The ICONIA W510 or W511 have two physical processors.
Hyper-threading has been enabled to split them into two logical processors each, making a total of 4 logical CPU.
Not a good idea as far as I am concerned.
For example, batch processing a number of jpg pictures with Irfanview is very slow, using only 25% of the available CPU because it runs on a single logical processor.
I can accept that mono thread applications cannot benefit of the 2 physical CPU, but why restrict them to 1/2 CPU?
Normally, an hyper-threading enable/disable option should be available in the BIOS, but on the W510/W511, there is no decent BIOS since it has been replaced by UEFI, with a very limited of options.
Honestly, I did not aski to the ACER support, because I am very disappointed by the answers received so far, rather looking to escape the warranty than trying to help the customer.
Examples:
- "how can I boot another OS, like LINUX or DOS from a USB drive?"
=> Reply from the support: "you can't, and in case you succeed, this voids the warranty!"
- "My keyboard has lost a a key, would it be possible to procure a replacement key even "white" (unmarked)"
=> Reply from the support: "We do not have replacement keys, you should procure a full keyboard and this is not covered by the warranty."
Practically, this means procuring a 100€ keyboard/docking with batteries set to replace a 10cents plastic key.
Unbelievable!
The W511 is probably the first and last ACER device that I will ever buy, not due to the quality of the HW, but due to their disappointing support service.
