kazivost notebookov
-klb ktory drzi display, casom je volnejsi
-baterka, zvacsa do dvoch rokov ma len zlomok kapacity, casom ziadnu, vysoka teplota ci zle chladenie (prasne prostredie, ktore casom vyradi coolery) tento proces urychluje.
-cd, dvd a ine mechaniky sa zaprasia pomenrne rychlo, podla toho co pises skor taketo poruchy hrozia
-poruchy hdd pri zlom zaobchadzani - narazy za chody, silne narazy aj za vypnuteho stavu, vysoka teplota
-je vhodne kontrolovat priebezne prehriatie notebooku, ak je dlhsie polozeny na stole, moze byt teplota zle odvadzana. treba dat pozor, aby sa na notebooku nezakryvali vetracie otvory.
-poskodenia lcd dipleja - lokalne zatazenie miesta na dispelji po dlhsiu dobu, hoci aj z vonkajsej strany mozu sposobit flaky na displeji. dalej hrozi rozbite, skrabance, etc.
-pri neistej napajacej sieti pouzivat adapter len na nabijanie baterky, nenechavat bezat notebook napajany zo siete (toto je len moj dohad, mono je to blbost)
-predpokladam, ze protredie ktore popisujes nie su ziadne klimatizovane
kancelarie, asi by bolo dobre priamo s predajcom ci vyrobcom prekonzultovat vhodnost toho ktoreho typu do danych podmienok.

cize pozor na narazy obzvlast za chodu, prach, vlhkost a vysoku teplotu.
idelne by bolo ak by cela skupina mala rovnaky typ notebooku a nejaky kurz po ktorom by vedeli opravit niektore poruchy s telefonickou asistenciou.

co sa tyka napajacej siete tak je to uplna pohoda, lebo v adapteri mas implementovanu prepetovu ochranu, vlastne vsetky mozne ochrany co sa tyka napajania. a kedze posledneho pol roka pouzivam notebook ibm t41 tak by som doporucil nieco z ich ponuky. co sa tyka ochrany dat tak mas boot password (klasika) a uz spominany password na disky. ten funguje docela dobre co som pocul, spolahlivy, tazko rozlusknutelny (aj ked vsetko sa da ked sa xce ze jo). no a este v tej novej serii su tie spominane otlacko prsto readery, aj ked asi useless v tomto pripade. vo vseobecnosti su notebooky ibm kvalitne a malo kazive, ale vsetko sa raz musi pokazit... ale maju pevnu kostru a nejake tie narazy mu nevadia. maju aj implementovanu antishock ochranu, ktora pri manevrovani s noutbukom vypina disky (alebo iba odklana hlavicky alebo neviem co, proste ochrana proti poskodeniu diskov). prosim neberte to ako reklamu ibm, proste som s tym bookom iba spokojny ;)))

ale zabudol si dopisat ze pracujes v IBM...:) hehe, ja len rypem, tiez by som bral IBM alebo Toshibu

urcite - ibm by bola aj moja volba. pistinko ale prave spominal ze maju k dispozicii notebooky hp, na tie treba dat asi trochu vacsi pozor.

jj, antishock parkuje hlavicky na parkovisko ;)
a dokonca maju aj "odkvap" pod tlacitkami klavecnice, takze kava vytecie spat do poharika, ak viete kam ho rychlo podlozit :)

ozaj a kryptovanie dat na tych zaheslovanych diskoch ste spominali? ak nie, tak je tam

myslis to tak, ze na tych IBM notebookoch je kryptovanie riesene hardwarovo = notebookom ?
alebo ?

Security
System
Security Chip on selected models
Locking device in the IBM security slot provides physical security.
The IBM Embedded Security Subsystem (TCPA compliant) provides for authentication and encryption of data communications. The integrated 802.11b wireless lets you connect to a LAN without wires or cables. To connect to the Internet, the optional IBM High Rate Wireless Access Point 500 and an Internet phone number are required.

Password
A Power-on password (POP) protects the system from unauthorized use. If a POP is set, the password prompt appears:
Each time the system is turned on
When the system is returned to normal operation from suspend mode
A Supervisor Password provides a higher level of security than the POP. The Supervisor Password protects the system functions from being used by unauthorized users,and protects the hardware configuration from unauthorized modification. The Supervisor Password prompt appears:
When the BIOS setup screen is accessed
An HDD Password (HDP) protects HDD data from unauthorized users. Once HDP is set, data on the HDD cannot be accessed without the correct HDP. Because the HDP is stored in the HDD, the data remains protected even if the HDD is removed to another system. The HDP password prompt appears:
When the BIOS setup screen is accessed

skus si to tuna okolo tohoto linku preluskat, pripadne vyguglit viacej, ale v podstate ide o to ze je tam security chip, cize vsetko sa riesi hardwarovo na tej najnizsej urovni...
