Notebook sleep and dormancy have what differentiation?
Recently there are net friend ask: notebook asus a8f laptop cpu cooling fan
sleep and dormancy have what differentiation? In the beginning of my notebook menu shutdown options see in addition to shutdown and restart, cancel there are two, sleep patterns and sleep mode, the two mode have what distinction, how to use, the following edit finishing the relevant data and share next. "Sleep" is a kind of energy saving state, when you hope to work again, can make the computer quick recovery full power work (usually in a couple of seconds). Let the computer into the sleep state like suspended DVD broadcast machine: calculation opportunity immediately stop work, and continue to work well preparation. "Resting" is a mainly for the portable computer design power energy saving state. Sleep usually will work and setting up the stored in memory and a small amount of electricity consumption, and dormancy will open documents and program save to disk, then shut down the computer. In Windows using all the energy saving state, dormancy use power at least. For portable computer, if you know there will be a long time not to use it, and during that time could not give battery charging, then you should use suspend mode. "Hybrid sleep" primarily for desktop computer design. Mixed sleep is sleeping and resting combination - it will all open documents and program save to memory and disk, and then let the computer into the low energy state, so that can quickly return to work. So, in the event of power failure, Windows from the hard disk to recover your work. If opened the mixed sleep, let computers asus a8h laptop cpu cooling fan
are going to sleep at the same time, the computer automatic into the mixed sleep state. In the desktop computer, mixed sleep usually the default is open state.
Computer mainboard failure is introduced
The computer hp 530 laptop keyboard
motherboard is more complex, failure rate is higher, fault phenomenon
is relatively complicated, the distribution is more dispersed.
Introduction is as follows:
(1) various kinds of connecting wires of short circuit, open circuit fault
Various kinds of connecting wires of shouldn't pass place short circuit,
this pass place off impassability, IC chip, resistance, capacitance,
triode, inductance components pin break, short circuit, breakdown,
Attachment, pin and power supply, ground short circuit conduction;
Printing plate line break, short circuit and welding plate off, etc.
These are all common faults.
(2) the DMA controller and auxiliary circuit fault
DMA controller function is stronger, higher failure rate; Auxiliary
circuit chip and input signal circuit is also easy to produce the fault.
(3) RS - 232 serial interface controller failure
The PC hp 540 laptop keyboard
serial interface controller has an independent, also have and other
interface of together. Serial interface failure rate is higher.
(4) clock controller, bus controller failure
Clock controller, bus controller, bus driver, control command chip, all the possible failure.
(5) the memory chip RAM fault
PC machine memory chip is more, utilization rate is higher, chip itself also higher failure rate.
(6) data bus fault
Motherboard of CPU, memory and I/O devices data transfer bus, bus buffer
register/drive, etc, also have different degrees of failure.
(7) address bus fault
Performance in the motherboard CPU transfer address of the address bus, address latch and address register/place such as drive.
(8) memory control signal and address generation circuit fault
Refers to the RAS/CAS row/column address gating signal, line/column
address delay control signal and row/column address of the circuit
error.
(9) individual socket, pin loosening and poor contact fault
Refers to the hp 550 laptop keyboard chip and socket for rust, oxidation, elastic abate, pin sealing off, broken and switch bad contact and produce fault.
(10) I/O channel slot fault
Refers to the I/O channel slot of the copper sheet off, elastic abate,
broken sub, pin virtual welding, sealing off, dust too much or fall into
the foreign body and produce fault.
(11) fault caused by the special circumstances
Refers to by shock, strong earthquake, electric shock, voltage rise
suddenly, load does not match or design is not reasonable and produce
fault, as well as for installation, setting and cause by misuse man-made
fault. Timer, counter, interrupt controller, parallel interface
controller chip will also produce fault, but the general failure rate is
very low.
(12) power controller failure
General power output controller current is larger, calorific value is
large, if control chip or integrated block quality is not good or bad
heat dissipation, high failure rate. And its surrounding power filtering
capacity for long-term work in high temperature environment, also can
because electrolyte dry cause failure, thus cause power output ripple
caused by hp 6530S laptop keyboard increasing motherboard work is not stable.
The fault is not generated in a motherboards, there are 60% of fault can
lead to main board cannot start the work; 35% of the fault will make
the mainboard doesn't work properly; In addition 5% for random special
fault, for the performance of the motherboard condition is not stable.
