actually includes a “lap test” that measures the temperature of the bottom of the laptop after it’s been stressed; see minute 3:10 our Laptop Buying Guide video. The hottest laptops, ThinkPad T60 thermally speaking, have been models from HP and Apple.)

Since the birth of notebook computer batteries, on the day of the debate will never stop, because of using notebook computer is one of important technical indicators, and the capacity of the battery determines the notebook computer is an important index. Exactly how to use to maximise the efficacy of battery, extend battery life? Below, we will be listed for everyone to meet some people often without instructions are in error: now the most common lithium ion battery)A first used batteries, three times before, it needs recharging 12 hours?It is entirely unnecessary. For now the notebook computer has the power circuit and perfect management system, when the battery charging saturation, control circuit breaker automatically switch to the full, so long as the filling, does not mean that you can use the longer the longer.Second, in order to prevent memory effects, to finish in charge?Each time to recharge batteries before discharge is not necessary, and is harmful. Because of the depth of the battery proved: the senseless discharge will shorten the life of the battery, the battery advice when you can use 10% batteries. Of course when the battery has continued to 30% of the electricity charge, while still had better not because memory effect exists.Third, plug in the ac, the battery down to prevent repeatedly charge?My advice to you is: no! Of course, you can take the natural discharging lithium ion battery to me, said after the battery, if have natural discharge access will appear repeatedly charge power, reduce battery life. And I gave you the answer, “no”, the reason is the following:1 now the power control circuits are notebook designed the characteristic: when the battery is about 90% (such as HP’s most models) or 95, and will charge through natural discharge to the capacity of the time for 2 weeks to a month, when the battery leave unused one month to complete the capacity of the battery charge to maintain this time, you should concern is the battery should exercise body rather than the recharging after being sidelined.2 if battery “unfortunate” was recharging, damage will not cause than long battery power decline of how much bigger.3 your data than your battery and even your laptop is much more precious, suddenly loses power not only on your notebook is an irreversible damage, it is the time of data.Four, long-term storage battery requires full of electricity?See the table below the percentage was clear: the saturated state at the initial value of relative percentage),Storage battery charging 100% temperature 40%0 degrees after the year (94%) 98 (after a year),25 degrees 96% (after a year after year (80%)),40 degrees 85% (after a year after year (65%)),After 60 ° 75% (year), 60% (3 months),Obviously, if you want to put long-term preservation battery, the environment temperature drying and let the battery remaining power in around 40 per cent is most ideal. Of course, every month to take out the battery is best with a battery, which can ensure the preservation condition, good let electricity and total loss and damage to the battery.Five, when used as possible extension of the time?1 screen brightness. But large LCD power, can effectively reduce brightness prolong the using time.2 SpeedStep open PowerPlay and save the electricity, etc. Now the notebook processor and display chip are working frequency and voltage to prolong the using time of the function, open the corresponding options can extend battery time.3 the use of hard disk drives and velocity DriveSpeed NERO: if the software, PowerBooster software can reduce the disk drive, etc, also drive speed can effectively reduce the notebook.

In July, Microsoft Windows introduced a new power options, through to the CPU and other equipment to adjust to reduce energy consumption and increase battery life. But in addition to the use of notebook batteries, what exquisite?

Q: laptop battery power to run again until all charge?
A: in this era of lithium batteries, this idea is A misunderstanding. This principle applies only to the cadium battery before. For lithium batteries, use for a long time with test again no any role, even or harmful. Because the lithium battery doesn’t exist the so-called “cache effect”. Laptop battery life only commonly with artificial damage or natural life. Basically, the battery life is fixed, 3-6 times, the charge for the average person, can use 2-4 years.

Q: when the power is connected to pulling a battery?
A: many laptop users have asked this question, then the answer is no, it needs to depend on practical usage. In the dc power supply connection without pulling on batteries battery and no damage, because the battery again after full electric power will not accept any power will inject, all the power supply directly to notebook. But when laptops overheating when running at high speed, internal or remove battery, otherwise the best is harmful.

Q: so how should correctly for laptop batteries?
A: should avoid until 0%, recharging the battery run out, because this will give great pressure and battery damage. A feasible way is in the remaining 10-25% of the power is about to charge.

From the experience of using mobile phone battery, many people may feel laptop battery recharging shall also be all light. But in fact notebook of lithium battery charge “, “light/number is limited, and all the light recharging will only greatly shorten the battery life.

At the same time, the battery should be in charge of the dry places, but also pay attention to the heat problem, this is the enemy of batteries.

The notebook computer batteries is relative to the heart, and the advantage of the desktop. Most laptop batteries and now works mostly in the time between 2 ~ 4 hours, may not meet the needs of users. Thus, for those who need to move office or often ambulating, prepare a backup battery is very necessary. Moreover, notebook batteries are used in a year later, consumables its performance will be decreased obviously, plus some customers usually don’t pay attention to and maintenance of the battery, the battery performance quickly and is not a rare example of early scrapping. How to choose a cost-effective battery is keen to know many users. We will talk about the battery.
Notebook batteries and not common battery, the user must first understand oneself before the battery types. Support machine, Most laptop computers using lithium battery, which is the lithium ion battery is common. Another is the lithium battery, but only in some high-end thin laptop. Lithium battery is commonly by core group, the protection circuit and the capacity of monitoring and communication circuit, etc. From the parameters, battery capacity is one of the most concern. Currently battery capacity in 3000 commonly 4500mAh ~ between, also have the capacity of 6000mAh equipped.

The higher the theory, at the same time the configuration used is longer. The manufacturer for laptop battery has a detailed introduction, we often can see the “six core 4400mAh”, “four core values 2200mAh”, but actually nominal battery capacity 4400mAh 2200mAh or not directly determine the working time of the notebook. When we talk about the computer power consumption, total want to use power nominal, rather than simply current. In common 2200mAh, 3.6 V core, for example, some little May 4th series components, the battery voltage, capacity 2200mAh 14.4 V. While many 14 inches above the notebook, may adopt 2 and 4 series of eight core mixed mode, voltage, capacity of 14.4 V 4400mAh achieve doubled, longer time. However, also is the core 2200mAh, 3.6 V, if the 2 and 3 of the mixed mode 6 core, its battery capacity remains for 4400mAh, voltage drops to 10.8 V, if at the time of its use capacity, and eight core battery should be. If the power to calculate, eight core lithium battery, power should be 63.36 Wh, 6 core for 47.52 Wh, four core for 31.68 Wh. If this value, the core of lithium battery 8 advantage to manifest.
When the choose and buy must pay attention to the battery appearance, generally brand battery shell mould is more normative, then when the notebook computer may be difficult or loose from the loading condition; Don’t buy when the choose and buy another coarser and label handwriting clear cell. In addition, some new batteries battery as high guard and revision of the battery, the battery should also pay attention to the electrode wear generally heavier and glossiness traces are not new battery.
