Hi, I am planning to buy a compaq presario v3133au laptop. For some reason, the specification of this model is not listed in the compaq website . The specification as provided by my dealer is: AMD Turion X2 TL-52 processor with 1.6 GHz. 1X512 MB DDR2 RAM at 667 MHz. NVidia GeForce Go 6150 GPU with upto 128 MB shared memory. 80 GB SATA HDD at 5400 rpm. 14.1 inch Display. 1 ExpressCard Slot. 5 in 1 media card reader. Integrated bluetooh. 802.11 a/b/g wireless LAN Pre-loaded with FreeDOS OS. The nett. price inclusive of VAT is 44,790/- Can you please tell me about any other laptops which have a similar specification with a price range of 45000? Is this configuration vista premium capable? Usually laptops which are vista capable come with a sticker that says so right? I checked the model at the dealer and it didnt have this sticker. My friends tell me that AMD laptops heat up too much. Is it so? Also, the notebook features an expresscard slot. Will i be able to upgrade the graphics capablities in future using the expresscard slot? How much does RAM upgradation cost? I intend to upgrade to 2 GB RAM. Can anyone please tell me about of the expected power backup of this laptop? The dealer says that this model will give me 3 hours of backup for a full recharge. Is this reasonable enough?
