| The screen shows good response rates in our tests, but may be too slow for competitive gamers. In comparison, all tested devices range from 0.1 (minimum) to 240 (maximum) ms. » 47 % of all devices are better.

Screen Flickering / PWM (Pulse-Width Modulation)
| Screen flickering / PWM detected | 800 Hz | ≤ 30 % brightness setting |  |
The display backlight flickers at 800 Hz (worst case, e.g., utilizing PWM) Flickering detected at a brightness setting of 30 % and below. There should be no flickering or PWM above this brightness setting. The frequency of 800 Hz is quite high, so most users sensitive to PWM should not notice any flickering. In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8746 (minimum: 5 - maximum: 343500) Hz was measured. | |||

A275 är verkligen ingen efterföljare till ThinkPad Edge-serien. Även om dess kvalitetsnivå till viss del påminner om den nedlagda lågskikts-serien Edge och vi var väldigt besvikna på basens brist på rigiditet så är dom andra kvaliteterna hos A275 i nivå med andra subnotebooks från mittenskiktet såsom ThinkPad 13 eller X260.
Det som imponerade på oss mest var dom högkvalitativa inmatningsenheterna som till 95% liknar dom hos ThinkPad 13 i fråga om återkoppling och upplägg. Portutbudet är också utmärkt, med Ethernet, 3st USB 3.0 Gen. 1 och DisplayPort pass-through stöd för USB Typ-C porten. Säkerhetsfunktionerna inkluderar en snabb och pålitlig fingeravtrycksläsare, en smartcard-läsare och ett TPM 2.0-chip.
Den största nackdelen var i särklass den TN-panelsbaserade HD-skärmen. Vi uppmanar kraftigt köpare att välja FHD-panelen istället – den passar ändamålet mycket bättre än HD-panelen.
Med underhållsmöjligheterna är det lite blandat. Även om det externa batteriet kan bytas under körning tack vare det primära inbyggda icke-utbytbara batteriet på 23 Wh så saknar A275 en dedikerat underhålls-lucka. Hela den övre delen av höljet behöver tas bort för att komma åt dess SSD (M.2), fläkten eller den enda RAM-platsen.
Allt övervägt så är A275 definitivt en duglig arbetshäst med onekbara kvaliteter såsom 9 timmars batteritid i vårt WiFi-test, utmärkta inmatningsenheter, dess överflöd av portar och dess säkerhetsfunktioner. Men för över 8 100 SEK ($1,000) så tycker vi den är en aning dyr med tanke på dess långsamma och vid det här laget utdaterade AMD Bristol Ridge SoC.
HP EliteBook 820 G3 utrustad med snabbare i5-6200U Skylake-processorer går redan att hitta för under 8 100 SEK ($1,000), och det gäller även ThinkPad 13 G2 utrustad med i5-7200U.
Vi har stora problem med att hitta en övertygande anledning att köpa denna specifika laptop utöver det faktum att HP:s Bristol Ridge-baserade EliteBook 725 G4 kostar ungefär lika mycket. Men vi anser att även den har ett för högt pris. Ett pris på under 8 100 SEK ($1,000) hade varit rimligare för att kompensera för den tydligt långsammare prestandan.
