Read the entire article, and check that your specific laptop can be repaired in the way presented. Especially check that the fishing line can be placed in a location which doesn’t get too much in the way of your normal use (heavy users of the mouse buttons or touchpad might have problems here), and that there are locations more or less in the center of the laptop where gluing the Velcro will not affect the use of the laptop screen hinges (that no access doors or ventilation holes are sealed).

Cut two strips of the fuzzy Velcro and round the corners (rounding the corners will make it less likely that the Velcro will detach after gluing).

Read the instructions for the epoxy glue; mix it and use it to glue the two strips of fuzzy Velcro, one on the back of the display, and one on the bottom of the laptop, such that the two strips are co-linear (in other words, the alignment of one strip, when extended, coincides with the alignment of the other strip). Lenovo g460 hinge Try to make the line of the two strips be as perpendicular as possible to the axis of the display hinges.

Wait for the epoxy glue to harden fully. This can take 24 hours or even more. See the instructions for the particular epoxy you have used. Don’t confuse the setting time of the epoxy (which can be as quick as 5 minutes) with the time until it reaches maximum strength.

Close the laptop display, and cut a strip of the hooked Velcro more or less to the length required when sticking it to the two glued strips in their entirety. Actually, what is more important is that the length of the hooked strip totally utilize the glued strips when the laptop display is open. Do not use the Velcro with an open display before the glue has hardened to its maximum strength.

After the glue has hardened to maximum strength, check that the Velcro can now prevent the display from falling into the closed position. Laptops with large or heavy displays may require gluing multiple strips of Velcro, or wider and/or stronger Velcro (Velcro comes in a range of sizes and bonding strengths). The laptop in the images has a 12.1″ display.

Take the fishing line, and tie it into a loop which exactly encircles the laptop when the display is open to the working position. I used an “improved blood knot” for this. Instructions can be found in various places on the Internet.

Check that the fishing line loop is strong enough to prevent the display from falling into the fully open position (fishing line comes in a variety of strengths, use a relatively strong line which will not stretch under the load).

Glue a small strip of two-sided foam tape (like used for mounting things) on the edge of the laptop where the fishing line should rest. If it is a bother, make the adhesive on the outside less sticky by touching it repeatedly.

Optionally, you can use a plastic bag closure which has been notched (see images), in order to more easily adjust the exact size of the fishing line loop (and therefore, the exact working position of the laptop display).

The U450p feels much lighter and thinner in the hand than a typical 14-inch notebook.

Lenovo generally impresses with its keyboards and touchpads and the IdeaPad U450p is no exception.

The U450p has a traditional-style keyboard, as opposed to an island or “Chiclet”-style setup. It has very good

tactile feedback and a solid feel. Under normal typing pressure there is no flex. The keys have just the right

amount of travel and are very communicative as a result; it is easy to tell when a key is fully pressed and

keystrokes are registered. The keyboard is accurate and easy to type on quickly. The keys are made of solid-

feeling plastic and give a high-quality feel.

The keyboard is quiet enough to be used in just about any environment; it actually sounds quite nice, adding

to the tactile feedback.

The keyboard has a few oddities. On the plus side I liked the arched spacebar, arrow keys and rounded key

edges; they all enhanced the typing experience. On the minus side I found the layout to be somewhat odd; the

[Fn] and [Ctrl] keys in the bottom left corner are switched, which took getting used to. This is a holdover

from Lenovo’s business-oriented ThinkPad line; anyone who’s used a ThinkPad keyboard will feel right at home.

Additionally, the Home/End/PgUp/PgDn keys on the right side of the keyboard have a non-standard arrangement

and also take getting used to.

The touchpad is rather small but works well. Its matte surface is appreciated since it is easy to track on

regardless of whether fingers are moist or dry. The touchpad buttons are quiet and have an excellent multi-

level feel.
I did not have any general tracking issues with the touchpad. It supports multi-touch features such as two-

finger scrolling and “pinching” to zoom but they work sporadically at best.
