how to install BTI Lithium Ion Notebook Battery

1. Power down your notebook completely and unplug from any power source. Remove any connected peripherals to avoid damage.

2. Place the notebook facedown on a soft, clean surface and locate the back panel or battery compartment cover. Use the appropriate screwdriver to remove the screws securing the panel, if required.

3. Gently lift the back panel to expose the existing battery. If a connector is present, carefully disconnect the battery by loosening the retaining clips or tabs that hold it in place.

4. Remove the old battery from its bay, taking care not to bend internal cables. Align the new BTI battery so that its connectors line up with the notebook’s motherboard and battery harness.

5. Secure the BTI battery in place, reattach any connectors, and reseat the back panel. Replace screws and tighten them evenly to avoid warping the cover.

6. Reconnect the notebook to power and power it on to ensure the battery is recognized by the system. Allow the battery to calibrate by charging to full once before heavy use.

Great socks but overly snug
Size: 13-15, Color: Black 5 Pairs
Socks fit great. Very comfortable. The elastic around the ankles gets tight and uncomfortable as the day goes on though. Durable after many washes and they do not shrink. Colors don’t fade. They keep the toes warm and separated, which provides some bunion pain relief.

Size 8 - 15
Size: 10-12, Color: Black 5 Pairs
These socks were so well reviewed that I didn't quite believe my boyfriend when he said they wouldn't fit his size 11 feet. So I went and tried them on my own women's size 7 feet and yeah, no. Maybe the arch & heel part could stretch to accommodate his feet (but it would be stretched quite thin) but the toe part is already very snug on my short little toes, there's absolutely no way they'd fit his gangly toes. So I looked at the package to make sure we hadn't been sent the wrong size, only to see "size 8 - 15" on the barcode. So it turns out it doesn't matter what size you pick, this is a one size fits all situation, and that size does not fit the long toes of a tall man's size 11 feet

Quality not as expected
Size: 10-12, Color: Black 5 Pairs
Upon opening the socks looked all right they fit well, but I questioned the durability. Unfortunately, within a few weeks, the stitching started to separate and now their are holes in most of the socks rendering them useless.

made well
Size: 8-10, Color: Black 4 Pairs
These socks fit really well. Comfortable and the price is a breath of fresh air with other brands of toe socks getting crazy expensive. Just went for my evening run and they felt GREAT.
