Twisting the screen does not produce any ripples and neither does putting pressure on the back side of the panel (however, with a reasonable amount of force, you can make it happen, but nothing like some HPs and Dells I've seen, where you can make the entire screen ripple).

However, one thing that doesn't seem too well designed is the back side of the LCD panel. Although it's difficult to get ripples to show, due to its slight convex shape, you can flex down the outer plastic. I've purposely sat on the laptop closed, and nothing broke, so you shouldn't be too worried. Toshiba Satellite M645-S4055 Battery

Holding the laptop by one of the corners produces no creaks or flex, but you can really tell the laptop is under a lot of tension in this position.

The touchpad and respective buttons are all fine.

Keyboard and Touchpad

As mentioned above, the keyboard has the 5 degree tilt to it that many other Acer notebooks have. Overall, this doesn't make any difference in my typing than a conventional laptop keyboard. The rest of it is basically standard, with the exception of the Euro and Dollar symbol to the left and right of the up arrow key, respectively. Toshiba Satellite T115-S1105 Battery

The touch pad feel quite nice: smooth enough to flow easily, but it has enough friction for precise control. The left and right mouse buttons are pretty standard as well, and they produce a noticeable click when pressed. The four way scroll button works as expected as well, also producing a noticeable click sound when pressed (and thus causes annoyances in class- but don't get me wrong, it's not that loud; it's about the same as a normal mouse click sound). The touchpad is built by Synaptics, and through the drivers, you can configure many settings, including a virtual side and virtual scroll area. Toshiba Satellite T115-S1108 Battery

Screen and Speakers

The screen is a 15.4" Widescreen WXGA+ LCD at resolution of 1280 x 800. Although I could not find the exact specs for this LCD panel, I can tell you that the response time isn't bad, as "ghosting" is on par with my 16ms Acer LCD. Contrast and brightness are all acceptable by today's standards, and it is even through out, with no apparent "bleeding" on the edges. However, the viewing angle isn't that great, but on par with most other current (non "bright view") laptops. My laptop came with no dead pixels. Toshiba Satellite T115-S1100 Battery

Audio is powered by the popular Conexant AMC chipset, which serves its purpose. The over all quality is once again on par with most other laptop speakers, and it can get loud enough to fill a small room. Overall, they're not bad. Sound from the headphone jack is about the same as from the headphone jack on my external USB SoundBlaster Live and rotating the plug around does not produce any static.

Performance

The laptop is Centrino certified, meaning it includes the Intel i855 (GM/GME) chipset, along with the Intel Pentium M 725 1.60GHz 400MHz FSB 2MB Cache Dothan core processor. The hard drive is only 4200RPM with 2MB cache, and it really degrades the overall system performance, and it is quite clear from my tests that it is the limiting factor in boot and application load times. 512MB of RAM comes equipped at the timings of CAS 2.5 -- 3 -- 3 -- 7. It also comes with Mobile Intel Extreme 2 Graphics, which dynamically shares 64MB of memory. Toshiba Satellite T115D-S1125 Battery

The overall video performance is what you'd expect from an Intel Extreme graphics chipsets. It's fine for everyday work and photo editing, but don't expect to play anything more demanding than the Quake III Arena engine. This laptop can play Quake III Arena at all the lowest quality settings, but at its native resolution of WXGA+ at around an average of 100FPS. At XGA resolutions, a constant 125FPS can be achieved, even at medium quality settings. Toshiba Satellite T115D-S1120 Battery

System boot time will vary from system from system, but from power on to getting to Google takes my system 33 seconds. The ACER POST takes about 2 seconds, which is followed by the Windows XP boot process. Toshiba Satellite pro T130-11H Battery

CPU performance is excellent, as are all Dothan based Pentium M's. Best way to describe it is by giving you the numbers. On battery power, you can configure it to run at 600MHz or 1600MHz.
Although laptop overclocking isn't very popular, this TravelMate can overclock quite nicely. Laptop overclocking is just like desktop overclocking, except we are much more limited in the variables we can change. On most Centrino laptops, you only have access to adjust the FSB, multiplier (lower only), and occasionally, the RAM Timings. You have no control over the CPU VCore or VDimm. Toshiba Satellite pro T130-170 Battery

The RAM:FSB ratio is locked at 5:3, and the AGP/PCI clock can not be locked at 66/33MHz. Therefore, increasing the FSB will overclock both the RAM and the AGP/PCI clock. Toshiba Satellite pro T130-12Z Battery

My RAM won't go any lower than 2.5-3-3-7 at the stock 166MHz (DDR333) speed, so I left it as that. We can only lower the multiplier, so initially I left it at the stock 16x.

So that leaves us with traditional FSB overclocking. The stock FSB on this Centrino laptop is 100MHz. First I had to find out what clock generator I had so I could download the right Clockgen (which I did by trial and error, and whichever gave me the correct initial readings). I have the CG-CY28346 clock generator, and I used SetFSB (ClockGen would always cause BSODs at higher FSBs for some strange reason), the ThinkPad X31 version. Toshiba Satellite pro T130-130 Battery
