Replacement Battery

The following are some sony laptop battery tips:

1. Activate the new battery

manufacturers common practice is a new sony vgp-bps21 battery at the first boot with 3% of electricity should be at this time, you should not use an external power supply, but the battery in the power exhausted, until the shutdown, and then use an external power supply charge. And then also after the exhaustion of the battery charge, charging time must be more than 12 hours, repeated three times, in order to activate the vgp-bps21 battery.

2. To minimize the number of battery charge and discharge

the battery life is directly related to each charge, the battery a step forward to retirement. Beijing tips Sony laptop battery, Sony laptop repair center at: www.cheapbatteryshop.co.uk suggest that you use an external power supply, use an external power supply when the battery removed. Often several times a day if the power plug, and the laptop is equipped with laptop batteries, greater damage to the battery. Because each access to the equivalent of an external power supply to charge the battery once the battery life shortened by a natural.

3. Electricity charge and avoid exhaustion after the long charging time

regardless of laptop use nickel-metal hydride or lithium electricity, to power after the exhaustion of a certain charge (charge less than 1%), which is the best way to avoid the memory effect. Lithium also have memory effect, but its memory effect smaller than nickel-metal hydride fills completely only to use the battery to charge it after completion. Part of the charge and discharge the sony vgp-bpl21 battery which could lead to the chemical properties of the batteries are inconsistent, so the battery performance will back down. Recommended every few months to conduct a deep discharge battery to optimize sony vgp-bps14 battery performance. Specific approach is to use battery-powered, has been using the battery capacity is 0% (when the system will automatically enter hibernation or standby, according to the different BIOS setting.) Then connect the AC charger has been full to 100%. After a long period of storage batteries, and battery has a natural discharge process, has the natural discharge is over, this does not affect VGP-BPS21/S battery capacity. The first charge, you should continuously charge the battery to 12 hours, and cycle to fully charge and discharge times (see the battery maintenance section) in order to wake up completely new battery, if this is not the battery is stored for a few months use, it is also recommended for three complete charge and discharge. If a battery by 12 consecutive hours after charge and discharge cycles, or three times still can not charge this battery can not be used needs to be replaced

Works great on my Dell E6500, get about 4.5 hours in powersave mode. Computer treats it just like the original.
To get maximum use out of your laptop battery there are a few things to keep in mind:

1) Avoid frequent full discharges because this puts additional strain on the Dell Latitude E6400 battery. Several partial discharges with frequent recharges are better for lithium-ion than one deep one. Recharging a partially charged lithium-ion does not cause harm because there is no memory. (In this respect, lithium-ion differs from nickel-based batteries.) Short battery life in a laptop is mainly cause by heat rather than charge / discharge patterns.

2) The Dell Latitude E6400 Batteries with fuel gauge should be calibrated by applying a deliberate full discharge once every 30 charges. Running the pack down in the equipment does this. If ignored, the fuel gauge will become increasingly less accurate and in some cases cut off the device prematurely.

3) Keep the lithium-ion battery cool. Avoid a hot car. For prolonged storage, keep the Dell Latitude E6400 battery at a 40% charge level.

4) Consider removing the Latitude E6400 battery from a laptop when running on fixed power. (Some laptop manufacturers are concerned about dust and moisture accumulating inside the battery casing.)

5) If you have a spare lithium-ion battery, use one to the fullest and keep the other cool by placing it in the refrigerator. Do not freeze the battery. For best results, store the brand new Dell Latitude E6500 battery at 40% state-of-charge.

How to calibrate laptop battery

For, what use to be said by how much recharge is not too much stress, because if the user will become very passive, the actual battery is not so precious.

The use of AC adapter when the laptop battery is on the machine or to have also won as you have the. Circuit control the laptop is much better than a cell phone, fully charged, it will automatically cut off the charging circuit and the small current loop in order to maintain the battery charge state, the control circuit designed machines are less than 95% in the electricity began to charge, So you need not worry as the battery charging plug to the ghost will say indefinitely; If you win to save it, suggest that you put in the batteries out of a layer of plastic wrap, so the dust can be isolated and placed in a cool place, and then take a regular basis out with a look, enrich my knowledge in order to avoid the loss of activity of the battery

There is also a question we ask will be more, that is, whether there is a need to calibrate the battery, how to calibrate the battery? The answer is necessary, because the dell studio 14 battery charging in the use and unstable factors in the capacity of the laptop battery down, but the decline was not caused due to aging, so the calibration is appropriate to make this part of the recovery of lost capacity . Therefore, regular battery calibration is very necessary thing, such as the January-February time.

Such as Compaq and IBM laptops or their own power management in BIOS program provides a dell xps m2010 battery calibration feature, so the use of these two brands of friends can according to the prompts. For those who do not provide this feature the brand’s users can follow the steps below me.

1. The screen saver set to “None”

2. In the Windows Power Management power scheme will be set to “always open” and shut down equipment related to the following menu all set to “never”

3. In the Alarms tab will be “low dell latitude e5400 battery alarm” is set to 10%, the operation is set to “do nothing”; will be “a serious power shortage alert,” set to 3%, operating as a “standby”

4. The screen brightness to the highest

5. Sure all windows closed, and save the data of all previous work

6. Check that the laptop battery charge after more than 80%, unplug the power and all external devices, then if the screen automatically reduces brightness, then leave it to hit the brightest

OK, you can go to sleep, the discharge end laptop will shut off the power plug for laptop charging, so attention must be completely filled before turning, then plug the power back to the program prior to calibration settings.

The aim is to continuous low current discharge laptop batteries, which discharge state in our daily use is impossible to achieve, because the normal state we all will inevitably be changes in current operations up and down. IBM, SONY such a machine can detect the hp pavilion dv4 battery capacity before and after the change, other machines can download a program called batterymon to see, you will find, little by little restored capacity, but here to remind that, because if your battery has been excessive use and aging, and that this temporary solution is that the methods used were not there.

This method is also recommended that a new machine just friends use the hand, usually lithium batteries before use in accordance with this method is best for 2-3 times, so as to make the maximum possible to the optimal performance of the dell latitude e4300 battery into position.

1. ASUS Notebook service — no power

Laptop power supply circuit for the general, we will measure: DVMAIN, H8-VDD5, 5VAS, 5V, 5VS, VCCA, VCCP, 3V_ICH, 1.8V_ICH 12V, DDR2.5V, 3V_LAN, 3VCLK66, 3VCLKCPU, 3VCLKPCI, 3V_USB. Only with these voltage, it can constitute a power circuit, but also some of the necessary laptop repair power circuit signal: PCIRST, PWRSW, H8-RESET, IDEREST, VCC5M_ON_PMH4, THERMDA, H8_SDA1, and so on. Laptop motherboard architecture according to the principle, basically all the board must follow the principle.

2, ASUS laptop repair — but no display power

Many possibilities for this situation, we are trying to exclude, first of all it also depends on power voltage is not normal, if normal, consider a signal problem. At this time signal to be measured more: SMB_CLK, CPU_STP, PCI_STP, CLK_ENABLE, USBCLK_48M, LPCCLK_H8, and we shall be judged according to the signal flow of a specific part of the problem.

1. Do not keep a good memory or internal damage.

2. Video card problem.

3.LCD screen output problem.

4. Asus Power supply caused by CPU or motherboard and power supply voltage is not normal, power output is not normal.

3, ASUS laptop repair — boot sometimes obvious, sometimes not significant, or Huaping

For the laptop VGA for this failure occurs the situation a little more, mainly because there are VGA notebook heat, especially the VGA, it’s operating temperature is even higher than the CPU has been working at high temperatures, it will VGA or burned to the possibility of cold solder joint on the big.

1. Motherboard north bridge, video card problem.

2. Screen line problem.

3.LCD problem

4, ASUS laptop repair — boot, but the LCD screen dark

Laptop repairs in this situation in the main are:

1 LCD itself is bad

2, ignition coil

3 lamp

4, motherboard

(A) causes damage to the battery

Notebook computer battery a long time, often charge less for electricity, and even shows the laptop battery is damaged, the specific performance of a larger resistance, the voltage across the charging up faster. So easy to charge control circuit is determined to have been filled, the capacity will naturally decline. Since the battery internal resistance is relatively large, the discharge voltage drop when a large, fast, so the system is easy to mistakenly believe that the voltage is not enough, lack of electricity. Comparison of the discovery of short dell inspiron 1320 battery life, should take appropriate measures.

(B) of the battery refresh program restore the battery discharge time

Great brands have a laptop battery refresh program, we can use it to repair the battery. Example: notebook computers, which is equipped with nickel metal hydride battery (Ni-Mh) battery, the usual charge and discharge properly, causing the battery to discharge more and more time is short, less than 5 minutes left, if carrying a laptop to go to work, then it is very inconvenient, what can restore the battery discharge time?

For the above, we can use the dell studio xps 13 battery has launched the official website of the battery refresh refresh program, rehabilitation discharge time, the specific method is as follows.

(1) the use of AC power to the notebook computer, the first official website to download to a laptop refresh program.

(2) Restart computer, press F8 key to enter boot menu and select Safe Mode DOS.

(3) into the directory where the file you just downloaded, perform a dell latitude e4300 battery refresh program, reading the warning message, as required to insert the floppy disk, and then press the Enter key to execute the self-extracting operation.

(4) Boot the computer with this floppy disk, the screen prompted.

(5) follow the prompts to unplug the AC power adapter, the program will automatically Ni-Mh battery discharge, the discharge is completed, the system will automatically shut down.

(6) The battery temperature is high at this time should not start right away, let the battery cool for a while, plug the AC power.

(7) Boot the computer with a floppy disk, the file will automatically run the flash program, and asks the user whether to proceed.

(8) At this point, flash program to start to refresh the battery, the process soon, when the return to DOS prompt A:> when that refresh is complete.

(9) Turn off the computer, and recharge the dell inspiron 1545 battery until the light turns green so far.

(10) The above process is repeated three times to get the best results.

In addition, many lithium battery pack failure is the result of a failure of energy-saving core, this phenomenon can not be avoided. Because each cell batteries can not be exactly the same nature, with some slightly lower quality long after the beginning of aging, and damaged the whole (series after) the discharge curve. Interest and ability of readers to try to open the dell mini 10 battery pack, with the help of the multimeter, you can quickly find the damage to the batteries (voltage error). If conditions allow, according to the corresponding parameters of batteries can replace the qualified product.

HP’s Envy laptops are objects of great beauty, but at more than £1,000 apiece they’re out of reach for most people. If you’re feeling a bit short, though, there’s no need to settle for an ugly duckling. HP Pavilion dm3 pulls of the same trick, but for much less cash.

The aluminium lid immediately draws attention to itself, and tilting it back sees the swish, metallic theme continue inside, with the brushed finish pooling around the square keys of a Scrabble-tile keyboard. It looks simply gorgeous and the amazing thing is that at a price of £451 exc VAT, you could buy three of HP’s Pavilion dm3s(pavilion dm3 battery) for the price of just one Envy 13.

The good points don’t stop at its striking looks or surprising affordability. The keyboard, for one, is excellent. Each key has a positive action at the end of each stroke and the wide channels between each key keep typos to a minimum. Even the trackpad is free from issues, the dainty button at its top edge allowing you to disable it for longer stretches of typing.

The price you pay for such a pretty face and competent ergonomics is a slightly cut down core specification. Instead of an Intel processor, HP has chosen AMD.

HP took a minimalist approach to the rest of the design, and it mostly pays off. Like the Inspiron 14z, we like that dm3t skips dedicated multimedia keys and instead uses the top row on the keyboard for controlling playback and quickly adjusting things like brightness and volume—no function commands required. Other welcome touches include a red LED above the mute button (to let you know when it’s activated) and a touchpad lock button that changes from white to red when engaged. We just wish that the power button was up top for easy access; instead, it’s a switch on the right side.

As cool as the hp pavilion dm3 looks, the competition is heating up in this category—fast. Our most recent surprise was the Asus UL80Vt, which costs $10 less than the dm3 and performs considerably better. Its design is less eye-catching, but it gives the dm3 a run for its money. On our PCMark Vantage test, which measures overall system performance, it delivered a score of 2,829, which is below the 3,039 average for this class of laptop and worse than less-expensive competitors like the $799 Asus K40IN (3,317) and the HP ProBook 4310s (3,315). The UL80Vt managed 3,464 on this test. It encoded our 11 iTunes tracks in 6 minutes and 49 seconds (the UL80Vt finished 30 seconds faster, and the Toshiba Satellite U505-S2930 did the same test 2 minutes faster), and it converted our video in Windows Media Encoder in 10 minutes and 23 seconds (both the Asus K40IN and Asus UL80Vt completed the conversion about 3 minutes faster). When we ran that same test with a virus scan running in the background, it required less than an extra minute, which is good. Removing the antivirus software gave a Windows Media Encoder time of 10 minutes and 17 seconds, so at least that constantly-running software doesn’t impact performance much.

Question:“I have a Dell Studio 1535 laptop, and when i have the battery charger plugged in, the dell studio 1535 battery icon says “0% available (plugged in, not charging)”, and if i pull out the cord, the laptop shuts down straight away. Can this be fixed, and if so, how? I bought this laptop new around 6 months ago. Anyones help would be wicked!”

“Dell may well have knowingly sent you a faulty ac adapter. This is an issue many have suffered from. My laptop has all my work and school documents. When I accidentally move the cord like you mentioned, the whole computer shuts down like crashing and I lose all of my data. Not to mention these crash shut downs will harm my 1 yr old laptop.

I haven’t found a solution to this problem yet. I’ll definitely post it if I do. At this point, in an effort to promote accountability on Dells part and consumer advocacy I’m going to every complaint and tech site I know of to warn others. Dell should have been upfront as they knew of this design flaw. ”
