General Windows Performance

Moving to our combined results, we start with general Windows power on/off times. Some of the laptops have less RAM, which can help in the hibernate/resume tests, but most of the newer models now ship with 4GB. We run each test multiple times and take the best result so as to minimize variance.

System Performance - POST

In another ironic twist, the G51J trails the UL80Vt in virtually every test. You'd think with a substantially slower CPU that the G51J would easily take the lead, but that's not the case. Boot time in particular is very slow on the G51J, but it beats out the high-end competition in most of the other results. What we'd really like is to see better POST times; why is it that the UL80Vt can POST in five seconds but the G51J requires more than twice as long? Clearly companies are spending more time optimizing boot times on netbooks and thin and light designs than on larger notebooks.

    you say you adjust the critical battery percentage to 1%. while on a battery test thats perfectly ok, i heard (tomshardware) and painfully experienced that discharging a battery to zero is very bad for the cells.

    one time vista didnt shut down in time and the battery lost about 20% of its capacity.

    however, it would be great, if you guys made a battery guide/test and scientifically research the dos and donts of batteries. these little chemical friends are the cornerstone of our digital and mobile lifestyle, it scares me, how little proven knowledge exists on this topic.

    This is AT. The first thing you should do is a clean install since your readers aren't going to keep all the OEM crapware on the machine.

    I'd also say to make sure you're using the Advanced settings in both Vista and WIndows 7, and with Windows 7 you need to disable any sleep/wake timers.

    All the OEM software (other than useful utilities) gets removed/disabled, but doing a clean install every time has its own set of pitfalls. I try to review laptops as the users will get them, and a clean install every time is a bit much. Regardless, this has happened on clean builds as well, so the bloatware you refer to may aggravate the situation somewhat but it's not the root cause.

    As for the Advanced settings, obviously I've gone in there when I discuss things such as prompt for password being reset (to "Yes"). The odd thing is that it's only a subset of settings that get reset. The min/max CPU percentages stick, WiFi power settings stick, and so do most of the settings in the "middle" of the advanced power options. It's the first few settings and the last couple that seem to revert on a regular basis. The UL80Vt for example reverts once or twice a day -- one of the worst offenders in my experience.

    I've had it happen fairly often on both Vista and 7, after perfectly clean installs, with no third-party power software. Do not require password on wake creeps back up every so often, as does do not enter sleep mode on lid close if on AC power, even though I've repeatedly disabled them both.

    The Asus G50VT-X6, the predecessor to the G51J is very sexy. Very speedy with a cheap X9100 CPU you can buy on Ebay. Put in an SSD, buy a few extra genuine 9 cell batteries on Ebay and stick them in the fridge so you'll have a good batteries for the next 7+ years and your good.

    It does run hot but that's ok. It is a part of it's personality. I am waiting until Per core x86 performance of the latest mobile chips are over twice the speed (work done) of my existing laptop. I think I'll wait until 11nm skymont.

    In regards to longevity, I've been crunching on the 9800gs video card and the CPU for years and years with Seti@Home nearly 24/7 with no failures. This thing is reliable. I have burnt out quite a few AC adapters though. DC jack is solid. Running at 85-90C on the GPU most of the time and it really doesn't care.

    I really liked this part of the article, you need more publicize this so many people who know about it are rare for people to know this, Success for you. You May Like to check <a href="https://www.epsondownload.net/epson-xp-310/"&... xp-310 software</a>
